--- Comment #2 from HaoChen Gui <guihaoc at gcc dot gnu.org> ---
Sorry, I pasted wrong codes. Here are the correct ones.
//test.c
#include <stdbool.h>
bool foo (int a, int b)
{
if (a > 2)
return false;
if (b < 10)
return true;
return false;
}
//assembly with the trunk
cmpwi 0,3,2
bgt 0,.L3
cmpwi 0,4,9
li 3,1
isel 3,0,3,1
rldicl 3,3,0,63
blr
.p2align 4,,15
.L3:
li 3,0
rldicl 3,3,0,63
blr
The two zero extend (rldicl) are unnecessary?
