6bc330ef33 Don't disable property caching in eval (this requires GC'ing eval scripts). Do tolerate active Call object at head of scope chain in record_JSOP_CALLNAME, and go straight to the stack slots. 2008-08-20 14:04:37 -07:00

0d83651633 - Skip dense array object, try prototype, in all JSOP_GET*PROP variants, interpreter and tracer. 
- Test entry instead of retesting aobj->map->ops->getProperty == js_GetProperty in JSOP_CALLPROP.
- Handle object and null types as well as booleans in record_JSOP_NOT.
- Trivially implement JSOP_STRICT{EQ,NE} recording by forwarding to the non-strict record methods. This works so long as the latter trace only same-type operands and do no conversions.

64fc3b0367 - Fix shapeless callee guarding to guard on function object value. 
- Add JSOP_NULLTHIS to help the tracer guard shapeless callees (see trace-tests.js)
- Culled bogus record_JSOP_CALLGVAR left-over forwarding to record_JSOP_GETGVAR.
- Better shapeless callee tests.

8f837e0784 - Implement interpreter frame reconstruction (js_SynthesizeFrame). 
- Fix MONITOR_BRANCH to restore frame-dependent interpreter locals (we want fewer of these if they can be removed with no perf loss).
- Fix FORALL_SLOTS_IN_PENDING_FRAMES not to scan argv in callee when it has scanned operand stack in caller.
- Fix import to take the localFrame from whose fun its localNames parameter was computed -- it was using cx->fp which is wrong when FORALL_SLOTS_IN_PENDING_FRAMES iterates other than the top of stack frame.
- A few interval tests that were double-ended are single-ended now.
- Add call.js mini-test (more cases needed).

a17263a036 1. Fix !JS_THREADED_INTERP bugs in BRANCH and recording switch case generation. 
2. Rename TraceRecorder op methods to record_JSOP_xxx to avoid shadowing JSOP_*
   enumerators used inside jsopcode.h macros -- death to ::JSOP_*!
3. Added atoms TraceRecorder member for giant literal pool scripts.
4. Condition assert in TraceRecorder::test_property_cache_direct_slot to avoid
   false positive when executing function code accessing a global.

e70272bfab Removed attempt to imply ints into doubles on the fly. This can't work. Use proper float loads where needed and add some initial code for builtin functions. 2008-07-02 14:38:12 -07:00

0d7c8f648b Indicated in a separate primitive when integers get stored as a double because they don't into a jsval. 2008-07-02 09:38:55 -07:00
Andreas Gal
8113879262 This patch eliminates ValueToECMAInt32 and instead tries to emit specialized code depending on the true type. 32-bit integers are detected and treated like integers in fetch_int via ValueToECMA32. Similarly, int store_int NewIntInRootedValue is used if the value is really an underlying int. NewIntInRootedValue is a nop on the trace. 2008-07-02 03:33:18 -07:00

Andreas Gal
1567618f99 Better naming (MARK_EXIT => MARK_REGS). 2008-06-30 18:41:22 -07:00
Andreas Gal
84274f1b33 Save the VM registers into markRegs at opcode entry and restore that state when ending or aborting recording. The same info is pushed into sideexit and used by guards. With this change we can eliminate the hack in MONITOR_BRANCH that had to adjust the stack pointer depending on the opcode type, and it also allows us to trace through the recently added boolean guard opcode fusing. This improves trace code quality, since only the pre-conditional check state is saved. The guard restores into that state, so the trace code doesn't have to emit the value of the conditional evaluation onto the stack, saving a handful ops. 2008-06-30 18:31:29 -07:00
Andreas Gal
19b4bcdc69 Save the side exit state at entry in to the opcode (since we want to restart ops) and enable store filter. 2008-06-30 17:12:52 -07:00

b3060293c7 When a conditional branch instructions terminates the trace, we have to make sure its restartable, so put the conditional value it was deciding on back onto the stack by incrementing sp before jumping back to the outer interpreter. 2008-06-29 15:21:50 -07:00
Andreas Gal
253b2572b2 Initialize jump table when side-entering the interpreter. Keep track of cx and sp directly in the recorder instead of going through the tracker. 2008-06-29 13:53:40 -07:00
