|
* Enable tracing of recursion.Mike Pall2010-03-011-2/+1
| | | | | Now compiles tail-recursion, up-recursion and down-recursion. Benchmarks vs. Lua: fib 20x, ack 23x, binary-trees 4.7x.

|
* Rethrow errors from trace exit handling from the right C frame.Mike Pall2010-02-191-3/+11
|
* Use a different marker for hot calls.Mike Pall2010-02-151-3/+6
|
* Implement return hooks for Lua functions (zero-cost if disabled).Mike Pall2010-02-141-1/+7
|
* Implement call hooks (zero-cost if disabled).Mike Pall2010-02-141-12/+19
|
* Major redesign of function call handling.Mike Pall2010-02-131-588/+593
| | | | | | | | | | | Drop call gates. Use function headers, dispatched like bytecodes. Emit BC_FUNCF/BC_FUNCV bytecode at PC 0 for all Lua functions. C functions and ASM fast functions get extra bytecodes. Modify internal calling convention: new base in BASE (formerly in RA). Can now use better C function wrapper semantics (dynamic on/off). Prerequisite for call hooks with zero-overhead if disabled. Prerequisite for compiling recursive calls. Prerequisite for efficient 32/64 bit prototype guards.
* Move dispatch tables out of GG_State struct.Mike Pall2010-02-111-4/+4
|
* Switch to pre-initialized stacks. Drop frame clearing in interpreter.Mike Pall2010-02-111-28/+32
|
* Replace GCproto reference with bytecode PC in GCfuncL.Mike Pall2010-02-101-25/+26
|
* Drop bc field in GCproto since the bytecode is colocated.Mike Pall2010-02-081-3/+3
|
* Integrate MinGW build with DWARF2 exception handling.Mike Pall2010-01-221-0/+45
| | | | | | | | 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.
* Bump all copyright dates to 2010.Mike Pall2010-01-091-1/+1
|
* Add support for WIN64 exception handling to external unwinder.Mike Pall2010-01-051-17/+13
| | | | | | 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 Pall2010-01-051-2/+2
|
* Major rewrite of error handling to allow external/internal unwinding.Mike Pall2010-01-021-19/+11
| | | | | | | | | | | 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.
* Rename NRESULTS to MULTRES on the assembler side, too.Mike Pall2009-12-301-33/+33
|
* Implement yield from C hooks.Mike Pall2009-12-301-17/+12
| | | | | | Get number of multiple results from C frame. Add lj_cont_hook: restores multres and dispatch to static ins. Can use fastcall for lj_dispatch_ins() now.
* Minor fixes for x64 interpreter.Mike Pall2009-12-291-4/+12
|
* Add DWARF2 unwind info for x64 interpreter.Mike Pall2009-12-291-23/+65

|
* Save all callee-saved x64 integer regs for unwinding.Mike Pall2009-12-291-11/+19
| | | | | Temporary measure. Does not cover xmm saves on WIN64. May have to use unwind info or waste another 160 bytes per CFRAME.

* Add SSE variant of pow/powi to interpreter.Mike Pall2009-12-251-118/+300
| | | | | | Use SSE pow/powi helper functions from compiled code. Cleanup use of helper functions. Related cleanups of folding functions in x64 interpreter.
* Add build infrastructure for the SSE2-enabled interpreter.Mike Pall2009-12-221-1/+1
| | | | Works on x86 now. Will be enabled by default on x64 (not ready, yet).
