As for why stuff doesn't work, have you guys tried reverting my last changes to
sysdepCallMethod and the ppc trampoline? I probably screwed it up wrt darwin
when I was getting linux to work.
Hi Tim!
In order to get familiar with the jit3/ppc setup i thought about porting the mnemonicizer setup to x86. Does that souind like a useful idea?
The script is a bit specific to PowerPC/RISC architectures, and x86 is so different
at the bit level that I don't think it'll help much.
ah! xdebugging works with ppc?
It should, whether or not it works has more to do with the toolchain than the CPU.
# disassemble the native code.
(gdb) disas meth.ncode # or whatever the structure is nowadays
It doesn't always work quite right unfortunately, but it should get you pretty far.
thanks :) any ppc-assmebler reference you could recommend?
I was using the "compiler writers guide" and the main architecture manual that I
got in pdf form. Unfortunately, I don't have the links handy. For dealing with
ABI stuff, the OS-X stuff should be in the "mach-o" runtime documentation
provided by apple, i think.
cheers, dalibor topic
