[Transforms] Convert some tests to opaque pointers (NFC)

2023-01-05T11:43:45+00:00

These are all tests where conversion worked automatically, and
required no manual fixup.

[test] Fix LoopFusion tests under NewPM

2020-12-08T01:37:42+00:00

The legacy pass depended on -loop-simplify running. The NPM does not
allow for a non-analysis pass to depend on another non-analysis pass.

[LoopFusion] Restrict loop fusion to rotated loops.

2019-12-16T20:17:29+00:00

Summary:
This patch restricts loop fusion to only consider rotated loops as valid candidates.
This simplifies the analysis and transformation and aligns with other loop optimizations.

Add basic loop fusion pass.

2019-04-17T18:53:27+00:00

This patch adds a basic loop fusion pass. It will fuse loops that conform to the
following 4 conditions:
  1. Adjacent (no code between them)
  2. Control flow equivalent (if one loop executes, the other loop executes)
  3. Identical bounds (both loops iterate the same number of iterations)
  4. No negative distance dependencies between the loop bodies.

The pass does not make any changes to the IR to create opportunities for fusion.
Instead, it checks if the necessary conditions are met and if so it fuses two
loops together.

The pass has not been added to the pass pipeline yet, and thus is not enabled by
default. It can be run stand alone using the -loop-fusion option.

The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.
