[SDAG] Use BatchAAResults for querying alias analysis (AA) results (#123934)

2025-01-23T09:16:09+00:00

Once we get to SelectionDAG the IR should not be changing anymore, so we
can use BatchAAResults rather than AAResults to cache AA queries.

This should be a NFC change for targets that enable AA during codegen
(such as AArch64), but also give a nice compile-time improvement in some
cases. See:
https://github.com/llvm/llvm-project/pull/123787#issuecomment-2606797041

Note: This follows Nikita's suggestion on #123787.

[NFC][CodeGen] Change CodeGenOpt::Level/CodeGenFileType into enum classes (#66295)

2023-09-14T21:10:14+00:00

This will make it easy for callers to see issues with and fix up calls
to createTargetMachine after a future change to the params of
TargetMachine.

This matches other nearby enums.

For downstream users, this should be a fairly straightforward
replacement,
e.g. s/CodeGenOpt::Aggressive/CodeGenOptLevel::Aggressive
or s/CGFT_/CodeGenFileType::

Revert "[NFC][ScheduleDAG] Remove unused EntrySU SUnit"

2020-09-21T11:33:05+00:00

This reverts commit 0345d88de654259ae90494bf9b015416e2cccacb.

Google internal backend uses EntrySU, we are looking into removing
dependency on it.

[NFC][ScheduleDAG] Remove unused EntrySU SUnit

EntrySU doesn't seem to be used at all when building the ScheduleDAG.

Update the file headers across all of the LLVM projects in the monorepo

2019-01-19T08:50:56+00:00

to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

ScheduleDAG: Cleanup dumping code; NFC

2018-09-19T00:23:35+00:00

- Instead of having both `SUnit::dump(ScheduleDAG*)` and
  `ScheduleDAG::dumpNode(ScheduleDAG*)`, just keep the latter around.
- Add `ScheduleDAG::dump()` and avoid code duplication in several
  places. Implement it for different ScheduleDAG variants.
- Add `ScheduleDAG::dumpNodeName()` in favor of the `SUnit::print()`
  functions. They were only ever used for debug dumping and putting the
  function into ScheduleDAG is consistent with the `dumpNode()` change.
