[LLVMdev] Bad Instruction 4 with fastcc

[Timothy Baldridge]

On OSX I thought I'd try to optimize my compiler a bit by switching some of
the calling conventions from CCallingConv to FastCC. The compiler ran fine,
but when I executed the code, I got "Bad Instruction 4". I'm seeing some
other mentions on this mailing list of issues like this on OSX (I'm using
10.8). Is there anything I need to change to enable fastcc with my
compiler? I also tried the X86FastCCCallingConv and that died with the same
error.

Thanks,

Timothy
