[PATCH] D72128: [llvm-objcopy][ELF] Allow setting SHF_EXCLUDE flag for ELF sections

Wed Feb 12 11:20:54 PST 2020

MaskRay added a comment.

Heads-up: GNU objcopy>=2.35 will support `--set-section-flags=exclude`. https://sourceware.org/ml/binutils/2020-02/msg00195.html

The current version does not remove 0x80000000 (SHF_EXCLUDE) when `exclude` is not specified, but it seems that Nick may want to fix this for architectures other than ARM/MIPS/PARISC.
The value 0x80000000 may be unfortunate. `.debug_*.dwo` uses the flag. From the discussions I don't think the llvm-objcopy vs GNU objcopy difference will cause any trouble.
