Subject: x86: slightly simplify VPBROADCASTQ -> VUNPCKLQDQ optimization again
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=333fb2dac903a18fe87eefa932aa87fc6878b630;p=thirdparty%2Fbinutils-gdb.git

x86: slightly simplify VPBROADCASTQ -> VUNPCKLQDQ optimization again

To fix eb4031cb20aa, c117ca0fc276 ("x86: Check XMM destination when
optimizing 128-bit VPBROADCASTQ") should merely have changed which operand
is checked for being Xmmword. Drop the excess check.
