4a36a6b709 Backed out changeset 25f856429db3. Wrong fix. Looks like jstracer.h is not included. We in fact can call methods of TraceRecorder directly. Sigh. I wish we had a try server. 2008-09-01 18:37:04 -07:00

fe70cfea9b Introduce js_DeepAbort to be used from jsinterp.cpp, instead of trying to call TraceRecorder->deepAbort directly (453235). 2008-09-01 18:32:41 -07:00

cda5a77a1b Fast followup fix for unintended change to 'f' prefix handling in TraceRecorder::record_JSOP_NEW (452878). 2008-09-01 01:44:26 -07:00
Brendan Eich
5a8cb06838 Kind of an Array initialiser tour-de-force for bug 452878:
1. Split FastNewArray from FastNewObject built-in for greater speed/specialization and further splitting into Array_1str, etc.
2. Add Array_1str, Array_2obj, and Array_3num builtins for benchmarked new Array(...) constructions.
3. Export ARRAY_SET_DENSE_LENGTH and ARRAY_GROWBY via jsarray.h to jstracer.cpp.
4. Tweaked SetArrayElement to make common/best case code be the predicted/prefetched path.
5. js_MakeArraySlow now preserves the pre-slow length in JSSLOT_ARRAY_COUTN as a jsval-tagged int if possible -- this will help the tracer avoid aborting on dense arrays that turned slow but not sparse by addition of a named property.
6. Export js_fun_apply and js_Object from their respective .cpp files, in these cases just to jstracer.cpp via local prototypes (no .h files involved).
7. More INS_CONSTPTR and INS_CONST macrology for better names in trace debug spew.
8. Fix TraceRecorder::test_property_cache to avoid aborting on JSOP_SETNAME that creates a new global, by setting it to undefined so it can be lazily imported. This helps 3d-raytrace.js, which has an unintended global loop control variable in a function.
9. JSTraceableNative loses its premature-deadwood tclasp member (my bad).
10. TraceRecorder::record_JSOP_NEW() handles 'new Object' now along with the 'new Array' variations. I also cut down the copy-paste code from JSOP_CALL's record method to mostly what is needed now.
11. Add KNOWN_NATIVE_DECL macro for concise prototype of library-private js_* native functions, and alphabetized the lists (too long for any other order to be winning).
12. Big honking special case for foo.apply(obj, [str]), which we can generalize as needed. Helps string-tagcloud.js. What's cool is how tracing allows us to rewrite this to foo(str) with this set to obj, eliminating the Function.prototype.apply. This requires some rewriting in JSOP_ENDINIT's record method.

1b5148d940 Bug 452905 - Make js_RecordTree printfs only appear with TRACEMONKEY=verbose. r=gal 2008-08-30 02:21:00 -07:00

c7604aac4c - Support JSOP_CONDSWITCH's JSOP_CASE and extended-jump-offset JSOP_CASEX variants properly.
- Fix sleep-deprived constant conditions due to failure to test flags & CMP_TRY_BRANCH_AFTER_COND!
- Use new TraceRecorder::fuseIf that Andreas added in a few more places where the previous try-branch-after-cond logic was open-coded.
