llvm dev - Aug 2005 - [LLVMdev] X86ISelPattern.cpp:73: undefined reference to `X86CompilationCallback

Hi LLVM'ers,

I can't figure out why I get this error:

--------------------------------------------------

If we look at the contents at line 73 in file X86ISelPattern.cpp there 
aren't any references to functions X86CompilationCallback*.

Any ideas?

Take a look at X86JITInfo.cpp and search for that missing symbol.
You have to either add recognition for MinGW for the preprocessor or
add a MinGW-specific asm implementation of that function.
