Re: [Libjit] Endless loop on jit_function_compile

[Mario Morgenthum]

Hi Aleksey,

it seems that libjit doesn't support the microsoft x64 calling convention (see jit_builtin_apply in jit-apply-x86-64.h ... this is system v x64 -> https://en.wikipedia.org/wiki/X86_calling_conventions#System_V_AMD64_ABI). Cygwin uses the native windows calling convention (see https://cygwin.com/cygwin-ug-net/programming.html#gcc-64). I think thats the problem.

Now I built it with --host=i686-w64-mingw32 (and i686-pc-cygwin). Dumping a function with jit_dump_function works, but every time I want to compile it with jit_function_compile, the application ends in an endless loop ... even with an empty function. The same application works with os x. Are there any known issues/solutions for this problem?

IIIRC I never tried it with cygwin64, if you will be able to come up with a patch, I’d happily apply it. I might try to solve the problem too but it will take some time unfortunately.
