--- Comment #1 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- Author: manu Date: Thu Sep 24 16:37:43 2015 New Revision: 228094 URL: https://gcc.gnu.org/viewcvs?rev=228094&root=gcc&view=rev Log: fdiagnostics-color=never does not disable color for some diagnostics Actually, I was trying to reject non-warning options as argument to -Werror=. However, the new test fails because -fdiagnostics-color=never is always placed by the driver after the warning options when calling the compiler proper. This patch prunes all -fdiagnostics-color from the command-line but the last one, which is moved to the first position. gcc/ChangeLog: 2015-09-24 Manuel López-Ibáñez <m...@gcc.gnu.org> PR driver/67640 * opts-common.c (prune_options): Discard all -fdiagnostics-color but the last one, which is moved to the front to be processed first. * opts.c (enable_warning_as_error): Reject options that do not control warnings. gcc/testsuite/ChangeLog: 2015-09-24 Manuel López-Ibáñez <m...@gcc.gnu.org> PR driver/67640 * gcc.dg/Werror-13.c: New test.
