Bug 97954: Allow SpiderMonkey to be built on its own, or as part of Mozilla. Give SpiderMonkey its own configure script and top-level Makefile. Adjust js/src/Makefile as appropriate for life as a stand-alone makefile, instead of a 'make export; make libs'-style Mozilla tier makefile. Have the configure script accept '--with-nspr-cflags' and '--with-nspr-libs' options for using an in-tree NSPR. Also accept '--with-system-nspr', '--with-nspr-prefix', and '--with-nspr-exec-prefix' flags for using an installed NSPR. Default to --disable-jemalloc, assuming we don't have that part of the tree available; have the top-level configure script pass --enable-jemalloc as needed. Since we no longer have an export phase to copy header files into dist/include/js before we build the library, we need to be able to find nanojit.h in the nanojit directory; fix references in jsbuiltins.h and jstracer.cpp. Give SpiderMonkey it its own copies of many of the files from ./config and ./build. These are all exact copies, except as follows: . js/src/config/Makefile.in: js/src only has a subset of js/src/config, and thus a subset of the makefile targets. . js/src/config/autoconf.mk.in: js/src/configure.in has its own make variables to set, not set by the top-level configure script, so it needs a custom automake.mk template. . js/src/config/make-system-wrappers.pl: a copy from nsprpub/config, so that we can build without having an NSPR source tree handy. Invoke js/src/configure from ./configure, passing the values computed for NSPR_CFLAGS and NSPR_LIBS by the top-level configure script. Treat js/src as a static directory of the js tier, and create a new config/js (just a Makefile) to be the js tier's non-static directory. Let js/src/configure generate SpiderMonkey's makefiles, not ./configure. Generate a 'js-config' script, which clients can call to find the CFLAGS and LIBS values necessary to compile and link against an installed SpiderMonkey library. Don't include the js-config script in Macintosh packages. Teach client.mk how to rebuild js/src/configure. Tell Mercurial to ignore files generated by autoconf in js/src. Further work: . Right now, callers must define JS_THREADSAFE when #including jsapi.h. This is fixed in a subsequent patch. . js/src/configure is a trimmed copy of ./configure. It could be trimmed more.
