Subject: s390: Un-swap implementations of VFCH and VFCHE
X-Git-Tag: VALGRIND_3_21_0~226
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=73ab2978f8bfb5becc4bc7356228a117292ca51f;p=thirdparty%2Fvalgrind.git

s390: Un-swap implementations of VFCH and VFCHE

When running under Valgrind, the VFCH instruction behaves like VFCHE, and
vice versa.  Fix this.
