Ta-Wei Tu 4d9d736875 [NFC] Improve debug message and test description in 4c1f74a 2021-03-24 18:21:13 +08:00
Ta-Wei Tu 4c1f74a76c [LoopFlatten] Fix invalid assertion (PR49571)
The `InductionPHI` is not necessarily the increment instruction, as
demonstrated in pr49571.ll.
This patch removes the assertion and instead bails out from the
`LoopFlatten` pass if that happens.
