Bug 1494894 - sidebar CSS: use color instead of opacity for unselectable items;r=ladybenko Depends on D9652 This allows the Connect button to no longer look disabled. However we could maybe mutualize colors a bit more, either with a --color-disabled variable or with a class. Differential Revision: https://phabricator.services.mozilla.com/D9653

Bug 1502051 - BaselineCompiler should use JSScript::yieldAndAwaitOffsets. r=jandem It currently generates the same table in a round-about way so we should just use the same table for consistency. Note that the BaselineScript still gets it's own yield/await offsets table that is tracked in native address offsets. Differential Revision: https://phabricator.services.mozilla.com/D9800

Bug 1502051 - Cleanup BaselineScript::nativeCodeForPc. r=djvj Add a maybeNativeCodeForPc that returns nullptr on optimized-out code. This is useful later for generating mappings without having to first determine 'dead code'. Also reorganize the logic a little. Differential Revision: https://phabricator.services.mozilla.com/D9799

Bug 1502051 - Always check slotInfo for BaselineScript::nativeCodeForPc. r=djvj Make the slotInfo argument required and assert that stack is synchronized. A native code address for baseline is only well-defined if the registers are setup correctly. Existing code was fine, this just asserts some previously un-documented things.

Bug 1502051 - Cleanup BaselineScript entry point names. r=jandem These are very specialized entry points so instead name them after their use cases to make code easier to read and keep in sync. Differential Revision: https://phabricator.services.mozilla.com/D9789

Bug 1502051 - Cleanup up BaselineScript initializers. r=djvj - Use C++ member initialization to simplify constructors. - Mark class as final since it has trailing allocations. - Make constructor private. Differential Revision: https://phabricator.services.mozilla.com/D9787

Bug 1460914 - [xpcshell] Define preferences in testing/profiles instead of testing/xpcshell/head.js, r=ted This commit creates an empty 'base' profile because I wanted to preserve the ability to apply a pref to all test harnesses on try. Since xpcshell doesn't share many prefs with the other harnesses, it can't use the common profile. So adding a pref to 'common' will apply it everywhere except xpcshell. Adding a pref to 'base' will apply it everywhere including xpcshell. These profiles are starting to get a bit messy, but I'd like to punt re-organizing them to a follow-up bug.

Bug 1460914 - [xpcshell] Use nsIPrefService.readUserPrefsFromFile to set prefs, r=ted This uses nsIPrefService.readUserPrefsFromFile to set preferences from a user.js passed in via the python harness. This allows us to use the profiles under testing/profiles like all the other harnesses and will make setting prefs in xpcshell easier to use and understand.
