Subject: AVX: Add additional vbroadcast replacement sequences for integers.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7bc9698f3a5e9ebfc85214c5e75261edf35809e5;p=oota-llvm.git

AVX: Add additional vbroadcast replacement sequences for integers.
Remove the v2f64 patterns because it does not match any vbroadcast
instruction.
