[PATCH] D94072: [MC][ELF] Fix accepting abbreviated form with sh_flags and sh_entsize

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

This now becomes hazy. While `.rodata.cst8` is a built-in section name in MC, it is not in GNU as. i.e. If you specify `.section .rdata.cst8`, GNU as does not make it SHF_MERGE and set sh_entsize to 8.

I think whatever the resolution we take here, you need to fix GCC.

You may need two RUN lines for coverage:

  .ifndef BUILTIN
  .section .rodata.cst8,"aM", at progbits,8
  .endif
  
  .section .rodata.cst8
