; Check the first five opcodes in the first eviction problem
; Also, the first eviction problem is significantly less than 300 instructions. Check
; that there is a zero value.
; Note: we're regex-ing some of the opcodes to avoid test flakyness.
; CHECK: instructions: 19,{{([0-9]{4})}},12{{([0-9]{2})}},12{{([0-9]{2})}},{{.*}},0,
; Only the candidate virtreg and the 10th LR are included in this problem. Make
; sure the other LRs have values of zero. There are 2700 0s followed by some 1s.
; There's a limit to how many repetitions can be matched.
; CHECK: instructions_mapping: {{(((0,){27}){100})}}
; CHECK-SAME: 1
; Indexing 300 back from where the candidate vr actual resides due to the fact
; that not all the values between the 10th LR and the candidate are zero.

; Ensure that we can still go through the mapping matrices for the rest of the

; There are a total of 23 eviction problems with this test.

; Make sure that we're exporting the mbb_frequencies. Don't actually check
; values due to all values being floating point/liable to change very easily.
; CHECK: mbb_frequencies:
; Make sure that we have the mbb_mapping feature, and that the first couple
; of values are correct.
