Subject: [Qemu-devel] [PATCH] configure: don't apply -O2 if extra-cflags sets -O
Date: Fri, 29 May 2015 11:56:51 +0100 [thread overview]
Message-ID: <1432897012-1423-1-git-send-email-alex.bennee@linaro.org> (raw)
If your trying to debug and want to force -O0 then don't allow the
configure script to try and set -O2. You can use --enable-debug but that
enables a lot more stuff by default.
