578c29bb08 Sort interned global slots in ascending order for fast comparison of two different global frames when switching between them. 2008-07-28 16:49:13 -07:00

cc8e0edecd Trash the interned globals of a tree if we experience a global shape mismatch. 2008-07-27 21:44:08 -07:00

3dd8ac9ceb Trash the typemap if a change of the global shape forces us to throw away a tree. 2008-07-27 19:18:51 -07:00

824ec3d48f Track the type of guards and react accordingly if we bail out on them. Guards that protect against out-of-memory conditions don't try to grow the tree. Instead we just resume the interpreter. 2008-07-27 16:18:53 -07:00

141edf8a24 do setelem in a builtin, so we don't abort trace every 8 times when growing 2008-07-27 18:34:23 -04:00

f9440fa493 If we see a f2i(UnboxDouble) chain, simplify it to UnboxInt32 which does the conversion internally. This also enables a fastpath to read 31-bit jsval integers from arrays. 2008-07-27 14:55:26 -07:00

5234290eaf Smarter speculative demotion of numbers to integers and promotion of the trace seems to require actual doubles. If the number at entry looks like an int we make the slot an int and compile as such. If the loop-tail proves the slot to be a double, we recompile the trace. Currently such miss-speculation cannot be handled on secondary traces since we are currently unable to recompile the primary trace. Such secondary traces are blacklisted. 2008-07-27 02:15:17 -07:00

aec2839ca9 Don't try to demote slots on secondary traces (we have to recompile the primary trace as well for that, which we currently don't do.) 2008-07-25 19:30:33 -07:00

67298590aa Eliminate EntryRegs. Its not safe to keep a reference to the entry SP since we might extend the tree from a different outer stack frame. Instead just store the entryStackDepth. 2008-07-25 18:22:15 -07:00
Andreas Gal
164b2b6bb5 Print real recording point, not entryRegs and add an assert that makes sure the guard we come out of is associated with the tree we entered into. 2008-07-25 18:13:57 -07:00

5e2eaa71ff The VP engineering broke JSOP_NAME! We have to check whether the slot is actually interned and otherwise abort. 2008-07-25 16:51:42 -07:00

3a43211d7f Can't use lr->from. Seems to not get set in certain cases. Go figure. The nanojit tree code is really weird. 2008-07-25 02:29:36 -07:00

8278ce69a1 Make the interpreter notify us when frames are popped so we see he right cx->fp value. Fix return value tracking for JSOP_STOP. 2008-07-24 10:35:10 -07:00
Andreas Gal
9780602644 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

0a1e83ca07 Maintain a separate frame for globals using InterpState->gp. 
This will allow nested loops to access the globals interned by outer loops while at the same time sharing parts of the stack of the outer loop.

d66db351a0 Add a fast path for nativeFrameOffset that walks entire groups at a time, not slots. Check against the result calculated by the FORALL macro in DEBUG builds (for sanity). 2008-07-23 16:39:17 -07:00

0c67428824 Merge. Make sure we clear out all slots from the tracker when leaving a frame. 2008-07-23 15:56:27 -07:00

475f3b2370 When addressing locations above the stack water level, use ->sp as base. Shaver accidently changed this to ->spbase when merging Igor's patch, so we were writing past the water mark and the stores were killed. 2008-07-23 15:48:15 -07:00

e0f05951e4 Lazy fill the stackTracker as we lookup the nativeFrameOffset for values. Purge all entries related to the current frame when it is popped. This code could be further simplified if Tracker was a template. 2008-07-23 02:57:56 -07:00
