[llvm] Teach whole program devirtualization about relative vtables

2023-02-23T22:18:43+00:00

Prior to this patch, WPD was not acting on relative-vtables in C++. This
involves teaching WPD about these things:

- llvm.load.relative which is how relative-vtables are indexed (instead of GEP)
- dso_local_equivalent which is used in the vtable itself when taking the
  offset between a virtual function and vtable
- Update llvm/test/ThinLTO/X86/devirt.ll to use opaque pointers and add
  equivalent tests for RV

[WPD] Add statistics

2022-04-06T01:48:23+00:00

Add statistics to count overall devirtualized targets as well as the
various types of devirtualizations applied at callsites.

[test] Update some test cases to use -passes when specifying the pipeline

2021-09-29T19:51:08+00:00

This updates transform test cases for
  ADCE
  AddDiscriminators
  AggressiveInstCombine
  AlignmentFromAssumptions
  ArgumentPromotion
  BDCE
  CalledValuePropagation
  DCE
  Reg2Mem
  WholeProgramDevirt
to use the -passes syntax when specifying the pipeline.

Given that LLVM_ENABLE_NEW_PASS_MANAGER isn't set to off (which is
a deprecated feature) the updated test cases already used the new
pass manager, but they were using the legacy syntax when specifying
the passes to run. This patch can be seen as a step toward deprecating
that interface.

This patch also removes some redundant RUN lines. Here I am
referring to test cases that had multiple RUN lines verifying both
the legacy "-passname" syntax and the new "-passes=passname" syntax.
Since we switched the default pass manager to "new PM" both RUN lines
have verified the new PM version of the pass (more or less wasting
time running the same test twice), unless LLVM_ENABLE_NEW_PASS_MANAGER
is set to "off". It is assumed that it is enough to run these tests
with the new pass manager now.

Restore "[LTO/WPD] Enable aggressive WPD under LTO option"

2020-01-27T15:55:05+00:00

This restores 59733525d37cf9ad88b5021b33ecdbaf2e18911c (D71913), along
with bot fix 19c76989bb505c3117730c47df85fd3800ea2767.

The bot failure should be fixed by D73418, committed as
af954e441a5170a75687699d91d85e0692929d43.

I also added a fix for non-x86 bot failures by requiring x86 in new test
lld/test/ELF/lto/devirt_vcall_vis_public.ll.

Revert "[LTO/WPD] Enable aggressive WPD under LTO option"

This reverts commit 59733525d37cf9ad88b5021b33ecdbaf2e18911c.

There is a windows sanitizer bot failure in one of the cfi tests
that I will need some time to figure out:
