| ; This test case tests spilling the CR LT bit on Power10. On Power10, this is |
| ; achieved by setb %reg, %CRREG (lt bit) -> stw %reg, $FI instead of: |
| ; mfocrf %reg, %CRREG -> rlwinm %reg1, %reg, $SH, 0, 0 -> stw %reg1, $FI. |
| |
| ; Without fine-grained control over clobbering individual CR bits, |
| ; it is difficult to produce a concise test case that will ensure a specific |
| ; bit of any CR field is spilled. We need to test the spilling of a CR bit |
| ; other than the LT bit. Hence this test case is rather complex. |
