[llvm] Remove `undef` from `llvm/test/Transforms` tests (#123889)

2025-01-22T14:47:15+00:00

This PR replaces some instances of `undef` with `function argument
value` or `poison` or `concrete values` in several tests under
`llvm/test/Transforms/` directory. These changes align with modern LLVM
standards for better-defined behavior and test determinism. If this
small PR is okay and gets merged, I will work on the rest.

This is inspired by [this
project](https://discourse.llvm.org/t/gsoc-2024-remove-undefined-behavior-from-tests/77236/29),

[NFC] Port an assortment of tests that invoke SROA to new pass manager

[AddDiscriminators] Migrate tests to opaque pointers (NFC)

2022-06-22T10:47:12+00:00

Update performed using:
https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34

memcpy-discriminator.ll was fixed up to use named instructions
and drop the no longer needed bitcasts.

[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.

[NPM] Make AddDiscriminators pass required

2021-09-08T00:02:24+00:00

This is to make sure the pass is not skipped at O0 where optnone is
applied to functions by default.

Revert "[NFC] remove explicit default value for strboolattr attribute in tests"

2021-05-24T17:43:40+00:00

This reverts commit bda6e5bee04c75b1f1332b4fd1ac4e8ef6c3c247.

See https://lab.llvm.org/buildbot/#/builders/109/builds/15424 for instance

[NFC] remove explicit default value for strboolattr attribute in tests

2021-05-24T17:31:04+00:00

Since d6de1e1a71406c75a4ea4d5a2fe84289f07ea3a1, no attributes is quivalent to
setting attribute to false.

This is a preliminary commit for https://reviews.llvm.org/D99080

Migrate function attribute "no-frame-pointer-elim"="false" to "frame-pointer"="none" as cleanups after D56351

Migrate function attribute "no-frame-pointer-elim" to "frame-pointer"="all" as cleanups after D56351

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

2019-04-17T04:52:47+00:00

The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.
