IR canonicalization: select or bool math?
...mplicit add/sub of the
earlier cases can't be eliminated.
a. define i32 @sel_2_or_1(i1 %a) {
%b = select i1 %a, i32 2, i32 1
ret i32 %b
}
b. define i32 @sel_2_or_1(i1 %a) {
%b = zext i1 to i32 %a
%c = add i32 %b, 1
ret i32 %b
}
6. Does 'sub' make a difference?
a. define i32 @sel_1_or_2(i1 %a) {
%b = select i1 %a, i32 1, i32 2
ret i32 %b
}
b. define i32 @sel_1_or_2(i1 %a) {
%b = zext i1 %a to i32
%c = sub i32 2, %b
ret i32 %c
}
7. Choose between integers that are not consecutive?
a. define i32 @sel_0_or_2(i1 %a) {
%sel = select i1 %a, i32 2, i32 0
ret i32 %sel2
}...
