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.

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).

2d983bcee2 Try to execute the tree first, and if that fails worry about counting and triggering compilation.

- Use GCF_DONT_BLOCK from fastcall builtins that call into the GC allocator (mostly; a few places need help still, or better: need to avoid allocation).

9385e7842c 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. 2008-08-06 21:56:25 -07:00

2acb2afdec 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. 2008-08-06 13:41:04 -07:00

fcaab6d007 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. 2008-08-06 13:37:29 -07:00
