They should have been part of the previous commit 15106. -------------------------------------------------------------------- Add support for the lbarx, lharx, stbcx and sthcs instructions. The instructions are part of the ISA 2.06 but were not implemented in all versions of hardware. The four instructions are all supported in ISA 2.07. The instructions were put under the ISA 2.07 category of supported instructions in this patch. The VEX commit for this fix is r3137. The bugzilla for this issue is 346324. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@15107
