X-Git-Tag: svn/VALGRIND_3_8_0~96
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c7048d592126c1cabe78968772c4178cfb2ec5d8;p=thirdparty%2Fvalgrind.git

Add 'aesdec' to the set of insns checked for assembler level SSE4.2
support (Rich Coe) and tidy up a couple of other bits of assembly by
giving them trashed-register lists.
