[Pass] Add hyphen to some pass names (#74287)

2024-01-25T08:05:54+00:00

Here is the list of the renamed passes:
- `callbrprepare` -> `callbr-prepare`
- `dwarfehprepare` -> `dwarf-eh-prepare`
- `flattencfg` -> `flatten-cfg`
- `loweratomic` -> `lower-atomic`
- `lowerinvoke` -> `lower-invoke`
- `lowerswitch` -> `lower-switch`
- `winehprepare` -> `win-eh-prepare`
- `targetir` -> `target-ir`
- `targetlibinfo` -> `target-lib-info`

Legacy passes are not affected.

[LoopRotate] Convert tests to opaque pointers (NFC)

[test] Switch to use -passes syntax in various test cases

[Tests] Remove explicit -enable-mssa-loop-dependency options (NFC)

2021-08-14T19:21:07+00:00

This is enabled by default. Drop explicit uses in preparation for
removing the option.

Also drop RUN lines that are now the same (typically modulo a
-verify-memoryssa option).

[NewPM][LoopRotate] Rename rotate -> loop-rotate

[LoopPassManager + MemorySSA] Only enable use of MemorySSA for LPMs known to preserve it.

2019-08-21T17:00:57+00:00

Summary:
Add a flag to the FunctionToLoopAdaptor that allows enabling MemorySSA only for the loop pass managers that are known to preserve it.

If an LPM is known to have only loop transforms that *all* preserve MemorySSA, then use MemorySSA if `EnableMSSALoopDependency` is set.
If an LPM has loop passes that do not preserve MemorySSA, then the flag passed is `false`, regardless of the value of `EnableMSSALoopDependency`.

When using a custom loop pass pipeline via `passes=...`, use keyword `loop` vs `loop-mssa` to use MemorySSA in that LPM. If a loop that does not preserve MemorySSA is added while using the `loop-mssa` keyword, that's an error.

Add the new `loop-mssa` keyword to a few tests where a difference occurs when enabling MemorySSA.

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.

This creates non-linear behavior in the inliner (see more details in
r289755's commit thread).
