- CodeGen/flatten.c will fail under new PM becausec the new PM AlwaysInliner seems to intentionally inline functions but not call sites marked with alwaysinline (D23299) - Tests that check remarks happen to check them for the inliner which is not turned on at O0. These tests just check that remarks work, but we can make separate tests for the new PM with -O1 so we can turn on the inliner and check the remarks with minimal changes.

// This file tests the -Rpass family of flags (-Rpass, -Rpass-missed
|
|
// and -Rpass-analysis) with the inliner. The test is designed to
|
|
// always trigger the inliner, so it should be independent of the
|
|
// optimization level (under the legacy PM). The inliner is not added to the new
|
|
// PM pipeline unless optimizations are present.
|
|
|
|
// The inliner for the new PM does not seem to be enabled at O0, but we still
|
|
// get the same remarks with at least O1. The remarks are also slightly
|
|
// different and located in another test file.
