Here is a full patch including Nathan's COFF support, tests that pass on Windows, and some changes to lit. Obviously the COFF support and changes to lit should be separate patches in the end. http://codereview.appspot.com/1624043/show - Michael Spencer -------------- next part -------------- A non-text attachment was scrubbed...

Hi guys, I have attached my patch to support generating win32 COFF object files. I would have posted earlier, but my system drive crashed and I had to rebuild my system; Luckily, my source code was on a secondary drive. I think this would be a good beginning for ongoing support of the COFF object file format and was hoping for some feedback as to whether it was commit worthy or what was needed to

I'm so close to having LLVM build on PowerPC. If there's any PowerPC experts, help? Lines like this: outs() << "[" << format("%2d", i) << "]" << "(sec " << format("%2d", int16_t(symbol->SectionNumber)) << ")" << "(fl 0x" <<

Hi, I finally got my first .obj file patched with .debug$H to look somewhat right. I added the new section at the end of the file so I don't have to recalculate all sections (although now I probably could position it in the middle, knowing that each section is: SizeOfRawData + (last.Header.NumberOfRelocations * (4+4+2)) and the $H needs to come right after $T in the file). That although illegal based on the coff specs doesn't seem its going to influence lld. Also we talked and we are probably going to do something similar to a bunch of windows defines and a check for our own define (to guaran...
