Subject: Add the "vbroadcasti128" instruction back.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9814f7b92cbea6f4912f84b0c388541bdcebd529;p=oota-llvm.git

Add the "vbroadcasti128" instruction back.

This is a follow-up to r231182. This adds the "vbroadcasti128" instruction
back, but without the intrinsic mapping. Also add a test to check the
instriction encoding.

This is related to rdar://problem/18742778.
