I'm looking at fixing some layering violations in LLVM & came across a few in the CodeView handling, specifically: lib/MC/MCCodeView includes several llvm/DebugInfo/CodeView headers I guess MC could be made dependent on DebugInfoCodeView? But probably these things should be sunk into BinaryFormat as is the case for DWARF features used by MC? include/llvm/Object/COFF.h includes include/llvm/DebugInfo/CodeView/CVDebugRecord.h Also seems like this could/should/needs to be sunk into BinaryFormat? I'm open to ideas & happy to do the work, or help in any way that might be useful. Tha...

Yes, some of the headers and stuff that are just raw structure definitions and enums could probably be sunk into BinaryFormat.. How'd you find this? Curious why it hasn't been breaking in modules builds for a long time.

Hi all, I am experimenting with extending ELF. I want to add a custom ELF section, something similar to a 'SyntheticSection'. However, I'm not able to find documentation / doxygen for LLD code. Are there any existing examples of adding custom ELF sections at link time in LLVM framework? Is it possible? Any pointers? Thanks in advance!Cheers! -------------- next part -------------- An

Hi All, Following up on https://lists.llvm.org/pipermail/llvm-dev/2020-July/143512.html, and https://reviews.llvm.org/D85408, we would like to consider a design which allows external tools to read the structured contents of the .bb_addr_map section with library calls into an LLVM library. At the same time, we need to have tools/obj2yaml tests in place for bb_addr_map. So it sounds like the

Hi, I was interested in trying out LLVM BOLT and generated profile data using Linux perf using the following: perf record -e cycles:u -o perf.data <command> This is without the use of LBR so I understand the performance improvements may not be much but this was more for becoming familiar with BOLT's commands. I then run: perf2bolt -nl -p perf.data -o perf.fdata <binary> and I
