--- Comment #1 from David Edelsohn <dje at gcc dot gnu.org> --- I thought that Darwin specifically picked up the definition from config/darwin.h. I don't understand the failure because the rs6000.h logic did not change and rs6000_asm_weaken_decl is declared in rs6000-protos.h. This bug report does not report the actual failure mode, it only provides a patch, so there is no way to review the patch. I only can guess at the problem. Am I to infer that rs6000_asm_weaken_decl function doesn't compile on Darwin because SET_ASM_OP is not defined? Again, Darwin will not actually use the function because the logic was not changed.
