600b9c3e14 Remove type-map hash code. A direct memcmp seems to be faster (probably some SSE magic behind it in gcc/glibc). 2008-08-07 16:26:56 -07:00
Andreas Gal
27e8ef817a Factor out the code to capture the current stack type map and move around the type map method implementations to make sure they can see the FORALL macros. 2008-08-07 16:23:50 -07:00

01e3af1f79 We expect no interned globals in a new tree. Assert on that. 2008-08-07 15:44:11 -07:00
Andreas Gal
00b12bbaca Always trash TreeInfo when we recompile. This avoids the much dreaded JS_ASSERT(insInt32) errors and we can do this now because the demotion information is provided by the oracle and no longer stored in the typemap directly. 2008-08-07 15:38:54 -07:00
Andreas Gal
95f5262e4f Use an oracle to predict when slots are demotable. This allows trashing the TreeInfo* object in the root fragment more aggressively. Rebuild the stack type map at every compile to avert type map mismatches. Purge all global slot info when we re-record a tree. 2008-08-07 15:28:43 -07:00

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
Andreas Gal
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
Brendan Eich
6e215765df - Add builtins to support for-in loops, both iterating and getting/setter properties by name using o[i] instead of o.p where i is 'p'. 
- Record JSOP_ITER and JSOP_ENDITER, which must be handled since tracing could start in between them (and always will, until we nest or unless we outerline).
- Add a null state guard in JSOP_FORVAR's recorder method.
- Pick include order, indentation, and trailing space nits.

03b511f9e4 - Use JSStackFrame* fp over, don't declare another JSStackFrame* f, in the FORALL macros and clones (f is canonical variable name for nanojit::Fragment*, fp for JSStackFrame*). 
- Nit-pick include order (alphabetical within each group).

Brendan Eich
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).

fe3a6127c5 - Export JSSLOT_ITER_* from jsiter.cpp to jsiter.h, for jstracer.cpp to use. 
- Fix OBJ_GET_SLOT to be STOBJ_GET_SLOT in jsiter.cpp, no thread safety here (bug on file).
- Move JSNativeEnumerator from jsobj.cpp to jsobj.h for jstracer.cpp as well.
- Rename JOF_2BYTE JOF_UINT8 for consistency, and actually decompile it.
- Trace JSOP_FORVAR (can't do anything in JSOP_ITER, it comes before the loop).
- Shortened some guardMyLongSummerVacationWithinBounds names ;-).
- Removed/refactored to avoid dslots_ins obligation on all callers.

f1a5494d05 Major shakeup of the interning code for globals. Globals are now detected on demand as they are used and the slots are noted in treeInfo->globalSlots. At the same time the type is recorded in treeInfo->globalTypeMap. The stack type-map is maintained separately in treeInfo->stackTypeMap. All these structures are lists and are maintained as List<T> objects. Imports for globals can appear at the top (if we have already seen some imports for the loop header and are recompiling), or on the fly for lazily found values. We no longer intern all global properties that happen to match a name in the current function, and we also support inlining of functions that touch globals that are not used in the method where the trace started in. 2008-07-30 04:17:22 -07:00

5ae4ef819e Backed out changeset a58e7ce6eb7f. stack(0) is wrong, if at all it should have been stack(-(1 + argc)). But anyway, its impossible to write through to the frame via set() at that point because leaveFrame() doesn't actually modify cx->fp. We need to wait for the interpreter to do so. Until then nativeFrameOffset produces incorrect values and the assert fails in set. 2008-07-24 10:09:51 -07:00

b5e654f120 5 hours of debugging, and 9 keystrokes to fix it. That was one expensive bug. shaver's reduced fannkuch example works now. I think independently of this one we don't check properly for index underflow in dense arrays. Shaver is going to have to take a look at that (this fix makes fannkuch indexes not become negative, but doesn't explain why we crash so hard if they do become negative). 2008-07-12 00:27:21 -07:00

b222836a73 Don't demote u2f conversions and sink the type cast into the side exit type map, because this loses the sign bit for unsigned values. We could fix this by adding an explicit unsigned type to the map, but for now I think we should stick to int/double only since there is the risk of fanning out trees. Crypto doesn't seem to use ush all that much so we should be ok performance-wise. 2008-07-11 13:18:29 -07:00
