Subject: Disable all optimisation until such time as the 2.3.X route works
X-Git-Tag: svn/VALGRIND_3_0_1^2~951
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=612ee5a502acafa140cd003aca7db8946b2304d4;p=thirdparty%2Fvalgrind.git

Disable all optimisation until such time as the 2.3.X route works
better.  In particular, redundant-Put removal is removing assignments
to x86 guest %esp, which messes up the segfault-based stack extender.
