    M llvm/test/Analysis/CostModel/X86/mul32.ll

  Log Message:
  -----------
  [CostModel][X86] Pre-SSE41 targets can use PMADDWD for sext sub-i16 -> i32

Without SSE41 sext/zext instructions the extensions will be split, meaning that the MUL->PMADDWD fold will split the sext_i32(x) into zext_i32(sext_i16(x))
