; This test case tests spilling the CR EQ bit on Power10. On Power10, this is
; achieved by setb %reg, %CRREG (eq 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.
