From ba55bd74360ea4b8b95e73ed79474d37ff482b36 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 9 Jun 2009 20:48:51 +0000 Subject: powerpc: Add configurable -Werror for arch/powerpc Add the option to build the code under arch/powerpc with -Werror. The intention is to make it harder for people to inadvertantly introduce warnings in the arch/powerpc code. It needs to be configurable so that if a warning is introduced, people can easily work around it while it's being fixed. The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed. It's not enabled for math-emu, which is a steaming pile of warnings.
