* RETF modifies BASE. Treat it like a store or it gets CSEd.Mike Pall2010-02-042-1/+3
|
* Reset the hotcount table after a JIT off to on transition.Mike Pall2010-02-043-15/+18
|
* Add shadow frame link stack for trace recorder.Mike Pall2010-02-046-56/+82
| | | | | Simplifies snapshots. Prerequisite for pre-call snapshots. Increases consistency for fast function calls, too.
* Fix unroll limit checks and frame depth adjustment for pcall.Mike Pall2010-02-031-13/+11
|
* Clean up frame depth checks and loop detection.Mike Pall2010-02-033-6/+12
|
* Add extra check to suppress hotcall event during recording.Mike Pall2010-02-031-2/+3
|
* Another loop formation test must check for return to lower frame.Mike Pall2010-02-031-1/+1
|
* Improve coalescing of BASE register in side traces.Mike Pall2010-02-011-21/+47
|
* Revise hardcoded inlining in lj_asm.c. Saves 1-2K.Mike Pall2010-01-301-4/+4
|
* Add support for weak IR references to register allocator.Mike Pall2010-01-301-18/+51
| | | | | | Spilling a weak ref forces a spill slot, but omits the restore. Spill slots for snapshot refs override the register, anyway. Marking snapshot refs weak avoids pointless restores.
* Loop formation test must check for return to lower frame.Mike Pall2010-01-291-1/+2
|
* Compile return to lower frame. Only for Lua frames right now.Mike Pall2010-01-293-40/+75
|
* Followup fix: set maxslot for continuation return.Mike Pall2010-01-281-0/+1
|
* Drop obsolete frame shrinking after continuation return.Mike Pall2010-01-281-4/+1
|
* Fix recording of metamethod result adjustment.Mike Pall2010-01-281-1/+1
|
* Don't modify jit_State and exit counters while in vmevent.Mike Pall2010-01-281-15/+16
| | | | Fixes crash with hot loop in TEXIT callback which cleared J->parent.
* Avoid reuse of PHI registers, even for duplicate right PHIs.Mike Pall2010-01-271-1/+1
|
* Expose compressed snapshot map to reflection API.Mike Pall2010-01-271-16/+5
| | | | Update jit.dump module and restore printing of frame separators.
* Eliminate IR_FRAME. Replace with KGC and TRef/SnapEntry flags.Mike Pall2010-01-274-105/+81
|
* Add frame and continuation flags to TRef and SnapEntry.Mike Pall2010-01-275-39/+57
|
* Add missing check for return to lower frame.Mike Pall2010-01-271-1/+2
|
* Cleanup types for narrowing stack machine.Mike Pall2010-01-271-28/+35
|
* Compress snapshots using a simple, extensible 1D-compression.Mike Pall2010-01-2611-319/+365
| | | | | | Typically reduces storage overhead for snapshot maps by 60%. The extensible format is a prerequisite for the next redesign steps: Eliminate IR_FRAME and implement return-to-lower-frame.
* Add missing eviction in asm_obar().Mike Pall2010-01-261-0/+1
|
* Fill gaps in frames (caused by metamethod calls) with nil.Mike Pall2010-01-263-5/+5
| | | | Simplifies storing snapshots to stack.
* Use dedicated type for snapshot map entry.Mike Pall2010-01-258-33/+36
| | | | Preparatory work for compressed snapshots.
* Force error if lua_newstate() is used in 64 bit mode.Mike Pall2010-01-243-0/+21
|
* Integrate MinGW build with DWARF2 exception handling.Mike Pall2010-01-227-31/+216
| | | | | | | | Only works with DWARF2-enabled GCC 4.x (not the default MinGW GCC). Fix fastcall symbol names for COFF assembler output. Add DWARF2 unwind info to COFF assembler output. Use COFF assembler mode for MinGW builds. Always enable the DWARF2 handler if compiled with GCC.
* Fix undefined behavior in table resizing calculation.Mike Pall2010-01-211-1/+2
|
* Fix ordered string comparisons. Unsigned arithmetic is evil.Mike Pall2010-01-211-1/+1
|
* Decouple guard vs. INT check vs. TYPECHECK semantics for SLOAD.Mike Pall2010-01-193-7/+14
|
* Fix broken intarith + testop optimization.Mike Pall2010-01-191-1/+1
|
* Add some sanity checks for allocator in 64 bit mode.Mike Pall2010-01-184-1/+8
|
* Reduce non-numeric tag range by bumping up 64 bit lightud tag.Mike Pall2010-01-181-6/+6
|
* Fix more 64 bit conversion warnings.Mike Pall2010-01-171-2/+2
|
* Silence 64 bit conversion warning.Mike Pall2010-01-171-1/+1
|
* Enable build for x64 interpreter on WIN64.Mike Pall2010-01-171-2/+11
| | | | | | To build the x64 interpreter open a "Windows SDK Command Shell". Then set the compiler environment: setenv /release /x64 Then cd to the src directory and run msvcbuild.bat.
* Allocate 32 bit memory on WIN64 using NtAllocateVirtualMemory.Mike Pall2010-01-171-7/+48
|
* Fix off-by-one error in x64 PE object symbol mangling.Mike Pall2010-01-171-1/+1
|
* Error for blacklisted loop bytecodes has no info argument.Mike Pall2010-01-161-1/+1
|
* Add build infrastructure for x64 interpreter.Mike Pall2010-01-144-6/+4655
| | | | | Must be explicitly enabled with: make clean && make "CC=gcc -m64" Only works on Linux/x64. Does not work on WIN64 or OSX/x64 (yet).
* Shorten %p format for pure 32 bit pointers on x64.Mike Pall2010-01-141-3/+7
|
* Strip '@' suffix from external symbols for MACH-O, too.Mike Pall2010-01-101-17/+16
| | | | Fixes OSX build.
* Improve alias analysis of upvalues using a disambiguation hash value.Mike Pall2010-01-096-13/+30
| | | | | | | | All upvalue objects hold a disambiguation hash value now. It's built from the parent prototype and the slot number. Different hash values imply the upvalues cannot alias. Same hash values don't imply anything (collision or different closures). Upvalue disambiguation makes use of a reduced hash due to IR contraints.
* Avoid int16_t widening for pt->uv elements.Mike Pall2010-01-094-8/+13
|
* Fix 32/64 bit portability issue with upval->v.Mike Pall2010-01-097-22/+21
|
* Fix x64 PE object emitter.Mike Pall2010-01-091-1/+1
|
* Bump all copyright dates to 2010.Mike Pall2010-01-0985-86/+86
|
* Add support for WIN64 exception handling to external unwinder.Mike Pall2010-01-055-44/+177
| | | | | | Modify unwinding to always return _ff or _c unwind type. Generate PE object .pdata/.xdata sections for x64 interpreter. Can drop r12-r15 saves in Windows/x64 interpreter now.
* Fix PE object build for fastcall entry points into interpreter.Mike Pall2010-01-054-6/+20
