Julian Seward	26f0bb05e7	Be more careful to separate build flags for the preload shared objects ... as opposed to the valgrind code proper. In particular, make sure that -mpreferred-stack-boundary=2 does not get used for the preload shared objects, since that can cause the stack to become misaligned and leads to segfaults. Modified version of a patch from Matthias Schwarzott (zzam@gentoo.org). Fixes #324050. Also, fix the configure check in configure.ac for -mpreferred-stack-boundary=2 so that it checks whether this is allowable for 32-bit code generation even on 64-bit (x86) hosts. This check was wrong before now and led to 32-bit builds on 64-bit hosts generating poorer code for speed critical helper functions (eg helperc_LOADV32le) than on 32-bit builds on 32-bit hosts. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@14471	2014-09-05 20:00:22 +00:00
Julian Seward	b71e8bb6c5	Rename 'exp-ptrcheck' to 'exp-sgcheck' and hope this does not cause ... too much build carnage. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11745	2011-05-11 16:04:28 +00:00
