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.

d8e1964581 Fix for build breakage on Windows due to bad dom_quickstubs.depends file. 
The bad file contains a backslash, which causes GNU make to choke.
This fix causes the file to be generated correctly, but the file on
the Windows build machines is still there and still contains backslashes;
a clobber should fix this.

The Try Server didn't catch this because every Try build is a clobber.

c86c7d09fb Generate an always taken LOOP_EXIT guard when an inner loop encounters a break statement. When returning from such an inner tree, make sure the recorder resumes at the target address of the goto the break was emitted as, otherwise the outer tree confuses the location with a break in its own loop. Disabled outerlining (this patch subsumes it, but we might enable it later since it might handle some cases more efficiently, currently off for debugging through). fasta currently asserts, and fannkuch hits a perf regression. These are probably bugs this change exposed. 2008-08-25 17:24:49 -07:00

87a6e416ef 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). 
2. Use if (C) { do {...} while (C); } instead of if (C) { while (C) {...} } and other style fixage.

Andreas Gal
2d983bcee2 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. 2008-08-17 00:30:36 -07:00
Andreas Gal
ef8a6041cc 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.

26fc76213a 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.)

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. 2008-08-12 20:18:29 -07:00

2991c66416 - 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. 
- 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).
- Cope with C clients of jscntxt.h and its include files (these hacks should go away).
- Naming convention and function definition line-break style nit-picks.

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. 2008-08-08 18:52:08 -07:00
