--- Comment #5 from rdapp at linux dot ibm.com --- I would speculate that some of the FAILs are due to the same problem seen in the other PR (104198), i.e. that for the second seq I wrongly assumed that the backend does not recreate the original comparison as well as not read from possibly overwritten regs. Regarding the test failures - in case you don't have anything yet, I could build a vanilla and a patched cross compiler and look and the differences for some of them.
