Two improvements:
1. Codegen this comparison:
if (X == 0x8000)
as:
cmplwi cr0, r3, 32768
bne cr0, LBB1_2 ;cond_next
instead of:
lis r2, 0
ori r2, r2, 32768
cmpw cr0, r3, r2
bne cr0, LBB1_2 ;cond_next
2. Codegen this comparison:
if (X == 0x12345678)
as:
xoris r2, r3, 4660
cmplwi cr0, r2, 22136
bne cr0, LBB1_2 ;cond_next
instead of:
lis r2, 4660
ori r2, r2, 22136
cmpw cr0, r3, r2
bne cr0, LBB1_2 ;cond_next
