Subject: dis_neon_data_3same: for the case A==12, don't silently produce invalid IR
X-Git-Tag: svn/VALGRIND_3_12_0^2~33
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e429ac1666ec0f00d48c1f610d29af2ff5d1f2e;p=thirdparty%2Fvalgrind.git

dis_neon_data_3same: for the case A==12, don't silently produce invalid IR
which then causes the sanity checker to abort the run.  Instead synthesise
a SIGILL in the normal way.
