90bf6a2d1e Bug 97954: Give jsconfig.h a better name, and make room for the new js-config.h. r=bsmedberg 
We'd like the SpiderMonkey configure script to generate a header file
named js-config.h to hold #definitions chosen at configure time that
affect the SpiderMonkey API, like JS_THREADSAFE.  However, that name
is very similar to that of an existing header file, jsconfig.h.  This
patch renames the existing header file, and updates all references to
it.

--HG--
rename : js/src/jsconfig.h => js/src/jsversion.h

1d525db0e4 New attempt at fixing 453235. If building without JIT (like PPC/MacOSX), don't include the deep abort calls in jsinterp.cpp 2008-09-01 18:40:45 -07:00
Andreas Gal
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
Andreas Gal
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

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.

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).

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.

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

de3107d2ee Add a per-runtime loop attribute table that associates a jsval attribute with every loop in the code.

33ec9a35fb Opcodes that can be traced through can be declared with TRACE_CASE(op). Currently all opcodes are declared as BEGIN_CASE(op), which automatically aborts trace recording.
