Mike Pall 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.

Mike Pall 43f1e13470 Integrate MinGW build with DWARF2 exception handling. 
Only works with DWARF2-enabled GCC 4.x (not the default MinGW GCC).

Add DWARF2 unwind info to COFF assembler output.
Use COFF assembler mode for MinGW builds.
Always enable the DWARF2 handler if compiled with GCC.

Mike Pall 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.

Mike Pall 49e3bdf080 Allocate 32 bit memory on WIN64 using NtAllocateVirtualMemory. 2010-01-17 20:20:43 +01:00

Mike Pall 82417ee889 Add build infrastructure for x64 interpreter.

Mike Pall 767035f031 Strip '@' suffix from external symbols for MACH-O, too. 
Fixes OSX build.
 2010-01-10 09:39:05 +01:00
Mike Pall 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.

Modify unwinding to always return _ff or _c unwind type.
Generate PE object .pdata/.xdata sections for x64 interpreter.

Mike Pall 93ee10642e Major rewrite of error handling to allow external/internal unwinding. 
Make external unwinding the default on x64.
It's mandatory on WIN64 due to the abundance of callee-saved regs.
Allow piecewise internal frame unwinding and optional cleanup.
Store ERRMEM, ERRERR and ERRCPP early and copy down later.
Use FRAME_CP for lj_vm_resume.
Add lj_vm_unwind_*_eh variants as landing pads for external unwinder.
Use fastcall for lj_vm_unwind_*.
Can drop r12/r13 saves in POSIX/x64 interpreter now.

Mike Pall d18d1573d8 Save all callee-saved x64 integer regs for unwinding.
