The following test case (from PR6576):
define i32 @mul(i32 %a, i32 %b) nounwind readnone {
entry:
%cond1 = icmp eq i32 %b, 0 ; <i1> [#uses=1]
br i1 %cond1, label %exit, label %bb.nph
bb.nph: ; preds = %entry
%tmp = mul i32 %b, %a ; <i32> [#uses=1]
ret i32 %tmp
exit: ; preds = %entry
ret i32 0
}
could be reduced to:
define i32 @mul(i32 %a, i32 %b) nounwind readnone {
entry:
%tmp = mul i32 %b, %a
ret i32 %tmp
}
