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