From: Jonathan Wakely Date: Tue, 17 Jul 2018 13:18:47 +0000 (+0100) Subject: PR libstdc++/86450 use -Wabi=2 and simplify -Werror use X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c3be340eb67fff7ef353d37bd02898f295ea0ef1;p=gcc.git PR libstdc++/86450 use -Wabi=2 and simplify -Werror use Use -Wabi=2 to fix warnings about -Wabi having no effect on its own. This requires suppressing two warnings in src/c++11/debug.cc which do not affect the library ABI. Previously libstdc++ defaulted to --enable-werror but the -Werror flag was not actually added unless --enable-maintainer-mode was used. This is not documented and not the expected behaviour. This removes any special treatment for maintainer-mode, makes -Werror depend directly on --enable-werror, and changes the default to --enable-werror=no.
