llvm dev - Jan 2010 - [LLVMdev] how to compile asm output for x86 with Micorsoft's ML

OK thanks, I'll look at that.

In the meantime, is it possible to get the assembly generated by llc
to work wiht ML? That would probably be the ideal solution.

Nope, llvm's .s output is only compatible with GAS and other at&t  
syntax assemblers.  It turns out that MASM syntax is highly ambiguous  
and MASM is not production quality for use by a compiler.  This is why  
visual studio doesn't go through it.  Long term, we'd like LLVM to be  
able to write out .o files directly, if you're interested in adding  
PECOFF support, that would be very nice :)

Crapola. I was afraid that was going to be the case. This was
originally something to do to have fun playing with Objective C, I'm
not sure PECOFF support would fall under that :)  Any idea how nasty
that would be?
Oh well, I guess the idea of doing this on windows isn't going to
happen anytime soon.
