Same for me.

Wihtout the -march specified (using native x86 assembly) it does
convert it into assembly, but is uncompilable (with some unecognized "," (comma)
characters in the .s file).

Yes. X86AsmWriter should be fixed. I've submitted patches for that in
this maillist some days ago.

Does anyone have an idea why these two errors happen and has anyone
successfully used llvm-g++ on a WIN32 platform to compile files into bytecode
and used llc to convert back into C/assembly?

C++ is definitely broken on win32 platform due to many platform
specific issues (e.g. static ctors, etc.). Thank you for triggering
this bug - I'm working on this.

Hi Anton,
For the asm writer…i just cvs updated yesterday. Was something added in in the past 24 hours?

Could you resent? I cannot find your patch submission.

Thanks,

Hi Anton,
Is the patch going to be uploaded to the CVS source?

The patch is now in. Sorry about the delay!

Hi Evan,
I updated cvs and recompilled llvm. Still getting some unrecognized commas in the compilation of the assembly file after using llc. I guess this is still future work…

Hi Evan,
Actually the unrecognized commas disappeared with the patch. What remains is a call to “.local” which doesn’t exist in x86 or at least is not compilable by g++.

Hi Ashwin,

Thanks for testing it out. Free feel to contribute patches to fix the problems! :slight_smile: Given that I work for Apple, you can’t expect me to know anything about WIN32, right? :^)

It was my fault. It should be fixed soon.
