9a682f341d Revise hardcoded inlining in lj_asm.c. Saves 1-2K. 2010-01-30 14:33:08 +01:00

02e58f5e56 Add support for weak IR references to register allocator.
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.

67ca399a30 Compress snapshots using a simple, extensible 1D-compression.
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.

43f1e13470 Integrate MinGW build with DWARF2 exception handling.
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.

09ca54d9bc Enable build for x64 interpreter on WIN64.
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.

99d153bef9 Improve alias analysis of upvalues using a disambiguation hash value.
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.
