This should always be signed chars, so use int8_t. This fixes a miscompile when

[llvm/stm8.git] / test / CodeGen / X86 / subreg-to-reg-3.ll

; RUN: llc < %s -march=x86-64 | grep imull

; Don't eliminate or coalesce away the explicit zero-extension!

define i64 @foo(i64 %a) {

  %c = and i64 %b, 4294967295
  %d = add i64 %c, 1
  ret i64 %d
