I think my ideal solution would be LLVM supporting some module metadata such that a section emitted by the backend automatically uses an ELF compressed section, though this wouldn't apply to LTO objects unfortunately. That being said, it's not unreasonable to do this manually for this specified use-case. I see this introduces a new header to the bundled format, will this break any backwards compatibility? I'm guessing old binaries can check for the LLVM bitcode, ELF, or COFF magic directly instead. If that's the case I'd probably recommend adding your magic number to the `file_magic` implementation. https://github.com/llvm/llvm-project/pull/67162 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
