[test] Change test/SampleProfile to use opaque pointers

[test] Change -sample-profile tests to -passes=

so that we can remove SampleProfileLoaderLegacyPass.

[SampleFDO] Add use-sample-profile function attribute.

2020-06-03T00:23:17+00:00

When sampleFDO is enabled, people may expect they can use
-fno-profile-sample-use to opt-out using sample profile for a certain file.
That could be either for debugging purpose or for performance tuning purpose.
However, when thinlto is enabled, if a function in file A compiled with
-fno-profile-sample-use is imported to another file B compiled with
-fprofile-sample-use, the inlined copy of the function in file B may still
get its profile annotated.

The inconsistency may even introduce profile unused warning because if the
target is not compiled with explicit debug information flag, the function
in file A won't have its debug information enabled (debug information will
be enabled implicitly only when -fprofile-sample-use is used). After it is
imported into file B which is compiled with -fprofile-sample-use, profile
annotation for the outline copy of the function will fail because the
function has no debug information, and that will trigger  profile unused
warning.

We add a new attribute use-sample-profile to control whether a function
will use its sample profile no matter for its outline or inline copies.
That will make the behavior of -fno-profile-sample-use consistent.

Revert "Temporarily Revert "Add basic loop fusion pass.""

The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Temporarily Revert "Add basic loop fusion pass."

2019-04-17T02:12:23+00:00

As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

llvm-svn: 358546

Invoke GetInlineCost for legality check before inline functions in SampleProfileLoader.

2017-09-14T17:29:56+00:00

Summary: SampleProfileLoader inlines hot functions if it is inlined in the profiled binary. However, the inline needs to be guarded by legality check, otherwise it could lead to correctness issues.

Do not inline recursive direct calls in sample loader pass.

2017-06-21T17:57:43+00:00

Summary: r305009 disables recursive inlining for indirect calls in sample loader pass. The same logic applies to direct recursive calls.
