Re: [Dotgnu-libjit] 64bit integers operations on x86

[Kirill Kononenko]

Try insert jit_dump_function(stdout, function, 0); before
jit_function_compile and after. This should print intermediate form
and assembly code. Please send to this maillist the dump/pastbin in
case it crashes.


Thanks,
Kirill
