From 18c9057f2bc306ccffd85578551cddc83b23b0ae Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Wed, 27 Sep 1995 19:02:16 +0000 Subject: [PATCH] * config/tc-ppc.h (OBJ_XCOFF): Define if OBJ_COFF and not TE_PE. Change OBJ_COFF checks to check OBJ_XCOFF instead. (TARGET_FORMAT): Fully parenthesize. (LEX_QM): Define if TE_PE. * config/tc-ppc.c: Replace OBJ_COFF by OBJ_XCOFF throughout. Remove checks of TE_PE within #ifdef OBJ_XCOFF sections. (init_regtable): Make i unsigned. (ppc_set_current_section): Rename from setCurrentSection. Change all callers. (ppc_arch): Return after as_fatal to avoid gcc warning. (md_assemble): Only declare reloc if OBJ_ELF. Add default to switch on fixups[i].reloc to avoid gcc warning. (IMAGE_SGN_LNK_OTHER): Fix nested comment. (ppc_pe_function): Don't call ppc_canonicalize_symbol_name. (ppc_frob_symbol): Remove TE_PE section checks. (md_estimate_size_before_relax): Return after abort to avoid gcc warning. (md_apply_fix3): Add BFD_RELOC_16_GOT_PCREL to switch. * read.c (LEX_QM): Define as 0 if not defined.
