	528afa2c7bb14c6f82a589ae91ca7e6edc31401e	Brendan Eich — Tidy up globalShape mismatch reporting.
	02c5e041a0eff15577a22f5ae083d545a7bcbf98	Andreas Gal — Merge.
	a08ac138bc415c7b6efd26714e61176c21c2bb0b	Andreas Gal — If we expect a concrete value but see an undefined come into the trace, convert undefined to the concerete value.
	f6391f7b7fde7144dadbfcb54195380bf6ab318c	Andreas Gal — Export js_NaN.
	0a4e4719801a0a8b8dc63258fedb00f1f5b36198	Brendan Eich — Merge.
	2a47378513b5291de3afd99c1e07625baaca89ad	Brendan Eich — Use JS_FRIEND_API for new JS_ArrayToJSUint8Buffer, etc., and use it on prototypes and definitions (fixes some platform builds).

	7c2d2ad1f53160ceb5b3776b303012a89afed039	Andreas Gal — Remove bogus fadd +1 check at the end of the loop. We have long switched over to starting slots as int and hence n++ will be emitted as integer add with i2f, so checking for i2f only is sufficient.
	8631c4e861e63a7813042a4077aab7df912eeb99	Andreas Gal — Increase HOTEXIT to 1 (from 0).
	d534c69afb967cf7ff73ba6e2c8a5be0a690b289	Andreas Gal — Eliminate redundant BoxDouble(UnboxDouble) chains.
	2b03a4f6ccdba276a37508c38aadec2ae2287917	shaver — say what we're returning from from EnterFrame
	433e0fd6163171a27f80f0faa59f6cff2b06786c	Brendan Eich — Merge.
	b1e860f92cda4739dbc8d1c8170181483ccd9d79	Brendan Eich — 1. Add activeCallOrGlobalSlot, used by JSOP_NAME, JSOP_CALLNAME, etc. recorders to cope with Call objects on the scope chain, if they represent still-active frames covered by callDepth.
	3bb542e73570406978f554ae9cab714a88d40d6f	Brendan Eich — Defer eval'ed script destruction to next GC; expose js_obj_eval for tracing.
	9be727cc7214407a366cb1fe8e46b4d14ec7b479	Andreas Gal — Support multiple returns from called trees by continueing the outer tree with a new nested guard.
	a2de55ade75e7441a74334fd2d3135b309ae5586	Andreas Gal — Restore state.sp and state.rp before the nested guard exit point so we can have a sequence of them and still have rp/sp adjusted correctly.
	163eb5c5f0de59597cde084353e50e88672a322f	Andreas Gal — Push actual guard that failed in a nested call, not the expected.
	5624964c08c3e19a546bb0c2d94b7a5643e450c7	Andreas Gal — Merge.
	85af1ede7663702f72c235712c031a6d97d4085d	Andreas Gal — Don't emit a guard at the end of CALLNAME and friends since the values CALLNAME puts on the stack (callee, this) are not seen by the interpreter yet, and thus get store killed. Instead, emit the guard in CALL, at which point the values are properly stacked.
	dca5d78f252fd09aa0a04d352604494e2b69ce10	shaver — fix js_IsLoopExit to better handle for-in exits, r=mrbkap
	471789d46ccddaa7d3e82ebe1811e2bf8bb612ac	Andreas Gal — Add a switch to disable the oracle, in which case we never demote any slots.
	3a45246c0268a6637f42eabedb351b8ac213ce08	Andreas Gal — Clear the oracle on every GC.
	bf2b047ec8a59b15a3f505fcd24bfa54cfd53078	Andreas Gal — Merge.
	923cfab235b4c18ca1704f1b86a84c15f3dee019	Andreas Gal — If at loop entry we expect a double, but at the loop tail we store an int because we suck the i2f into the side exit, we have to explicitly cast back up to double using i2f otherwise we won't be able to make sense of the value when we load it at the top of the next iteration.
	086ea24c34c0e5d2eee41586117fa76205d4f738	shaver — disable vprof building so that we can build on XP
	5aeb914594ac2513768ad7cf542b35782e03d68d	Andreas Gal — Add a way to clear the oracle.
	4af1777047bad9b6922aeb32b6664d48c57af58a	Andreas Gal — Merge.
	f60ed4ad16aa5294103f47dbb14e6aeac674e882	Andreas Gal — Clear global slots and global type map when clearing the code cache.
	733c550be0fb98823ef15aa8a8175d6a74ec5af8	Andreas Gal — Backed out changeset be63a51a0a3b. Breaks tofte if run from ./time.sh.
	0530e5b075a5a20253a5f0001ccd6a1036a2b892	Vladimir Vukicevic — b=451242, use fast-paths for dense array to uint conversion in canvas
	109ca6e80874e97a4dfa4accb6a514f1956d0e14	Vladimir Vukicevic — b=451242, add fast-paths for dense array to uint/int/double buffer conversion; r=bent/mrbkap
	be63a51a0a3bb906343db5d32956bbbb13995f6d	Brendan Eich — Don't disable property caching in eval (this requires GC'ing eval scripts). Do tolerate active Call object at head of scope chain in record_JSOP_CALLNAME, and go straight to the stack slots.
	a5ecf48dd03b06dbe95868d6af8a132f745a0341	Andreas Gal — Stub the getter and setter on class prototypes and constructor (bz, r=brendan, bug 451154).
	9ce88c583712855f05cd39623356b0deceac9fb5	Andreas Gal — When adjusting integers to doubles in tree calls start with the current stack frame only.
	15633eda8a000cd31977f563717d77217bbd244e	David Anderson — Fixed some valgrind whinings (not actual bug fixes).
	5b8ea41c245cd655f811b886e0b9204ae2e96e9d	Vladimir Vukicevic — wrong condition check in nanojit with qjoin(qlo,qhi)
	ff04efe8e91d347238f31a21a2e08119d07bb39a	shaver — re-merge from mozilla-central for post-freeze backouts
	89e8d4741fa6e8fc54b636f3f7a457bad85f2b46	David Anderson — Fixed typo that broke the tree. Sorry!
	a9f2d947550b544c6c8b54b780f5ab8590af4ed9	shaver — default to non-verbose for DEBUG, set TRACEMONKEY=verbose in env to go verbose
	5e68a48895e8c3367249f3451b42ddc6005987d0	David Anderson — Another portability fix. math-spectral-norm is crashing in the test harness so keeping 64-bit JIT off (everything else works).
	4b018191e4d10cdd66cbbb58c2e3577c6c3ed699	David Anderson — Merge.
	217396e56216103584de6be414be0dc497213b92	David Anderson — Merge.
	c02916331f8b96ed51c51e732e57185ebbfb7245	David Anderson — Merge.
	6c6734d3095a64d9d78b5960891c018ca66154df	David Anderson — More AMD64 fixes (release build works now, and fixed verbosity bug).
	08e1675310a9805b30572e4377f02c9c6eb7d71a	David Anderson — AMD64 trace-tests.js passes now (hacked in LIR_qcmov opcode, corrected builtin return types).
	4b24cd03cdda3715a141e9ab1d5a72d54aa6763f	shaver — improve JIT-control pref naming, add one for chrome JIT, add defaults to all.js
	53c8273602533d6cba68bcc9de66b3f2bf36806f	shaver — merge from mozilla-central
	c8a473e77591cd71dfb8687ea32bc623189515c9	Brendan Eich — Add str + obj concatenation for 3d-raytrace.js.
	4ef12bfb79480fb4520b76d7ecb291cd291bcc1a	Andreas Gal — If the outer tree has a slot in an integer register, but the inner tree expects a double, make sure to promote the value before calling the tree, otherwise the inner tree will read the value from the stack incorrectly.
	5a34f3b19521d97a89fa6bcbe424b2b4fb7dcde9	Andreas Gal — Correctly calculate tree call stack adjustment, even if we don't have any arguments in the current frame and hand pick some cleanups from the backed-out changeset.
	45af6228d6fa990a59b3d68fdaf71280ba91ab95	Andreas Gal — Back out multi-trees. There is absolutely no way this will be debugged in time for tomorrow. Need a bit more gdb man-power.
	34b597daedf940f5252ae7df93ad1c68796e3e4a	Andreas Gal — Always blacklist the first fragment in the peer list, and blacklist if we see a loop that is not type-stable.
	9a1eb24729628bb9991e1a9fc3b463f214333f8a	Andreas Gal — Don't build trees inside tree calls if no suitable tree can be found (for now.)
	50a8c7f0e0443eb98d97359161540ad3d8ceff6c	Andreas Gal — Improved debug output.
	39e2365052c6870d6654f0b6b41ef3f02cfe40e2	Andreas Gal — Add debugging facilities for typemaps and fix sp_adj calculation for tree calls.
	3eb15b6268b6ebd18ef5308e13fe2e9ddbffd0e7	Andreas Gal — Support multiple fragments with different entry maps per PC location.
	a8f3d5e798d8509bbd97f405bf5dba356fb94096	Andreas Gal — Clear out the list of global slots when the shape changes.
	ab683b57667d8e0a280e8c7b4f009a0d9acfc0ad	Andreas Gal — Emit the tree call stack setup code before executing the inner tree, otherwise we might see stale references to instructions prior to the call that no longer guarantee certain types (since the inner tree overwrite them.)
	24b0a322e1630a92216114b9bb8cc450aecb1c2f	Andreas Gal — Merge.
	fca2a565f6c1876f937ce23671af4512366f4de9	Andreas Gal — Intern globals per-context, not per tree, which allows transitioning between trees that use globals. The type of all global slots compiled code uses is expected to remain stable, otherwise the entire code cache has to be flushed. Changes to the shape of the global object also flush the code cache. Working for trace-tests.js, but fails math-partial-sum.js
	d1323b231ea802dd5ed061d91b60a0a0059ac1b3	Andreas Gal — Add a global type map to the monitor and rename slotList to globalSlots.
	d24800fa1c622016a406a968b0783709bec24df7	David Anderson — Disabled 64-bit JIT for now, failing 3 test cases.
	fbf9008c1766ca296c069940faebf0149da9892e	David Anderson — Merge.
	f2733b1b17bfca22798467d10ddb03c9bcdd238d	David Anderson — Fixed codegen bug for amd64 64-bit binary ops.
	3869eb3935df8e17bf878630e4b62df4817f7f7a	David Anderson — Fixed AMD64 accidentally treating the shape as a 64-bit integer.
	718eba62955ec24281a96aa3d46061a1720bdd6a	David Anderson — Merge.
	a54d34ab5bf70cc6dc65e7e17ce84260a375f895	David Anderson — Fixed some bugs in the AMD64 port, still crash in 5 sunspider tests.
	8fdc2ff1bd9b153ea9414c81a955b5b6b41ddee3	David Anderson — Added AMD64 JIT building to the makefile.
	d2d90d339c5b4128371edf9e39ca760df49c3e55	David Anderson — Improved AMD64 nanojit compatibility.
	08886183ad42b3f9aafee4aafb6001d87a326a1e	David Anderson — Fixed compiling on AMD64.
	1e456b6bceae58a19b41d09532e1ba6387ba397f	Brendan Eich — Back out changeset 1d0574db8320 (for 450997), it was based on a bum steer.
	bf96539355bf5bff8e91d6ef074d7b4fd0e056a5	Brendan Eich — Add a final js_ReconstructStackDepth assert after setting fp->regs->sp in js_ExecuteTree's bail-out epilog.
	5f757786525eca4074a9e94d17a1d885e98adbb0	Brendan Eich — 1. Fix json2.js (it crashes later, another bug) to restore a non-empty stack for a call with missing args after a nested bail-out. This involves changing js_SynthesizeFrame to return the number of stack slots it reconstructed that map to native slots. It also means not counting the missing args in the spdist uint16 pushed onto the state.rp stack (this was the root of all over-counting evil, for this bug).
	ed59b903cacefe21c464f2c0a0f8d5107f300c29	Brendan Eich — Cosmetic cleanup.
	793e5bc71728a9ace15f8221b1ec628b815739b1	Andreas Gal — Add a place to store the current shape of the global object as we add slots it the global slot list.
	8c2ccabb8b622cfb65be694f79435c85add21e4a	Andreas Gal — Add a global slot list to the trace monitor.
	21f26b41d7e3e73eb75bbc366e369191c42b798c	Andreas Gal — Merge.
	1afa227e9b73020c6bf70287b6280381f90fc418	Andreas Gal — Make sure to trasm the vmprivate of dependent trees as well.
	069a7b6f1012f58808f2370cc3002e46b738a0ce	David Anderson — Updated nanojit for the AMD64 patch.
	1d0574db83207d6850eef938288142212b0aa110	Andreas Gal — Tighter fencepost in getTop, don't overshoot the stack (450997).
	98adb85d1f02abbb33bab45e45eb51ddfd28e799	Andreas Gal — Doh. Deep bailots are pretty rare and js_SynthesizeFrame already uses the fairly slow js_ReconstructStackDepth helper internally, so anotherone to avoid counting stack slots via spbase can't hurt.
	48501e6d56bcc4238beedfe0cba4df3254bec7ed	Andreas Gal — Merge.
	16ae20bd96ae0c0fe121dcd252adcdbb78398ad4	Andreas Gal — Add a method to type map that captures missing slots (which have been lazily added to the slot list since the type map was created.)
	cda21775af056796c734c545ac5668f1e9b6fd49	Brendan Eich — Fix missing paren in comment; also s/scope/frame/ in same comment.
	6c1e358ce7a913f529a9e968b2adc28c5e9cff48	Andreas Gal — Extend the globalTypeMap import(), not in the caller, since we missed extending it in case of re-reading registers after a tree call.
	629fae5234d803ffd3754abc5d38d39bcb78897f	Andreas Gal — If RecordTree is triggered, create a new peer fragment (or recycle and unused one) if we already have a tree for this location.
	c874c018538966ead950158c0b3190b7ea11de1b	Andreas Gal — Try to execute the tree first, and if that fails worry about counting and triggering compilation. This speeds up trace activiation by a tiny bit, but makes code that we can't trace a little bit slower. We use a micro optimization to bypass the call to js_ExecuteTree when its clear that it wouldn't find a tree to executed to reduce this overhead. This change is necessary for multiple trees per bytecode location.
	2ad80e2e356d27296fa7f1b99e96da182975222c	Andreas Gal — Give root fragments a treeInfo decorator only if the trace was successfully compiled. Otherwise just keep a reference in the recorder and delete it when the recorder is destroyed. Review welcome. The involved state machine is a bit complex. Added lots of asserts as safety net.
	c651b4e5c5284c0c1ab77bc8bc72165a2dea39aa	Andreas Gal — Only capture the shape of the global object in a tree once that tree tries to access a global, and only check the stored global shape in trees against the current global shape if the tree actually uses globals (which also doesn't trash trees when global variables are added if that tree doesn't actually use globals.) This is approx. a 1% win for sunspider.
	c072d3b7af1f236dd48654804dd14f0c6eb807b3	Andreas Gal — Change interface of js_ExecuteTree to indicate which of the peer fragments it really executed (since we soon will have more than one tree that could be activated for that particular bytecode location).
	a5e518ad4bad36185331e9743c3b3e74be91b0fe	Andreas Gal — Add a ->first pointer to all fragments that points to the first fragment in the peer list. This is the fragment we do JIT throttling/blacklisting on.
	98d0efcc53566f5cfc446798747f05a889d55cde	Andreas Gal — Append peer fragments at the end of the list (so f->blacklist() always counts against the same fragment).
	52e95353080a9db72d3762a7c72d818b04c3279c	*Andreas Gal — Add a simple script that calculates an aggregate score over all tests running with the jit in t/.**
	2161a2f00ce89eb8ce93281ca8a38d51f4836fa6	Andreas Gal — Merge.
	bfcedf35495326f052a253dea7e9cb35fa0d5b92	Andreas Gal — Add the concept of peer fragments to nanojit. Each loop fragment can have a number of peer fragments, which we can use to have several different specialized variants of a loop (i.e. for different types). The makefile doesn't pick up the change to Fragmento.h, so make sure you clobber by hand or you will end up wasting an hour of your life in gdb (like me.)

	735b68bb8168dfdf576c6ac1f6d67eabc4014164	Andreas Gal — Don't allow inner trees to lazily pick up any globals since we currently can't handle that. We already ensure that we don't inline trees that have globals. This patch merely makes sure they don't get some additional globals on the fly.
	6c6266b8311c947a864542560bcf5118a51b36e8	Andreas Gal — Similarly to attaching new branches to a side exit, we might end up with a partial type map when exiting from a trace during tree execution, so make sure to merge in missing types from the tree's entry map in this case as well.
	353145f415a56028175915f128c448e6ee2e0780	Andreas Gal — Add test case for type map merging (450535).
	cad6ca9a1e79467153c74a95fd660743913b7a1c	Andreas Gal — If we extend a tree along a side exit that knew about fewer global slots that we have now in the tree, merge in the types for those additional slots from the entry map (450535).
	ceab60d4090c0486b183aaefbbd7b301dccecd1a	Andreas Gal — Funnel all write-backs to the stack and the global frame through TraceRecorder::writeBack() so we can intercept and manipulate them in one central location.
	7e0cc7db204a4c650cf0893932fdef8af178f9e4	Andreas Gal — Enable nested trees by default. This is going to be exciting.
	9979c1aa2bf236914c3e449c9a2001257dc6c1b9	Andreas Gal — I honestly to god don't know why this change is necessary but with this nesting works now for SunSpider and all of my test cases. The stack layout calculation needs some reviewing, seriously.

	7c90cf9d9b0e923d059b7a87ef9b3ed5376e8b9a	Andreas Gal — Change sp_adj in guards to always reflect the current stack depth, so if we enter a trace/loop with something on the stack, sp_adj will reflect always at least that minimum amount. InterpState->sp now always runs in parallel with regs->sp of the current frame. This breaks nesting badly. I really need help with the stack layout logic.

	161cb76cb8f0e1d741ec1e0032ac46c4e7a220e6	Andreas Gal — Assert on the recording table only if we have enabled the tracer (446551).
	f80f08b0d8fca4e4fbf70f2b1ce48227b9aeafb0	Andreas Gal — Write back outer tree frames, but exclude the current frame (which the next tree will do). This still crashes the trace-tests.js test case with nesting enabled and for the life of me I can't figure out why (try with TRACEMONKEY=nesting).

Also assert in threaded interpreter BEGIN_CASE and DO_OP (from END_CASE) that we either have no recorder or are using the recordingJumpTable.
	78655198504628022c167e2ec057806a99c4e54c	Andreas Gal — FlushNativeStackFrame currently only handles the innermost nested trees writeback, so at least make it use the proper adjusted stack base for that.
	df0ca7630874415cb040fe8af267e478ab509202	Andreas Gal — Update inlineCallCount with the total call stack height, which is the sum of rp_adj and any adjustments nested trees added. Also make sure to read all stack adjustment information from the tree we exit on, not the tree we entered (might be different in case of nesting.)
	57bfefe8dfc3f66251a0b52fa9c719a8c8296cd8	Andreas Gal — Print relative stack instead of absolute stack address upon side exit (debug mode).

	7dd001982f576277d739c45206b3f84b9232c074	Andreas Gal — Don't call inner trees if they use global slots since we don't support those in inner trees yet.

	1b635268db9105907d457b5e8e57f7db363b55a3	Andreas Gal — Blacklist a trace if we hit a global shape mismatch. This makes us suck less on date-format-tofte until we find a way to fix the property cache misses.

	dd8d7205f3925052dda9157476ef3ca6ab076fe3	Andreas Gal — Don't cache loads in import into the nativeFrameTracker, since when coming back from a nested tree we re-load the frame state into registers using import() based on the called tree's state, which pushes loads into the nativeFrameTracker that are relative to the inner tree's call depth. Only cache on writes now, which should be always safe.

	966c38b7fc2a3b05315f2f427dfb89dafec5c1d9	Andreas Gal — Hands down the hardest bug I had to debug in TM so far. Make sure to read back any registers an inner tree might have changed before writing out the typemap for the nested_exit guard, otherwise we might be pointing to old stale pre-(inner-)loop state and pick an incorrect (in this case too narrow) type. fannkuch=2.8x with this.
	e36360dacbd3498d39e4f6cf9f7ad106bb7b73a9	Brendan Eich — - Add String match and three replace overloadings, and allow known native matching to continue in search of exact match (not best, and not abort on first mismatch).

	a6ec5664777b3694c079cdb52a3f04b40fdd3091	Brendan Eich — Back out extra gcflag param change (859b9a23adbf), I set bad precedent and will back out previous such shortly. Want cx->gcflags instead.
	7a9d86ec587f67e02bb2b0597b31cb9b800cd414	Brendan Eich — - Trace JSOP_NEWINIT/INITPROP/INITELEM/ENDINIT, which required extending the FastNewObject builtin to create a dense Array or a new Object (easy to discriminate on the constructor function's u.n.clasp member).

	2479e8d30a77a7fe385b80225f5fba082da8d288	Brendan Eich — Match native map guard specializations in tracer to interpreter, particularly to skip up the proto chain from a dense array in JSOP_CALLPROP (json2.js showed an abort here, pointing to the tracer/interpreter discrepancy).
	e94e5a5eb08204ca1873591722778193f196e9bf	Brendan Eich — Fix JSOP_FORLOCAL to push false when guarded conditions are false while recording (449961).
	4920eaced572295282be1484500cba0ee10a749d	Brendan Eich — - Avoid unnecessary FASTCALL builtin wrappers for existing js_* library-private or friend functions, which could be (and now are) fastcall (JS_FASTCALL). A couple of builtins avoid name collisions by using js_Fast instead of just js_ as their name prefix.
	f9e81741366991654c9c5f40467dade2343e1cf5	Brendan Eich — - Test JSVAL_BOOLEAN tag in TraceRecorder::record_JSOP_TYPEOF, assert no holes or other pseudo-booleans, to unify false/true/undefined testing.
	8dfcda7e63b34c14e05114d790409f9b5b04289e	Brendan Eich — Restore C compilation support to jscntxt.h, used by liveconnect (only one file now: jsj_JavaClass.c had no need to include jscntxt.h).
	7746c011a0a777d04df7bd53e5e785c7f40cd88e	Brendan Eich — camelCaps test names restored (NewTest => newTest, etc.).

	547989cb40718748efb78e0fce9b5df742bc3738	Andreas Gal — Support calling of nested tree from within inlined frames. When we call a tree that tree expects to be the top-level tree, which means it assumes callDepth=0. If the call of the tree is within an inlined frame, thats not true (callDepth > 0). We adjust the native stack pointer accordingly before calling the tree, and then restore the value of the stack pointer after the call. Fancy stuff.
	72600789bcb5bede25d2d6a71983d3453d60bd98	Andreas Gal — Remove ip from InterpState. Calculate the new pc after a trace side exit relative to lr->from->root->ip, which also works if we side exit on a different tree than we entered (which can happen in case of nested trees.)

	6926240f694dd0bc4736137c93b9e5493072c238	Brendan Eich — Guard against shapeless callees, with tests (more to do here, can't break the unknown callee case yet, but it should be breakable).
	ba3f7041b98eb57323a82df86a969b62c6e7cb00	Brendan Eich — Merge.
	f180eba5b24751c2ab13e42c337f950d33a3f152	Brendan Eich — Get operator new on interpreted functions working, along with JSOP_SETPROP on an unmutated object, or one of the right shape but where the setprop is adding the next property, and it's not in the object yet.
	d2282134b40679c8a4a5f1e248f4ff07afdc0f5a	Brendan Eich — Better idea for avoiding level-1 property cache collisions.

	af2af6f68095b78a2350f2af270e21f5d7f0f58e	Andreas Gal — Add very preliminary nesting for trees. This is disabled by default. To enable set TRACEMONKEY=nesting in the environment.
	6f5b4c7001c7c5d95b37c25af1caa76e39071a36	Andreas Gal — Don't activate a tree if it has globals, since we can't handle that yet.
	33e1cceddcd721421eaad6139954514574315771	Andreas Gal — Remove tracking of outer trees and merging of globals since globals will be maintained centrally soon, not attached to trees.
	8e646ea0d669b9d8cbbf2c868417b9d035ea94c7	Andreas Gal — We don't deallocate JIT-related data structures when the JIT is shut down. Add a TODO for this.
	73bb8806ce070943b6573460b913f58ac87985bb	Andreas Gal — Hand the script in when updating the oracle regarding global variable slots even if we don't use it right now. This will be useful for caching information across runtimes.
	2caa960a08a1136cb148bb0918d419dadab32990	Andreas Gal — Use a typedef SlotList instead of Queue<uint16>.
	57b1ef33cc9934faff17e10b1731cb471197803d	Andreas Gal — Teach typemaps how to capture the types of all slots in a slot list.
	6d1976ec3645c423b6d26771021e07fdf5b12f34	Andreas Gal — When merging globals from inner trees to outer trees, make sure to push the expected type upstream as well.
	29b121b064bf4a1426655fac1b30b06447f23438	Andreas Gal — When we trash a tree, we have to trash all outer trees that call it as well.
	3e533b098550327f89cf2f61c3f5d9a81edbee49	Andreas Gal — Recognize loop edges that hit a nested tree.
	3ad06f79570ce9f3806e82c6eae08797de81279d	Andreas Gal — Fix typo (missing memcmp in statement).
	cd85328121b9d81bc4927cdde4ffa4a3955b486c	Andreas Gal — Remove type-map hash code. A direct memcmp seems to be faster (probably some SSE magic behind it in gcc/glibc).
	07a7548b931e08a399446d52ad1d611636782ca7	Andreas Gal — Factor out the code to capture the current stack type map and move around the type map method implementations to make sure they can see the FORALL macros.
	da30b17d58e2758c83aaade678f7a9aea504fef2	Andreas Gal — We expect no interned globals in a new tree. Assert on that.

	d80c57622e6163932f383ebd21cc4ee5887d2154	Andreas Gal — Always trash TreeInfo when we recompile. This avoids the much dreaded JS_ASSERT(insInt32) errors and we can do this now because the demotion information is provided by the oracle and no longer stored in the typemap directly.
	b9e1f4a21962d7d3a4a20662e08a88392b666613	Andreas Gal — Use an oracle to predict when slots are demotable. This allows trashing the TreeInfo* object in the root fragment more aggressively. Rebuild the stack type map at every compile to avert type map mismatches. Purge all global slot info when we re-record a tree.
	c1470ee6849fa0b1791470f550f944f3072c8398	Andreas Gal — If we run into an error during compilation, blacklist that fragment. If we run out of memory, flush the cache.
	919f8fb2ba64c023f63f2d4dcb285654cb80eafe	Brendan Eich — Don't fail to flush cx->thread's JIT cache if JS_THREADSAFE.
	2504d3a10bd5512192a89a3c20ee6f6b99fb2806	Andreas Gal — Flush JIT cache for all contexts. Clear nanojit error state when we start compiling.
	f79dea34edb9568969dfc8f0a1ab4be849a6e359	Andreas Gal — Remove dead code.
	022ae0084f87cd9fb424bffa7175cbb87d144d15	Andreas Gal — Add a helper to flush the JIT code cache (and the fragment lookup quick cache). On a global shape mismatch trash the entire cache (might be a bit overly aggressive). Similary, during GC flush the code cache.
	23c3a6d97ea51d975605778c30649e7038c73909	Andreas Gal — Merge.
	7015dcfa3b822a7f7584d12eaf9b670576d04a46	Andreas Gal — Tracker outer trees for every tree and merge globals of inner trees into all outer trees as we register inner trees with outer trees.

	09a8a075d0c58d981c39f4be0dd58104c52af445	Brendan Eich — Replace bogus assertion with runtime test for correct abort test (getter or setter, given sprop hit from propcache).
	9b0853d93478c05bb5813b7fca85a67abaa36769	Andreas Gal — Fix nonEmptyStack1 test.
	01052828929392217f794650749bf8ca173a4d09	Andreas Gal — Disable outerlining, to be replaced with nesting.
	e16c289f107ffd031878eebf5ba95c8ba70a83b6	Andreas Gal — Add a helper to emit a tree-call into the currently recording trace.

	ba723f04062864c5586975c80f730e6fc03cf187	Andreas Gal — Cleanup stack offset calculation and eliminate the stack offset fiddling that was necessary for nanojit prior to adding the getTop hook.
	134accb72e1db263ce79163789139ac8acb8cf1d	Brendan Eich — Add first non-empty stack testcase, which now passes (yay).
	982fea14d3ad26eb258b8fb25db9698be96930f4	Brendan Eich — Merge again, I lost to Andreas\!

	89624a4b87c3f906925f30c404455274d055be11	Brendan Eich — - Add builtins to support for-in loops, both iterating and getting/setter properties by name using o[i] instead of o.p where i is 'p'.
	e9adc99d55fcb3ab153f71c979c728fc9ccc2912	Andreas Gal — Always trashing the tree on a type mismatch can't work since the first iteration comes in as undefined for loop-outputs and then kills the main tree that deals with the proper stable types. Have to find a different way to deal with this.
	e95d8c0ea2abb676f797122393082cf5ed275b47	Andreas Gal — Pull recompile flag out of the state and pass in as argument. Trash the tree if a secondary trace can't be connected to the loop header. This is very aggressive and might need more tinkering. Trashing the tree on every mismatch doesn't seem to work well, so thats currently disabled.

	d7f9dde8711458d25ab2115be8e6e70692dbd0f0	Brendan Eich — Strength-reduced unsigned modulus in the fragment quick cache, don't use signed % which requires a branch and less-than-zero test.

	01677050142d7b44d16efc6c5af4ec6a880022d7	Andreas Gal — Factor out most of the remaining code in js_LoopEdge into js_RecordTree and move the code to attach new branches into js_ExecuteTree.

	4cc5afb9a89d81281a22be9f6dda37548536d4e3	Brendan Eich — Merge, dammit -- why did we pick hg anyway?

	8c9a97a90e6c1ce851203bf78d2da90a721208d2	Brendan Eich — Backed out changeset 8421b003fb5f -- it broke string to number, demonstrated by running trace-test.js without the -j (jit) option (10 - "1.3" => NaN instead of 8.7).
	d1629f43be3d17bef511fe6e8221e9923ad2a02e	Brendan Eich — Fix ifop null/object inverted logic sense bug.
	0c3e74aa6d88656e9606378834faa01972fbc08f	Brendan Eich — Add \|\| and && tests; use newlines to join pass and fail results now that there are too many tests to be readable joined by commas on one line.

	06fd91141971ad66797e4984ad2b4142d037baa3	Andreas Gal — Make the global frame layout match the slot layout in the global object. This will allow leaving global values in place when switching trees as long both inner and outer tree use the same value.

	578a2ef048ca9f621a4c75d1bd76b20197903224	Andreas Gal — Major shakeup of the interning code for globals. Globals are now detected on demand as they are used and the slots are noted in treeInfo->globalSlots. At the same time the type is recorded in treeInfo->globalTypeMap. The stack type-map is maintained separately in treeInfo->stackTypeMap. All these structures are lists and are maintained as List<T> objects. Imports for globals can appear at the top (if we have already seen some imports for the loop header and are recompiling), or on the fly for lazily found values. We no longer intern all global properties that happen to match a name in the current function, and we also support inlining of functions that touch globals that are not used in the method where the trace started in.
	568235abae0bb152c5841e8a8af9ff27fa5a5f52	Andreas Gal — Use List<T> to maintain global slot list in TreeInfo.
	764fb8d99acf87855e86fdae258283e7247c6333	Andreas Gal — Trash entire tree with all the information associated with it when we have a typemap conflict or the global shape changes.
	494833e3f77e6c68988fb8cce7e8280dc6d38703	Andreas Gal — Remember number of global slots known at that point in the trace in every side exit (forward-looking change to cope with dynamic collection of interned globals.)

	b43051428b55b82175ec6e54995a693aa5dee344	Andreas Gal — Add a generic list data structure and fix side exit handling to always pick the right typemap to work with (exit map, not entry map).

	80fe90ae6f37e4e6dae1ff5567c5169b29374a5d	Brendan Eich — Fix synthesizeFrame's newifp->callerRegs/frame.regs update to pass along the pointer to the precious js_Interpret regs local and update it.
	280c81d5e1e06257a8491fdfe0ebabfd723959d1	Brendan Eich — Try to fix SwitchNativeGlobalFrame, still studying it but these changes seem necessary.

	e1d7528f7744bebf9722b14848e9d1990acc3a8d	Andreas Gal — Track the type of guards and react accordingly if we bail out on them. Guards that protect against out-of-memory conditions don't try to grow the tree. Instead we just resume the interpreter.
	0d41393d023b84be41a9449f73f5ccad7d9bcfc9	Andreas Gal — Don't use ABORT_TRACE outside the recorder.
	980c23ed651ebe7dc13570c42655484296353303	shaver — do setelem in a builtin, so we don't abort trace every 8 times when growing
	7d4d4ed0e52e04cc090ac789e3f09a41a0295fc8	Andreas Gal — If we see a f2i(UnboxDouble) chain, simplify it to UnboxInt32 which does the conversion internally. This also enables a fastpath to read 31-bit jsval integers from arrays.
	ed83a368ff1974b06acb1e3315b58c9309919bf6	Andreas Gal — Merge.
	7eed0be91ce49c924ad8b9b86c0bdb199a411b79	Andreas Gal — Add limited outerlining. Much of this will be subsumed by nested trees.
	f5e9534513710c4f703b3e7b0df98b2fb9311466	shaver — remove rval tracking, since it's no longer necessary
	ee5bf68b0025791cbe4b43a501ed5f9ddeabbe1e	Andreas Gal — Remove guardCount. No longer needed.
	ff7fb1bfd03df2eb976db17bf1fd65e67d53ee30	Andreas Gal — Merge.
	bf4d58f8cc7f728221884369a256f09aadbae20a	Andreas Gal — Smarter speculative demotion of numbers to integers and promotion of the trace seems to require actual doubles. If the number at entry looks like an int we make the slot an int and compile as such. If the loop-tail proves the slot to be a double, we recompile the trace. Currently such miss-speculation cannot be handled on secondary traces since we are currently unable to recompile the primary trace. Such secondary traces are blacklisted.
	543aa57c695af59042969387ba5eff50324c9f8d	Brendan Eich — Pass null instead of &val is no result is wanted by EvaluateString's caller.

	f38fbde81ed186b3880bc39943cf9916c6958156	Andreas Gal — Don't try to demote slots on secondary traces (we have to recompile the primary trace as well for that, which we currently don't do.)
	3bf4ab9ba121c4c876e851a91530728c55bc6305	Andreas Gal — Add a test case for trees.

	12b6d6a31dc735ca1f17806fdf603c8be96e273c	Andreas Gal — Eliminate EntryRegs. Its not safe to keep a reference to the entry SP since we might extend the tree from a different outer stack frame. Instead just store the entryStackDepth.
	3002cb5fd642a43d98535519edf9ee75485b50cc	Andreas Gal — Print real recording point, not entryRegs and add an assert that makes sure the guard we come out of is associated with the tree we entered into.

	ff036e43274007e1bad6e9d2634b08368f74c831	Andreas Gal — The VP engineering broke JSOP_NAME! We have to check whether the slot is actually interned and otherwise abort.
	c2f49e1a25942d9b9ae9fe54f7a344c5da466d8b	Brendan Eich — Avoid JSOP_POPV in global scripts from load(), etc.
	fd9cf3c556ee0d410dc934be71956a0d33271d2c	David Anderson — Fixed entry typemap having wrong allocation size.
	75805867814e6e819ba7508a20ffd01dc126b55e	Andreas Gal — Can't use lr->from. Seems to not get set in certain cases. Go figure. The nanojit tree code is really weird.
	f5149a2b93091409dc28978c5c29cd00460188d3	Andreas Gal — Factor out AttemptToGrowTree.
	2666adaeb7527e7eeda8ce1c2db9cd1ed7ccc85d	Andreas Gal — Determine ahead of time whether a side exit is a loop-terminating side exit instead of re-determining this at every side exit.
	650ff18ef51f6c436528cff2b72d721e30f41f18	Andreas Gal — Move trace activation code into js_ExecuteTree().
	8809b9fffa2749035f47cbfeccaacc40b27e4168	Andreas Gal — Make demotion threshold optional (0=off, 32=default). Turn off to debug the type assert bug.
	81375d2214942696bc81f38b1de872085fad105b	Andreas Gal — Don't demote slots in overly long traces (based on counting the number of guards, current threshold=32).
	6747a00cdc2c2d82c1fe8c459222afdad7625920	Andreas Gal — Cleanup iteration over all slots to use a single macro to avoid code duplication.
	d4612c4b9cc2a504016021b7635d36acbb7640ba	Andreas Gal — Add shark support to md5.js directly, no longer around the recorder.
	d9a55e3014f88e9f9242010c933ffc93c0994e70	Andreas Gal — Make the interpreter notify us when frames are popped so we see he right cx->fp value. Fix return value tracking for JSOP_STOP.
	d0b29a253c221f211cf45c5bd17ab49632a2e30b	Andreas Gal — Backed out changeset a58e7ce6eb7f. stack(0) is wrong, if at all it should have been stack(-(1 + argc)). But anyway, its impossible to write through to the frame via set() at that point because leaveFrame() doesn't actually modify cx->fp. We need to wait for the interpreter to do so. Until then nativeFrameOffset produces incorrect values and the assert fails in set.
	a58e7ce6eb7f1dc53de70c13b9707d4799f331aa	shaver — fix return-value handling for new stack layout

	1fa3e45f253a841ccdfee21c062b082919f236f2	Andreas Gal — Add a fast path for nativeFrameOffset that walks entire groups at a time, not slots. Check against the result calculated by the FORALL macro in DEBUG builds (for sanity).
	c1d3d1e0e92418c474a374bcc876aa8845fdb00b	Andreas Gal — Merge. Make sure we clear out all slots from the tracker when leaving a frame.
	7f3cc9a4bf1a39d823ef4f1a3bcbc8ecafe0553e	Andreas Gal — When addressing locations above the stack water level, use ->sp as base. Shaver accidently changed this to ->spbase when merging Igor's patch, so we were writing past the water mark and the stores were killed.
	711092884c032410bd635b1d68ef9c778afa3777	Andreas Gal — Lazy fill the stackTracker as we lookup the nativeFrameOffset for values. Purge all entries related to the current frame when it is popped. This code could be further simplified if Tracker was a template.

	3a9f641607b8688ff5016c41370c9ce8a5103a13	shaver — use nargs rather than argc, since bytecode only refers to [o-nargs) args
	19b10d2f8e770f848cf327aa24704944c80f396a	shaver — make time.sh more useful

	84567cee23affc704315debffa48ab8d7b12ddaa	Andreas Gal — Eliminate entryFrame pointer (not safe to carry that around.)

	62a1e92eea54cb7e04f05b9f7c9882dc7b87e302	Andreas Gal — Write all the debug output to stdout (we can't easily make everything go to stderr, so this way at least it all goes into the same place.)
	0998e027bc956f107e0f168c3aa5a1acde461ae8	Andreas Gal — Rework some of David's changes. Make sure we don't modify the tree until we are ready to attach the new fragment. Share lirbufs between tree branches.

	2782087a069d9f135ebafbaacf88cc0b7e6e7e32	Andreas Gal — Add md5.js so we can play with it. We should sweep these test cases into a subdir or just delete them once they trace.

	2e157a7a4bcd328abbd737af36522d27f4fcbd69	Andreas Gal — Don't intern global function objects onto the native frame since we rarely ever need them anyway (we call them via the property cache).

	177105a57dbcacf7e9c815b1b6c20fae42dc6468	shaver — more ABORT_TRACE instrumentation (some should be asserts?)
	343491f8a45469dab381fd58c24658763df39e0e	Andreas Gal — Generate a list of interned global slots (gslots) when we process the tree header. This list is then used whenever we iterate over the native frame. This is faster and safer than looking up properties in the global object every time.

	120f4016b20dea3104cb69dcec6a0d1715ec4747	Andreas Gal — Added a callstack that will track the pc of the call that caused a function call to be inlined. This is necessary to recover from deep side exits inside inline functions. The callstack is subject to store elimination, so unnecessary stores to the stack will go dead automatically during compilation (i.e. if we inline a function that doesn't have side exits.)
	ee36097ea0b5071301bdd8dc6d3b08a184991c90	Andreas Gal — Fix warnings.
	14f0ea38fac42068e461932ef0c704b5e83bfb83	Andreas Gal — Use JS_GetGlobalForObject to get the global object. Walking back the call chain is not equivalent and not safe.

	1383b5e65a1945d5d729d798b122e8e2f3540e70	Andreas Gal — 5 hours of debugging, and 9 keystrokes to fix it. That was one expensive bug. shaver's reduced fannkuch example works now. I think independently of this one we don't check properly for index underflow in dense arrays. Shaver is going to have to take a look at that (this fix makes fannkuch indexes not become negative, but doesn't explain why we crash so hard if they do become negative).
	b794ecae165364e7bb0a156a65b9ba3660e48fd7	shaver — add JSOP_NEG and tests
	478add19377d5715175f4ef6ef9edab090067f8c	shaver — add Math.cos and Math.pow to the specialized-call party, and add tests

	efc04cf7a7c24573ed120dd75bdcd69d85513018	Brendan Eich — Nits: avoid (double-)over-parenthesization, underhang extra args to start in same column as first.

	f81e3afa991b474f55b8d3811bff4f4829bad758	Andreas Gal — Don't demote u2f conversions and sink the type cast into the side exit type map, because this loses the sign bit for unsigned values. We could fix this by adding an explicit unsigned type to the map, but for now I think we should stick to int/double only since there is the risk of fanning out trees. Crypto doesn't seem to use ush all that much so we should be ok performance-wise.

	7aa4c0495595b4a356223de19d77c7dee376ec5a	Andreas Gal — Housekeeping. Remove a few warnings during BUILT_OPT and spelling in comments.
	470d9a1d268c82e51d06e5c61dc3896c0348c234	Andreas Gal — sp_adj is now maintained in bytes, not words, so +8 is now the magic value to point to the top of the stack. All stores above that watermark are eliminated by StackFilter in nanojit.
	4f7491dea3d2920ac7dcbcaff07dc0716fa8c65d	Andreas Gal — Merge.
	02c0d6e2fd17e1de5d3d6f2a6be94a6739a04e64	Andreas Gal — Removed bogus debug printfs.

	edfbea1e9a8375ae6c10e0a0e65b85192cb37f4c	Andreas Gal — Fixed frame walking FORALL_PENDING_FRAME_SLOTS and add 4 to sp in getTop (hotfix, not the right way to do it.)
	fd75b6874a9cec8d619af43e76ee928de1af5c9e	Andreas Gal — Merge.
	71d55866ed34587bb07579ed89c4cf027147ab32	Andreas Gal — Use more efficient address mode for LIR_load if possible and removed bogus printf.

	1dd22bd88472936afb0e2bf45bf9b2850244ee2c	David Anderson — Builds against latest nanojit; merged VMSideExitInfo into SideExit
	842d94f41381b26c8e05d8fdbbc9f8a7c168cbdc	David Anderson — Merged with tamarin-tracing (Moved SideExit and GuardRecord out of nanojit, improved labelling)
	7d2e28b8fc80b562496e070750421e7b0a5cb215	Andreas Gal — Fixed argv[n] and vars[n], should be [0] of course.
	eeec9337de5e49c86806fd8959d887681cccdb71	Andreas Gal — Add dummy vpname/vpnum parameters when not compiling in DEBUG mode.
	1eecbfbdbd3c3722b38b727345e1eac82bec918d	Andreas Gal — Merge.
	99c4184cbf34330ff0a920276fcdbea3eacd8cf5	Andreas Gal — Introduce a generic stack frame walking macro. This eliminates the 6 (hg pull) redundant blocks of code that all walked the stack in 6 different ways, each with their individuals quirks.
	58a616473add75962dc7c51bcd43098f2afa3b29	Andreas Gal — Don't check the types for invalid global slots in checkType. Proper gvar lookup in boxing path. We have to unify the stack frame traversal and enumeration code. I fixed this bug before, just in a different place. 11x speedup for gvar.js
	2b29b2099f3d3b6c86f6f77ec0319f597b3d7e4b	shaver — root converted argv[0]
	7c4145294a0134cea8335b27e5e8aa6fffeb373a	shaver — Add disfile() helper to debug shell, to make it easier to see disassembly of top-level scripts.
	a8b3db0a4599d3c7d5132db9bfcaadc1bcb91945	Andreas Gal — Properly display the 'any' type in the side exit map printout.
	4725b1f18ea5cbabaec76e5ea6068285c0eff9d8	Andreas Gal — Cleanup definition of tracker (don't use LInsp, use T, its a template now).
	167f648e1919b666d0b95782db22b85e0e738074	Andreas Gal — Hack: demotable stores have to be flagged as int in the exit typemap. This needs cleanup.
	56aecd44a8d847444b488d5b5df9da55505db943	Andreas Gal — Don't expect args and vars in a top-level frame that is mapped to the native frame.
	0237d5b48ae816d6de282e220e924cb503f21c93	Andreas Gal — Merge.
	1ac351d69a1ecf85362bca01f5e12b8b7d3ff2d3	Andreas Gal — Fixed native frame offset calculation for globals.

	f68f372c47f93c97b0973752b8aa9b95e90d6e42	shaver — more detailed type-instability diagnostics
	8da113260e1e4aa0b3f28a6331ba802e5d5713bd	Andreas Gal — We urgently need shaver's magic native stack/typeframe iterator. Fixed exit map builder to skip argv/vars for global scope.
	92637c19d98668594728563820b66eb26afbb304	Andreas Gal — Fixed increment for DECGVAR.
	c3dd9d7d727ff402b5a4dcbfc525473807e0ed2f	Andreas Gal — Bugfixes to the native stack and typemap handling code.
	cb4443f6f55d178eb07524a8a6435b3ed4554c78	Andreas Gal — Attempt at cleaning up the typemap/stack frame iteration code.
	3a2b7c4ec50e2841d0611c4103a841a68e7ced45	Andreas Gal — ngvars and the slot index are not related, so don't rely on ngvars < JS_INITIAL_NSLOTS to decide whether dslots exists
	feb147abff3e52c502d3564350034f42c8c7bfcd	Andreas Gal — Make gvar ops use the global varobj values we unbox onto the native stack. The stack offset handling needs more work.
	20f73d36a25a8cbe84c14982d9c6dff11501974f	Andreas Gal — We shouldn't read globals onto the stack if the global object is used by another context so we just refuse to execute the trace in this case.
	f72ce8842a04fa9600a8764fe574526ee822a8fb	Andreas Gal — Unbox global variables onto the native stack and re-box them. This has certain synchronization implications but will make top-level scripts quite a bit faster.
	c7fd31cf2ac8c0b29810343ba362a823ca13385e	Andreas Gal — Don't try to demote a slot we already decided we can't demote. Also, make sure we only demote additions with constants where the constant fits into an int.
	d1b0469a1f5d3eb4bae832a0a6ef2986bdfe5616	Andreas Gal — Merge.
	7716f42de1f01bb8840b51b13e9058a1eaa4f2cb	Andreas Gal — Removed an unused variable from the avmplus glue code.

	28ee0944d8703c00d9208c19dd498a0bd552151e	Brendan Eich — Indentation and comment wrapping (at 79, 99 looks too long and most comments still avoid going past 80+/-).
	bc67eb0d7e8aa947e4549b5c352fc43646f93461	Andreas Gal — Merge.
	23d317c80d00330484a91f6bbc5afbc95fe3a588	Andreas Gal — Sync nanojit with tamarin-tracing tip.
	5b4529458a560d4fabcb625f3eaadd23bb151c39	*Brendan Eich — Use jsopcode.tbl for tracer JSOP_ method decls; trim trailing whitespace.**
	1aa7e11366a29c3fe26fed7639e140ead5ab5902	Andreas Gal — Cleanup the native frame -> interpreter frame boxing code. We sometimes end up with numbers on our stack in double format that are really ints. We have to detect those and properly store them as in on the interpreter stack.
	d88a5e56ec9382799f89b9a87d8b4f9a561ff1af	Andreas Gal — Add support to demote stores of constants that are currently represented as float but are really integers. bitwise.js is now compiled complete fp-casts free.
	0f7c4afcd5c83af511ec58c8798e0a4716524f96	Andreas Gal — Demote floating point comparisons even if one side is constant (bug in nanojit, filed as #443884 against tamarin). Also demote add/sub/mul using the integer overflow detection side exit code that Ed adopted upstream. Tight loops (bitwise) are not emitted completely as integer code after the initial compilation using doubles triggered a speculative demotion of the context slots.
	a051c0844e1ba0b0127db7aeccebebd09222e781	Andreas Gal — Sink type conversions into the side exit by updating the map and seeing though the cast in the store (in ExitFilter). Add a whole bunch of asserts on the varios speculative type states to make sure we get the state machine right. Import speculated integer values as integers into the trace (indicate in entry map).
	d268132c1bf643d4f98d139a5444468bbd87e5ee	Andreas Gal — Added loop-tail driven context slot type demotion. Without all the buzzwords, what this essentially means is that we detect if the last value that the trace leaves in a slot (which is the value that flows along the backedge back to the loop header) is known to originate from an integer value via i2f, we flag the slot as type integer and recompile the trace. We do this where type stability is certain (result of an and, i.e.) or where its very likely (++operator). If the speculation fails, the same analysis flags the slot as blocked, which means it will always be double. The hope is that this analysis converges quickly (1-2 recompilations tops).
	7f3e0b5b05dd1e749b772a6ca4357262b48b46eb	Andreas Gal — Make sure we don't get the argument order in BoxDouble wrong again.
	c3568285ff19a11ee557006da9b8e70553e69267	Andreas Gal — Make typemap uint8_t and fix order of arguments in call to BoxDouble.
	ce35d7c30a31f407fc779c1c40cc779c6b7e1b90	shaver — remove outdated guard (now inferred via filter as needed)
	513b636c199b467c3164ea1fbb319d0e6e84ad95	shaver — we only speak double around here now
	37dd888fcb4252ce63619cba74722c6640fe0154	shaver — remove bogus NOT_REACHED
	fdab515b3c8acd9f82177744961a47262e627aa9	Andreas Gal — Strength reduce i2f(doubleToInt32(x)) and u2f(doubleToUint32(x)) to x. This eliminate most of the on-trace overhead, but we still need type peeling of loop variable into int to win back the performance loss casting introduced.
	f6179396df600b85b1b6cda53ee18db24fa06576	Andreas Gal — Reduce redundant doubleToInt32(i2f(x)) chains to simply x.
	0b810d0bf2e7572dbc69b66fce1c3a8b323560bf	Andreas Gal — Strength reduce BoxDouble(i2f(x)) to BoxInt32(x). Make sure loop indexes are actually integers. This guard will be eliminated further down in the pipeline if we decided to peel the type of the loop variable (index) down to integer.
	5ebea36d79ade1ab78789c7d79a0bbb3fbfeb1cf	Andreas Gal — Since numbers are now always represented by doubles at the recorder/type level, using BoxDouble and UnboxDouble only when moving numbers from or to memory. A filter will then turn f2i(UnboxDouble) into UnboxInt where appropriate.
	8374e34d597e56684f05628edb4f5c0bf8752e44	Andreas Gal — Move the type level from int/double to number. All traces start out as double in all slots, and denote and promote to/from int as needed. The FuncFilter optimizes on-trace casting and elininates redundant f->i-> chains. More optimization needed on this of course, and this code is now a bit slower than the previous integer-register use. However, this does solve the q += 2.5 issues. The heap access code does not properly cast yet and is likely unstable.
	360a6ce57d28f76b5f739770c81c1d0ff57926ce	shaver — Trace GETGVAR and INCGVAR, though not yet correctly.
	d84c7e0344ed2c6bd7c28ba6a3eb286558c490e4	Andreas Gal — Add unary and binary helpers that automatically demote and promote when dealing with integer operations (not used yet, need loop typemap peeling in place first.)
	8e62c283774efb8a96b0d6e0aa9043f71061a69a	Andreas Gal — JSVAL_IS_BOOLEAN does what isTrueOrFalse was trying to do.
	0ce416b5a3df5c324d78859a3d91ddf78678a3b5	Andreas Gal — Fix template, should use typename, not class.
	f89cf130bd52037f006c1b950abfebe0e1c6df7f	Andreas Gal — Add ExitFilter, which builds side exit typemaps for us. This had to be moved into a filter, because this has to happen after we eliminate redundant i2f-f2i chains as we can sink those into the side exit by simply storing the unpromoted/undemoted value and just flip the type in the exit map.
	fcd3450f9272bba03d987ed0fe90040c2253a801	Andreas Gal — Merge.
	a53c3daea0e8bce5abd06e13a810b60177cf5ba5	Andreas Gal — Added doubleToUint32 builtin and make tracker a template.
	a2e3ea92df6516cb0f4f4f0dd04f49ee0cba5218	shaver — fix builtin_UnboxInt32 signature and name shape_ins for debugging
	ba845ab9dff1c7f57f002bd5de9a3a247b43b15e	shaver — Trace JSOP_NAME, and refactor out jsval unboxing.
	b83911cb6d173cd2e7300554810276c3bfccebc1	shaver — begin on JSOP_NAME, refactor stobj_get_slot to chain better
	2e8512ba0fb481206e3f7d5850888bd370ee7f37	shaver — Fix optimizer flags for interp and builtins in debug mode, and clean out old
	e9367ede4167ffedad12590489df214df230dd24	shaver — actually record at HOTLOOP1 (fencepost)
	f4cec2d38f041826b410393e653496db3efa2e31	shaver — some remaining low-hanging ops
	e4fae864396eb19a24de8d3c48fd9bfe3fe01a17	shaver — move JSOP_DOUBLE impl to, er, JSOP_DOUBLE (wtf?)
	6b5d40cc17fed5881b74cf387a56cf121a8ae22a	shaver — Implement JSOP_DOUBLE.
	859e409ef3796a8abd3e636595d06bb481e4d13d	Andreas Gal — Added support for semi-stable loop variables. Compiling for(...) q += 2.5; is ridiculously difficult because it flip-flops between int and double. Add support to promote integer values to doubles at the loop tail if at loop entry we expect a double. Since this isn't possible the other way around, we have to get luck that we catch a path into the loop where q is already double. For this we add 3 trigger points (10, 13, 37). We will try three times to record a trace at those iteration counts of a loop. If none succeed the loop is blacklisted. This probably needs more tuning down the road.
	774553375994ae0990e57d95af34880e8fc6b67f	Andreas Gal — Merge and rename jsIf to ifop.
	6ab468ffe7f4b34721667d3eb85259d037f9eeca	Andreas Gal — Added FuncFilter from tamarin core (not part of nanojit yet since its slightly VM dependant).
	b5556367172da3d22140e614f878a8c05eee47fa	Andreas Gal — Add helpers for i->f and f->i conversion. The f->i path goes via builtin calls.
	46aabcce02752fce4ae10eda1cfc9a6371337474	Andreas Gal — Add type primitives for numbers (isNumber and asNumber).
	8bff19dbf023f7acfb312941c8ccb149d1c4f388	shaver — Implement JSOP_IFEQ, JSOP_IFNE, JSOP_DUP, JSOP_DUP2.
	3d66327238969be22f6d92dfca5fa7bde24dc8af	Andreas Gal — Add casting for objects and cleanup casting code.
	b1d8fd0005e9ce0d1d0387ad1f2a2122d19bf336	shaver — let JSOP_GETELEM handle boolean values too
	6272876588dca9a03a207db551c0d1104c56df6c	shaver — Handle boolean lval in SETELEM; now runs access-nsieve unmodified.
	355d79be4adfe120ebcb0ee2f61ee463106f10e5	Andreas Gal — Believe it or not NEG can actually overflow the int32 range, so add an overflow bailout. This will only trap for -0x80000000.
	f4c96a566c4c826d41a6249d784b90e465c66cff	Andreas Gal — Merge.
	138fc2d7f4fe744306e5244549030edfb3d9469c	Andreas Gal — Added blacklisting of recording points where we failed to complete a trace (overly aggressive at this point, needs tuning, we want to try several times for each point.)
	1a4d440c60e4d2dbc9fd3c6c50ab7c9dc6e0b0b7	shaver — Allow hole-filling JSOP_SETELEM to remain on trace.
	04f3c8fdf238f14566efd1fa27c716d3e486c4d8	Andreas Gal — Fixed boolean boxing.
	0523b54c86d82a7aa4dc531290557630c07a4c70	Andreas Gal — Added boolean boxing/unboxing code.
	e3af49ee7476edbcc11fab2097190f52c66933e9	Andreas Gal — Use default parameter in LSH/RSH/URSH to indicate we don't care for the overflow.
	d23078399de1315e772b009814d1680b3edc51dc	Andreas Gal — Added missing jsbuiltins.cpp
	6ffdcbdb066c1963380a2e12e4e99f601da2f8ba	Andreas Gal — Add support for some misc opcodes including binary and arithmetic and/or/not.
	639f37f76fa0a16a05e95a5b05c2fb81026914a5	Andreas Gal — Track trace entry/exit in debug mode and count cycles.
	f5a30a112d06eacf7a701fcf27123fd4907e97cf	Andreas Gal — Signal error from the boxing/unboxing using magic cookies since gcc seems to very seriously object to the use of uint64 return values during a fastcall (horribly inefficient code).
	8c6d36837b228e0b633f5e0dbc9cfaa01ad7f798	Andreas Gal — Help the branch predictor in the builtins.
	9edc74143be669124e0589c0636e026bd9d7519b	shaver — use FASTCALL for builtins
	ac9c1fa73e6f3abb9bd736025dfbdaaf3652c400	Andreas Gal — Style nitpicking. Fix overlong lines.
	c0ee4caf332f33b3e992a3e7087b2e874edee87c	Andreas Gal — Finish SETELEM for int and double values.
	977464d95d02128f8a5071cb41c4d5518ea48e41	Andreas Gal — Merge unboxing code into GETELEM code.
	788d1cebba153024a3dd5f932495339fa6d888ae	Andreas Gal — Merge.
	7169fbc897a32d8410568ec93460ce95169b6110	Andreas Gal — Added box_int_jsval for the store path. Use only there.
	95a5982008b78be8159ce522ace431691f2d4160	Andreas Gal — Code generators to access object slots and native code callouts (builtins) for boxing doubles and ints. Ints have to be boxed through a native code helper on read and write (BoxInt32 and UnboxInt32), because we sometimes have to cast internally to double to store 32-bit values. We don't want a separate trace in this case, so we have to do this inline in a helper. Also a couple of modifications to shaver's code. Always make sure to check types (JSOP_NEG).
	84e68fc5d54329770eaa6f12c3c0801cb65a3be4	Brendan Eich — Fix dumb bugs I just committed, use JS_NOT_REACHED.
	a03f8c8930e6ddabfc4b8828ac9cd2d94983dccf	Brendan Eich — Try to keep 64-bit portability via size_t instead of unsigned, jsuword for uintptr instead of long, etc.
	c527aa0c12110e8a28723197be273bc57926fbff	Brendan Eich — Spacing and comment nits picked while reading.

	2938be7b4c93504ef22e0995ac16653ce48d599a	shaver — merge
	719aa82700052a12d95339d328e26fb680571745	shaver — [mq]: simple-ops
	4fcf7c5ee2fc7f8acf0817b02bea55cf4c39ec9c	Andreas Gal — Introduce asInt and asDouble to check for the type of values based on the actual value since some 32-bit integers hide out in doubles.
	03f3750f7a9891cafa60864f57e5c1716957ffff	Andreas Gal — Make trace-code 32-bit clean and extend interpreter state to carry the current context (cx). The recorder still has to record a 31-bit int path through the loop, but the emitted code is able to stay in the tree even if values bump over to 32-bit ints.
	10f55a9db85b57ff6aeaab930f82b8e7f8684f05	Andreas Gal — Added support for SET_VAR again. bitwise.js working now.
	6a5ca2340d494d1bff1b36763f68c7e78a471275	Andreas Gal — Fixed some stack handling and trace activation issues. We can run trace.js again.
	ae9f7adc0762254128de1a62b38617935dd9e589	Andreas Gal — Cleanup of stack handling.
	db124a3fb5a5ed207ec9e63188b287d04dc8659f	Andreas Gal — Added back support for the instructions required to compile trace.js.
	9c29b510c584784de3902c4f65b2db17fc02186f	Andreas Gal — Properly switch tracer on and off depending on loopEdge and abort signaling from trace recorder recording functions.
	4b9461f0261837ead4a427bf3b040ef3c7ff23d2	Andreas Gal — Re-integrate trace recording and trace activation infrastructure. Model more closely after Tamarin.
	34fa1af7848bb5ccde5d83efebc955e9311c47d5	Andreas Gal — Create a stub for each opcode in TraceRecorder and invoke them from the stubs that are pointed to by the recorder dispatch-table.
	401bf43ab0cea67c387d57e4c70522a33f147bef	Andreas Gal — Extend dispatch table to include 256 extra cases for traceing.
	5192699cc8d8aac0de2a67746f6e330df58139ed	Andreas Gal — Switch back to mozilla-central jsinter.cpp. Lets try a different approach to attach the tracer to the interpreter.
	7e5d184d4d0aaa126293f3b0b0da534d218a8498	Andreas Gal — Sync with mozilla-central.
	2bf9378f3362c194415b081e1c13b6ff10e53951	Andreas Gal — Avoid name clash between nanojit and jsinter.cpp (full patch queued up for tamarin).

	5b8512aeaa740c7d886c0bc7abd3aba6c7b5d10f	Andreas Gal — Added dmod builtin and flag broken builtins for removal (shaver).
	00d6535c9a737ca66d96a967e544a3f995660d71	Andreas Gal — Support recording of ValueToECMAInt32, ValueToECMAUint32 and ValueToBoolean.
	d5da6f30023ce6a7128c691fa2ef31cfcdcd5e87	Andreas Gal — VOIDs hang out in the BOOLEAN value space, so we have to treat them like a boolean on the trace. For ValuetoECMAInt32 all special boolean values except TRUE produce 0, and TRUE produces 1. Use a conditional move to implement this.
	f6e82eedc29d2d5d231452f0affabe0272402a69	Andreas Gal — Introduce a VMSideExitInfo structure (holds the exit typemap only for now).
	0c8bf263ee1cd14f1e87b01a7c0e260911570412	Andreas Gal — Fix returning from trace execution into the interpreter.

	ff52c714902a2d8caeec722eb4408ba2739f2fee	Andreas Gal — Use fragmento to track fragments and add proper trace activiation code.
	ea4d2030913b7b0ae8f2685b8cd80e59a248a440	Andreas Gal — Fix unstable trace rejection for optimized build.

	99ea7b7fbf40404983f2a5972ac6159e9e4ab46e	Andreas Gal — Add type stability check for loop variables. Rename readstack to import.
	ac906d2bd9407662524b8230116f93b09dc99ea0	Andreas Gal — Removed attempt to imply ints into doubles on the fly. This can't work. Use proper float loads where needed and add some initial code for builtin functions.
	e5752cd92d9f396dc02d1ff547997b4297761f0d	Andreas Gal — Add a vmprivate field to the guard record (queued for review upstream).
	8a001f939bd31f8c4d2b42a7e72310f0e48a531c	Andreas Gal — Indicated in a separate primitive when integers get stored as a double because they don't into a jsval.
	44bce227ed5d3dcfd9bec3faefef49da244e33c0	Andreas Gal — Backed out changeset 745089a5d1c5
	745089a5d1c5a739d7fbb5db98d1b21daee20846	shaver — no need for rooting of integer values
	c512cf1203274108a302e72a92fcf4c643216578	Andreas Gal — This patch eliminates ValueToECMAInt32 and instead tries to emit specialized code depending on the true type. 32-bit integers are detected and treated like integers in fetch_int via ValueToECMA32. Similarly, int store_int NewIntInRootedValue is used if the value is really an underlying int. NewIntInRootedValue is a nop on the trace.
	b5d17a5c464ab650347de7cf8d7417151f36fd22	Andreas Gal — Flag ints as type INT in the incoming context if its merely a double holding an int that was too large to fit into jsval directly. Along the side exits make sure we can properly box oversized ints (by casting them to doubles). The fetch_int/store_int paths still need fixing to ensure that values are merely passed through (prim_copy) instead of explicit casting or calling to ValueToECMAInt32 etc.
	363464372fc4116f68cf4255c1f38ae2f361f5a4	Andreas Gal — Don't allocate 16MB code cache at startup. Instead use an exponentially increasing growth factor.
	6d437a2b583246812137955d086e64824fe72bb2	Andreas Gal — Generate proper overflow detection code. Requires a trivial fix in nanojit (included, pending review to be pushed upstream).

	5593833365c9d05bd35482be801b158b5805a98d	Andreas Gal — Create type maps during trace entry and in each side exit and store them in the LIR using LIR_skip. Use these type maps during trace entry and exit.
	e5cb0d24cb731bc630120bf11f78a170c7ffc0e1	shaver — beginning of trace-capability regression minisuite; will crash you today!

	6e00e0f31c560dfb46d1bfa3fc43957524659d39	Andreas Gal — Fix deallocation bug in the recorder. We will have to lift more code Tamarin's Interpreter to stabilize the recording.
	698856edc137f6c58f8958c8dd0dc5321b12bd5a	Andreas Gal — Better naming (MARK_EXIT => MARK_REGS).
	46d4b17463d41588a03c9c2bb6ccf0994448a3e1	shaver — Assembler requires that guard be on a cmp, so force that
	45c643b522a6862dab4200014a7a38379b186db7	shaver — fix frame offset calculation for args, I think also non-entry frames
	01359d7a668ae26e5c583865318ebf3829e5d573	shaver — label arg/var/stack/sp/state for easier trace-reading
	df77fa4a3e5b743829926413ec8cb47eadad2a55	Andreas Gal — Save the VM registers into markRegs at opcode entry and restore that state when ending or aborting recording. The same info is pushed into sideexit and used by guards. With this change we can eliminate the hack in MONITOR_BRANCH that had to adjust the stack pointer depending on the opcode type, and it also allows us to trace through the recently added boolean guard opcode fusing. This improves trace code quality, since only the pre-conditional check state is saved. The guard restores into that state, so the trace code doesn't have to emit the value of the conditional evaluation onto the stack, saving a handful ops.
	30a18c0f363b7afc9e8b97dafcb06d43433c172e	Andreas Gal — Rework memory management, don't leak memory in the filter pipeline.
	3dcda8cce1d7913534236f9496e44bf38179a013	Andreas Gal — Save the side exit state at entry in to the opcode (since we want to restart ops) and enable store filter.

	fbb073357c595f8a9eebbc3380a4fd6d89c2bc16	Andreas Gal — Mockup of trace execution. Speedup is 10x for a tight loop. Keep in mind that this is a hack and the trace code is not optimized yet.
	676e746becda45cd99a64d7fef758fe7bf1fed2b	Andreas Gal — Execute trace code. Boxing back the side exit state is not handled yet.

	77cc23e2d53c734ad6caa9602caab8686e94b572	Andreas Gal — When a conditional branch instructions terminates the trace, we have to make sure its restartable, so put the conditional value it was deciding on back onto the stack by incrementing sp before jumping back to the outer interpreter.
	5e199f65bd2485f5a65cff2eea530a7ab1965470	Andreas Gal — Initialize jump table when side-entering the interpreter. Keep track of cx and sp directly in the recorder instead of going through the tracker.
	52a27edd2802d137aa7a4e42a7abc0cf4dc7c37f	Andreas Gal — Guard inside the clause, not seperately.
	2a09d92140a0334e4de9d22c775e11b908355d12	shaver — guard on inlined branch in TRY_BRANCH_AFTER_COND

	6fec9157a4067cd04cacc2ebd1301befc5953a5f	Andreas Gal — Mork work on attaching nanojit to our primitives. Traces have now their own box type (Box), which is an opaque 64-bit value. Its never supposed to appear in the trace since we will optimize away all boxing operations.
	a7edb7cd3362cbe28a01a2a7b4ecb43c41309f48	Andreas Gal — Start attaching our tracer to nanojit. This is incomplete and meant for review by David only.

	75910f31ff657d39f3a5fe3d47d7e4608988f335	Andreas Gal — Call into the recorder for each primitive. Don't use vp in primitives, use &v instead.
	341346bb54372758d29e6f138c94860aac309748	Andreas Gal — Notify the recorder of all primitives as they are recorded. If the recorder doesn't support a primitive we abort the trace. In debugging mode this also stops the VM.
	91ba153e72f96ae50f06883caf45c354bcce088a	Andreas Gal — Merge with be's last push.
	bad02ba8aee9f8bd71912b71b43775a2639224df	Brendan Eich — native_pointer_to_jsval should not lose low-order bits (plus random style nits).
	d2a74e1507aefc9765fcfbc9dfe0fca2628d2bbf	Andreas Gal — Initialize ok to true if we didn't side-enter via state.
	f89e1b7fafa762cbbd5370ef2448a25ba2c0c74d	Andreas Gal — Use an error property in the recorder instead of a return value to indicate errors and make sure DO_OP aborts the trace once we go into the error state in the tracer.
	a13ba208e5096773ddb61ce90ef5acff73a8a823	Andreas Gal — js_CallRecorder has no return value any more.
	7fd3d9c74652ac914943612548b47b0d1a2142c0	Andreas Gal — Track data flow through variables in the recorder. Set an error flag if the recorder signals an error.

	ae95e4bcd0bfe911096cda5d74488fa0dcc74e45	Andreas Gal — Notify recorder when tracing starts/stops. Restore code accidently lost during last merge.
	2981e86cc0d723020df5a481c5d3dc2bba43d603	Andreas Gal — Connect tracer with the interpreter. Errors and exits are handled in the main interpreter.
	ed2e73551ac7b475c8366f0343797ef9df9791e5	Andreas Gal — Merged with Brendan's changes.
	2eadd3630e4c926e1a7c17f7e0a561dd29735f7f	Brendan Eich — No need for eval call.

	e1a6be3a3f98c679501def18e4480d956626df5d	Andreas Gal — Added code to switch to the tracer and back. Incomplete and for review only.
	b4c57593abb2dc9102b631725b5e7c96e60defdd	Brendan Eich — Style nits, plus no need for rt in JSInterpreterState.
	0003fed8f30b2d98ad2fad0d68fe8e89359c2b02	Andreas Gal — Create a side-entry path into the interpreter that bypasses the initialization code and allows switching back and forth between two interpreters (i.e. tracing and non-tracing).
	9b83fbc282d08c30e1c35d3bbae1afb89304f2b3	Andreas Gal — Added branch monitoring using a single unified branch frequency counter.
	ec3574da400646bdbfe5b5b376c4c52818d18334	Andreas Gal — Removed JSOP_HEADER code. Its too costly. This patch restore essentially the same performance as unmodified SM.
	37976bfa3bf526de3767ccfeb37002358fe0fbbd	Andreas Gal — Disable JSOP_HEADER counting.

	783ab3f4f488fb54bf50ccb6a7ac424c4217f84f	Brendan Eich — Merge.
	39fddc89d6c7646ec1742f2264ca113ab21d5e38	Brendan Eich — First stage of loop table work; bitmap free space management and GC hook-up still to come.
	15fb0c1efd77e38d1499822ab500e8169ceaec01	Brendan Eich — Fix decompiler (hack, really) to cope with misplaced JSOP_HEADER in update part of for(;;) loop.
	bee80ed3540fd4086a0b8d59691c87dfab774639	Brendan Eich — Merge, simplify names, and police style.
	48ffc3e5564b38c2e67a12f5b9889acd91bee787	Brendan Eich — JSOP_HEADER takes a byte index of loop header counting from script->loopBase, and related changes.
	82fcc97a2c99dae4f628b11bd2d7f938cd315c7e	Brendan Eich — Fix ReconstructPCStack oplen code, extend js_OpLength to avoid cs recalculation where possible.

	a35cf568c2f12b06c38863a546ea29cbb9df325e	Andreas Gal — Store the recorder script in JSTraceMonitor and make sure its traced by the GC. Also clean up the tracing of JSTraceMonitor.
	855d3dd9f89581f3bfdb2aac7a81264ff6523cef	Andreas Gal — Backed out previous attempt to find a place to stash the recorder script.
	159f25b5b55290dbdd963bb4bf95aa27ca9ddb50	Andreas Gal — Backed out changeset 3029f4d57bd2
	f40c6d08bbc5f891c4dabd80fbb39a36af655ffd	Andreas Gal — Switch to a uniform style for jstracer.cpp.
	3029f4d57bd20990dd25434b89d552da4850975e	Andreas Gal — Add location in the context where we can hold the recorder script and make sure the GC traces it.
	3f653ed082c6919e7fd127b12f2e510a9db68ce2	Andreas Gal — Remove InitTacer. Pointless for JSRuntime.
	8b55e6657beace519053785a5598a3723e50c214	Andreas Gal — Compiler fixes for CAS patch.
	acac4e2f37133db3f91904aac9c2aa5eb5d59317	Andreas Gal — Merge.
	3212c3f806cce803a5614c0542046159f914e657	Brendan Eich — Fix so it compiles, also avoid else after return.

	16ffabb5defbb8c5480573e57764c580bef26876	Andreas Gal — Move all inlines that do not represent primitives out of jsinterpinlines.h since we don't have to overwrite them in jstracerinlines.h. They live in jsinterp.cpp now. Added missing error handling for prim_ddiv and prim_dmod. Make sure prim_ddiv and prim_dmod do not call other primitives. Fixed bug in dmod (-1 should be n, but since all invocations had n=-1 this was a non-issue).
	cc2af8bca37f0d5641f8099423574fcfe831c567	Brendan Eich — Fiddle loop table slot interface and impl in hope of freeing slots over time.
	224cd9c69a164a5b040cdec99f794a2b50ddfae2	Brendan Eich — Use correct idempotent include guard macro name.
	b8bab0f8f4a135802b3d614398b7aa973dce4412	Brendan Eich — Merge and undo js_AllocateLoopTableSlot reparam.
	69e89ed25d335659980fe1ec708dddeb1dc715e8	Brendan Eich — No JS_TRACER ifdefs, keep line len < 80, reparameterize jstracer.cpp functions, js_OpLength helper.
	6b03a869bb1cea802988c7eac042c67a82122ee7	Brendan Eich — Avoid overlong lines per modeline comments.
	5c416b3706ae7db79a9bc27563cf03d383c32790	Brendan Eich — Merge, style nits, no locking for tracing.
	2a51b11c390c0d826cffaa21fbb48ce559fc93c2	Brendan Eich — Left brace style.
	340fd2ddb2ae206533d473def16f7bfa28a22222	Brendan Eich — merge
	da54ae4ebb7c3adcf89174796f39ee3494cc9f8b	Brendan Eich — merge
	09d8fde18a45248202b1a122563f09312229ac01	Brendan Eich — Fix goof in switching from word to jsval counters.
	07a3235bb1f19842e1a051e155424cc44711a897	Brendan Eich — Instrument loop headers with jsvals above fp->vars and below fp->spbase.
	e707f1da531eb7d985fb0f26fe3b288113bb97fe	Brendan Eich — Split trace-supporting inlines, add ifdefs/macros for deriving js_TracingInterpret in jstracer.cpp.
	0ac401c7dcceefd8025ceaef027072f565a530c3	Brendan Eich — Style (and substance for vim users: left brace opening in column 1 enables [[ navigation).
	b46fcf1b955182486e98993738b5c9f1cf338099	Andreas Gal — Assign fresh loop table slots for all JSOP_HEADER opcodes in a script as it is thawed since the slots we stored there are likely stale by now.
	1805b63c9f77b324f91468614f00ee6b9e4a4d71	Andreas Gal — Fixed a bug that triggered the tracer at TRACE_THRESHOLD/2 already.
	5e055a8c1fef2ef1038820bc2285eca4b53e14dd	Andreas Gal — The table is now per-thread in a multi-threaded environment, and per-runtime otherwise. During code generation we merely allocate a loop table slot to each loop. Each thread will enlarge the table as needed in JSOP_HEADER.
	0c74d1995a37ea4f9844bb86023994fffff6fb00	Andreas Gal — Add a per-runtime loop attribute table that associates a jsval attribute with every loop in the code. The jsval is used initially as a counter until a certain threshold is reached, at which point the loop is traced and compiled and the resulting native code object is stored in the jsval to be executed for future encounters of the loop.
	5eee494d5f061157f47c00d9c76605c00fb7b7d5	Andreas Gal — Steer macro naming in jsinterinlines.h using a macro. This allows us to prefix all primitives with some prefix (i.e. interp_) when we compile the tracer and replace them with new primitives that invoke the interpreter version first, and then do some tracer specific action.
	bd1d2405ea5ecf6592cbeb4ff9b5682b7cc5cdec	Brendan Eich — Fix goof in switching from word to jsval counters.
	8019f065443a8ada678b2f8f1efcd8f5ed2c3350	Brendan Eich — Instrument loop headers with jsvals above fp->vars and below fp->spbase.
	4036ebe64345becdac54ca4c084f01a8cb5f4f85	Brendan Eich — Split trace-supporting inlines, add ifdefs/macros for deriving js_TracingInterpret in jstracer.cpp.
	c75cf4011be75d3db32d4db7ed7096cc21f91f80	Brendan Eich — Style (and substance for vim users: left brace opening in column 1 enables [[ navigation).
	1c495025f185a9e1e3beb14f064b88af12e20e68	Andreas Gal — Make relational operations (<,<=,>,>=) traceable.
	cca08ddd5e978ee3e055b576b522f884a57720e2	Andreas Gal — Mark getting and setting arguments and local variables as safe for tracing.

	bc4ea1dfdb2db4f84f18cd9e712b541cb0c0f7ac	Andreas Gal — Enable tracing for selected opcodes that do not have any remaining tracing hazards.
	1e8aed6c7201d4db8e8ff1eb332ad8654888d10d	Andreas Gal — Opcodes that can be traced through can be declared with TRACE_CASE(op). Currently all opcodes are declared as BEGIN_CASE(op), which automatically aborts trace recording. In addition, error handlers (defined with DEFINE_HANDLER) also abort trace recording. At every backwards branch trigger monitor_branch(), which will monitor for new trace tree anchors.
	5c552143c1b3c335cd55bdc38d2368213815777b	Andreas Gal — Introduce primitives for common binary operations.
	343a7e6713a3673d1884d728b97b82a8412e69b9	*Andreas Gal — Convert macro code in jsinterp.cpp into inline functions and introduce trace primitives (prim_, guard_, call_).**
	5c9fdaab8776db17eab4258784a15f3fca4e675c	Brendan Eich — From Igor's patch for bug 433382.
	251c171475d361646abfddf5df87e29505b6c95a	Brendan Eich — Fix bad merge.
	5783ce0bad4f085912b1697ccfed22b61e150798	Brendan Eich — Igor's patch for bug 433382, r=me.
	9f158c90185bcae0c60c7376b9039095c3202bca	Brendan Eich — Fix POP_STACK to take a macro out param.
	ef81950a59e686a777e38f128901b352befcd381	Brendan Eich — First round of macro cleanups to enable tracing.
