From: Maciej W. Rozycki Date: Tue, 7 Feb 2017 02:07:21 +0000 (+0000) Subject: PowerPC/BFD: Convert `%P: %H:' to `%H:' in error messages X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=174d0a74a2e6;p=binutils-gdb.git PowerPC/BFD: Convert `%P: %H:' to `%H:' in error messages Remove an inconsistency in BFD linker error messages across the PowerPC backends, where in the presence of line information the `%P: %H:' format sequence makes the first error message produced for any given function different from subsequent ones. Taking the `ld/testsuite/ld-powerpc/tocopt7.s' test case source as an example and the `powerpc-linux' target we have: $ as -gdwarf2 -o tocopt.o -a64 tocopt.s $ ld -o tocopt -melf64ppc tocopt.o ld: tocopt.o: In function `_start': tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction. ld: tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction. $ where the first error message does not have the source file name prefixed with the linker program executable's name, i.e. `ld:', whereas the second error message does, as would any subsequent. This is because with a multiple-line error message such as `%H' produces `%P' only prints the program executable's name on the first line and not any later ones. Also the PowerPC backend is the only part of BFD which uses `%P' along with one of the clever `%C', `%D', `%G', `%H' format specifiers. And last but not least this breaks a GNU Coding Standard's requirement that error messages from compilers should look like this: source-file-name:lineno: message also quoted in `vfinfo' code handling these specifiers. Convert `%P: %H:' to `%H:' in error messages across the PowerPC backends then, yielding: $ as -gdwarf2 -o tocopt.o -a64 tocopt.s $ ld -o tocopt -melf64ppc tocopt.o tocopt.o: In function `_start': tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction. tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction. $ instead, making it consistent and matching the GNU Coding Standard's requirement. bfd/ * elf32-ppc.c (ppc_elf_check_relocs): Use `%H:' rather than `%P: %H:' with `info->callbacks->einfo'.
