[PATCH] D73230: [X86][ELF] Prefer to lower MC_GlobalAddress operands to .Lfoo$local

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

@craig.topper @rnk This is even safer than I thought.

  // clang/lib/CodeGen/CodeGenModule:shouldAssumeDSOLocal
    const auto &CGOpts = CGM.getCodeGenOpts();
    llvm::Reloc::Model RM = CGOpts.RelocationModel;
    const auto &LOpts = CGM.getLangOpts();
    if (RM != llvm::Reloc::Static && !LOpts.PIE)
      return false;

-fpic/-fPIC does not set `dso_local` so this change does not affect that compile model.
