1 // This test is similar to Frontend/optimization-remark-with-hotness.c but
2 // testing the output under the new pass manager. The inliner is not added to
3 // the default new PM pipeline at O0, so we compile with optimizations here. As
4 // a result, some of the remarks will be different since we turn on inlining,
5 // but the test is meant to show that remarks get dumped. The remarks are also
6 // slightly different in text.
