3# The post-RA scheduler reorders S2_lsr_r_p and S2_lsr_r_p_or. Both of them
4# use r9, and the last of the two kills it. The kill flag fixup did not
5# correctly update the flag, resulting in both instructions killing r9.

7# CHECK-LABEL: name: foo
8# Check for no-kill of r9 in the first instruction, after reordering:
9# CHECK: $d7 = S2_lsr_r_p_or killed $d7, killed $d1, $r9
10# CHECK: $d13 = S2_lsr_r_p killed $d0, killed $r9
