We have a chance for an optimization. Consider this code:
[oota-llvm.git]
/
test
/
CodeGen
/
ARM
/
mvncc.ll

; RUN: llc < %s -mtriple=arm-apple-darwin | FileCheck %s

define i32 @f1(i32 %t) nounwind {
4
; CHECK: f1
5
; CHECK-NOT: tst
6
; CHECK: and
7
; CHECK: mvnne
8
%and = and i32 %t, 256
9
%tobool = icmp eq i32 %and, 0
10
%retval.0 = select i1 %tobool, i32 0, i32 -26
11
ret i32 %retval.0

}
