Subject: tcg/i386: Fix dupi for avx2 32-bit hosts
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f80d09b599a5e0fd7f44653f23b04104cb703f7a;p=qemu.git

tcg/i386: Fix dupi for avx2 32-bit hosts

The previous change wrongly stated that 32-bit avx2 should have
used VPBROADCASTW.  But that's a 16-bit broadcast and we want a
32-bit broadcast.
