similar to: [LLVMdev] Win32 COFF Support - Patch 3

This probably needs to be slightly tweaked to work with mainline. I don't see anything objectionable, but I think Daniel needs to review this one.

Attached is patch number 4. - Michael Spencer

I have updated my patch based on Chris'es feedback. I removed the dbgout_calls macro, but left others in place for now. If there are no objections, I would like to commit this tomorrow evening (~7PM GMT-7). I have compiled and tested it on MSVC, with Michaels testing code and it looks good. Once this is committed, Michaels patch can be applied. -Nathan -------------- next part --------------

Hi Nathan, I'm not quite ready to apply this patch, but I now have time again to work on getting it in. The main reason I am not willing to put it in yet is (a) the size, and (b) the inconsistences with LLVM style. Please fix the following things: - Watch out for case mismatches, i.e., #include "WinCoff.h" when the header is actually WinCOFF.h. - The patch doesn't have a

Nathan used write_uint32_le in WinCOFF.h, and I guess accidentally used it in WinCOFFObjectWriter.cpp.

Ah, I didn't notice that. Here's yet another style patch. Thanks to coppro for the review that found most of these. (note, I made a branch and did a rebase just so I

write_uint32_le is used to write into a arbitrary data buffer, where as WriteLE32 is used to write into the object file.

Right on, thanks for working on this. I have been busy lately, but its good to see progress being made.

Hi Michael, Overall patch looks good. I do have a few comments below. My main comment is please try to make the style match that used in the MCMachOStreamer more closely. I intend to refactor more functionality into the base MCObjectStreamer class, and having them use consistent idioms makes this easier; specific instances are included in the comments: -- > diff --git

I just finished the initial split up of WinCOFF.h into llvm/Support/COFF.h and lib/MC/WinCOFFObjectWriter.cpp. This includes almost the minimum changes required to split them up. WinCOFFObjectWriter now needs some refactoring to make things more consistent and less verbose. There also seem to be quite a few memory leaks that need to be resolved.

Hi Michael, Looks great to me, with the caveat that I know nothing about COFF. A few comments: - The term symbol is already very overloaded, I would avoid adding a new 'class Symbol'. - I find it annoying to have more versions of write little endian 32-bit data, but I'm not sure what the right solution is. We can clean this up later, perhaps. - There are a couple of instances of:

Hi guys, While trying to get dwarf debugging information to work with Win32 COFF targets, I came across a couple of issues with the current implementation of WinCOFFObjectWriter. Emitting empty section causes debug information to invalid, as the presence of certain debug section implies available information, and emission of labels as symbols confused gdb about the structure of the program. The
