Looking at recent issues, the test/Bindings/Go failure is intermittent on premerge testing for most changes.

The initial checkin was reverted because a lit cfg was missing to exclude non target transform tests of RISCV loop unrolling, should be fixed shortly.

mcberg2021 added a comment to D113798: Add loop unrolling and peeling preferences for RISCV.

I altered the unrolling preferences for the indicated case, we meet the unroll criteria anyways, as the loop is small at the time of evaluation. Also the abort was motioned to the exit block by the time of the evaluation and so is never encountered as a call in the loop. So I think we are ok for this case.

Alex, we have been using these unrolling preferences in house since mid summer for RISC-V. I will have a look at the outlier case too.
