[PATCH] D109234: [PGO] Change ThinLTO test for targets with loop unrolling disabled

[Sherwin via Phabricator via cfe-commits]

sherwin-dc added a comment.

I have changed the unroll and icp tests to instead look at the passes that were run, which are shown with the `-mllvm -opt-bisect-limit=-1` flag. This should allow checking that the Loop Unrolling and Indirect Call Promotion passes are run with samplepgo but not thinlto.

To clarify, the backend that I am working on does not disable the Loop Unrolling pass from running, but uses target hooks within the pass to stop the loop from being unrolled, hence this would work for targets that would choose to disable loop unrolling in this way.

The bottom 2 tests are combined together now because of the way the passes are printed out. Though if there is a better way of arranging the tests please let me know. For reference this is what the output looks like:
