These are identified by misc-include-cleaner. I've filtered out those
that break builds. Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or

[mlir][vector] Standardize base Naming Across Vector Ops (NFC)
This change standardizes the naming convention for the argument
representing the value to read from or write to in Vector ops that
interface with Tensors or MemRefs. Specifically, it ensures that all
such ops use the name `base` (i.e., the base address or location to
which offsets are applied).
Updated operations:
* `vector.transfer_read`,
* `vector.transfer_write`.
For reference, these ops already use `base`:
* `vector.load`, `vector.store`, `vector.scatter`, `vector.gather`,
`vector.expandload`, `vector.compressstore`, `vector.maskedstore`,
`vector.maskedload`.
This is a non-functional change (NFC) and does not alter the semantics of these
operations. However, it does require users of the XFer ops to switch from
`op.getSource()` to `op.getBase()`.
To ease the transition, this PR temporarily adds a `getSource()` interface
method for compatibility. This is intended for downstream use only and should
not be relied on upstream. The method will be removed prior to the LLVM 21
release.
Implements #131602

Turn free-standing `MemRefType`-related helper functions in
`BuiltinTypes.h` into member functions.

This change cleans up call sites. Next step is to mark the member
functions deprecated.

This commit renames 4 pattern rewriter API functions:
* `updateRootInPlace` -> `modifyOpInPlace`
* `startRootUpdate` -> `startOpModification`
* `finalizeRootUpdate` -> `finalizeOpModification`
* `cancelRootUpdate` -> `cancelOpModification`
The term "root" is a misnomer. The root is the op that a rewrite pattern
matches against
(https://mlir.llvm.org/docs/PatternRewriter/#root-operation-name-optional).
A rewriter must be notified of all in-place op modifications, not just
in-place modifications of the root
(https://mlir.llvm.org/docs/PatternRewriter/#pattern-rewriter). The old
function names were confusing and have contributed to various broken
rewrite patterns.
Note: The new function names use the term "modify" instead of "update"
for consistency with the `RewriterBase::Listener` terminology
(`notifyOperationModified`).

- Better documentation.
- Rename interface methods: `source` -> `getSource`, `indices` ->
`getIndices`, etc. to conform with MLIR naming conventions. A default
implementation is not needed.
- Turn many interface methods into helper functions. Most of the
previous interface methods were not meant to be overridden, and if some
were overridden without others, the op would be have been broken.

* Rename functions with underscore to camel case.
* Return C++ bools of "in_bounds" values instead of an `ArrayAttr`.

Currently the transfer splitting patterns will generate an invalid cast
when the source memref for a transfer op has a non-default memory space.
This is handled by first introducing a `memref.memory_space_cast` in
such cases.
Differential Revision: https://reviews.llvm.org/D154515
|
|
* Add `memref::getMixedSize` (same as in the tensor dialect).
* Simplify in-bounds check in `VectorTransferSplitRewritePatterns.cpp` and fix off-by-one error in the static in-bounds check.
* Use "memref::DimOp" instead of `createOrFoldDimOp` when possible.

The old code used to materialize constants as ops, immediately folded them into the resulting affine map and then deleted the constant ops again. Instead, directly fold the attributes into the affine map. Furthermore, all helpers accept `OpFoldResult` instead of `Value` now. This makes the code at call sites more efficient, because it is no longer necessary to materialize a `Value`, just to be able to use these helper functions.
Note: The API has changed (accepts OpFoldResult instead of Value), otherwise this change is NFC.

The MLIR classes Type/Attribute/Operation/Op/Value support
cast/dyn_cast/isa/dyn_cast_or_null functionality through llvm's doCast
functionality in addition to defining methods with the same name.
This change begins the migration of uses of the method to the
corresponding function call as has been decided as more consistent.
Note that there still exist classes that only define methods directly,
such as AffineExpr, and this does not include work currently to support
a functional cast/isa call.
Caveats include:
- This clang-tidy script probably has more problems.
- This only touches C++ code, so nothing that is being generated.
Context:
- https://mlir.llvm.org/deprecation/ at "Use the free function variants
for dyn_cast/cast/isa/…"
- Original discussion at https://discourse.llvm.org/t/preferred-casting-style-going-forward/68443
Implementation:
This first patch was created with the following steps. The intention is
to only do automated changes at first, so I waste less time if it's
reverted, and so the first mass change is more clear as an example to
other teams that will need to follow similar steps.
Steps are described per line, as comments are removed by git:
0. Retrieve the change from the following to build clang-tidy with an
additional check:
https://github.com/llvm/llvm-project/compare/main...tpopp:llvm-project:tidy-cast-check
1. Build clang-tidy
2. Run clang-tidy over your entire codebase while disabling all checks
and enabling the one relevant one. Run on all header files also.
3. Delete .inc files that were also modified, so the next build rebuilds
them to a pure state.
4. Some changes have been deleted for the following reasons:
- Some files had a variable also named cast
- Some files had not included a header file that defines the cast
functions
- Some files are definitions of the classes that have the casting
methods, so the code still refers to the method instead of the
function without adding a prefix or removing the method declaration
at the same time.

Ops that use TypesMatchWith to constrain result types for verification
and to infer result types during parser generation should also be able
to have the `inferReturnTypes` method auto generated. This patch
upgrades the logic for generating `inferReturnTypes` to handle the
TypesMatchWith trait by building a type inference graph where each edge
corresponds to "type of A can be inferred from type of B", supporting
transformers other than `"$_self"`.

The patch adds operations to `BlockAndValueMapping` and renames it to `IRMapping`. When operations are cloned, old operations are mapped to the cloned operations. This allows mapping from an operation to a cloned operation. Example:
```
Operation *opWithRegion = ...
Operation *opInsideRegion = &opWithRegion->front().front();
IRMapping map
Operation *newOpWithRegion = opWithRegion->clone(map);
Operation *newOpInsideRegion = map.lookupOrNull(opInsideRegion);
```
Migration instructions:
All includes to `mlir/IR/BlockAndValueMapping.h` should be replaced with `mlir/IR/IRMapping.h`. All uses of `BlockAndValueMapping` need to be renamed to `IRMapping`.

Ops that were modifed in-place (`finalizeRootUpdate` was called) should be reprocessed by the GreedyPatternRewriter. This is currently not happening with `GreedyRewriteConfig::maxIterations = 1`.
Note: If your project goes into an infinite loop because of this change, you likely have one or multiple faulty patterns that modify the same operations in-place (`updateRootInplace`) indefinitely.

Bufferization already makes the assumption that buffers pass function
boundaries in the strided form and uses the corresponding affine map layouts.
Switch it to use the recently introduced strided layout instead to avoid
unnecessary casts when bufferizing further operations to the memref dialect
counterparts that now largely rely on the strided layout attribute.

After https://reviews.llvm.org/D119743 added the `AutomaticAllocationScope`
trait to loop-like constructs, the vector transfer full/partial splitting pass
started inserting allocations for temporaries within the closest loop rather
than the closest function (or other allocation scope such as `async.execute`).
While this is correct as long as the lowered code takes care of automatic
deallocation at the end of each iteration of the loop, this interferes with
downstream optimizations that expect `alloca`s to be at the function level.
Step over loops when looking for the closest allocation scope in vector
transfer full/partial splitting pass thus restoring the original behavior.

This has been on _Both for a couple of weeks. Flip usages in core with
intention to flip flag to _Prefixed in follow up. Needed to add a couple
of helper methods in AffineOps and Linalg to facilitate a pure flag flip
in follow up as some of these classes are used in templates and so
sensitive to Vector dialect changes.

The revision removes the linalg.fill operation and renames the OpDSL generated linalg.fill_tensor operation to replace it. After the change, all named structured operations are defined via OpDSL and there are no handwritten operations left.
A side-effect of the change is that the pretty printed form changes from:
```
%1 = linalg.fill(%cst, %0) : f32, tensor<?x?xf32> -> tensor<?x?xf32>
```
changes to
```
%1 = linalg.fill ins(%cst : f32) outs(%0 : tensor<?x?xf32>) -> tensor<?x?xf32>
```
Additionally, the builder signature now takes input and output value ranges as it is the case for all other OpDSL operations:
```
rewriter.create<linalg::FillOp>(loc, val, output)
```
changes to
```
rewriter.create<linalg::FillOp>(loc, ValueRange{val}, ValueRange{output})
```
All other changes remain minimal. In particular, the canonicalization patterns are the same and the `value()`, `output()`, and `result()` methods are now implemented by the FillOpInterface.
