Wei Mi c9e9384efc [X86] Reduce the width of multiplification when its operands are extended from i8 or i16 ... For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694		2016-06-14 18:53:20 +00:00
