Subject: Calculate vector element size more directly for VINSERTF128/VEXTRACTF128 immediate... 
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=5141d97d3ee9afca936bc870e67c53e1ed05f790;p=oota-llvm.git

Calculate vector element size more directly for VINSERTF128/VEXTRACTF128 immediate handling. Also use MVT since this only called on legal types during pattern matching.
