--- Comment #3 from Sanjay Patel <spatel+l...@rotateright.com> ---
This fixes the ctlz/cttz parts of this bug:
https://reviews.llvm.org/rL349530
My comments ("all ones") in the description were incorrect - these should be
the correct folds:
define i1 @ctlz_cmp(i32 %a) {
%cmp = icmp slt i32 %a, 0
ret i1 %cmp
}
define i1 @cttz_cmp(i32 %a) {
%1 = and i32 %a, 1
%cmp = icmp ne i32 %1, 0
ret i1 %cmp
}
