testcase for recent dag combiner patch. Before the entry bb was:
_test:
stwu r1, -80(r1)
stw r1, 76(r1)
mflr r11
stw r11, 88(r1)
rlwinm r2, r4, 0, 30, 31
cmplwi cr7, r2, 2
mfcr r2
rlwinm r2, r2, 30, 31, 31
cmplwi cr0, r2, 0
bne cr0, LBB1_2 ;UnifiedReturnBlock
after it is:
_test:
stwu r1, -80(r1)
stw r1, 76(r1)
mflr r11
stw r11, 88(r1)
rlwinm r2, r4, 0, 30, 31
cmplwi cr0, r2, 2
bgt cr0, LBB1_2 ;UnifiedReturnBlock
