--- Comment #11 from pthaugen at gcc dot gnu.org ---
Another example to clean up. The back to back constant load/sign extend
sequence of rtl insns is created in each block by the block reordering pass
(.bbo) duplicating the common return block.
int foo(int in)
{
if (in == 1)
return 123;
return 0;
}
foo:
.LFB0:
.cfi_startproc
cmpwi 0,3,1
beq 0,.L5
li 3,0
extsw 3,3
blr
.p2align 4,,15
.L5:
li 3,123
extsw 3,3
blr
