2025-07-12[llvm] Remove unused includes (NFC) (#148342)Kazu Hirata
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 compiler-specific build failures.
2025-02-14[MLIR][NFC] Return MemRefType in memref.subview return type inference ↵Tomás Longeri
functions (#120024) Avoids the need for cast, and matches the extra build functions, which take a `MemRefType`
2024-12-17[MemRef] Migrate away from PointerUnion::{is,get} (NFC) (#120202)Kazu Hirata
Note that PointerUnion::{is,get} have been soft deprecated in PointerUnion.h: // FIXME: Replace the uses of is(), get() and dyn_cast() with // isa<T>, cast<T> and the llvm::dyn_cast<T> I'm not touching PointerUnion::dyn_cast for now because it's a bit complicated; we could blindly migrate it to dyn_cast_if_present, but we should probably use dyn_cast when the operand is known to be non-null.
2024-04-16[mlir][Interfaces] `Variable` abstraction for `ValueBoundsOpInterface` (#87980)Matthias Springer
This commit generalizes and cleans up the `ValueBoundsConstraintSet` API. The API used to provide function overloads for comparing/computing bounds of: - index-typed SSA value - dimension of shaped value - affine map + operands This commit removes all overloads. There is now a single entry point for each `compare` variant and each `computeBound` variant. These functions now take a `Variable`, which is internally represented as an affine map and map operands. This commit also adds support for computing bounds for an affine map + operands. There was previously no public API for that.
2024-01-17[mlir][IR] Rename "update root" to "modify op" in rewriter API (#78260)Matthias Springer
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`).
2023-09-05[mlir] alloc-to-alloca conversion for memref (#65335)Oleksandr "Alex" Zinenko
Introduce a simple conversion of a memref.alloc/dealloc pair into an alloca in the same scope. Expose it as a transform op and a pattern. Allocas typically lower to stack allocations as opposed to alloc/dealloc that lower to significantly more expensive malloc/free calls. In addition, this can be combined with allocation hoisting from loops to further improve performance.

2023-05-12[mlir] Move casting calls from methods to function callsTres Popp
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. ``` ninja -C $BUILD_DIR clang-tidy run-clang-tidy -clang-tidy-binary=$BUILD_DIR/bin/clang-tidy -checks='-*,misc-cast-functions'\ -header-filter=mlir/ mlir/* -fix rm -rf $BUILD_DIR/tools/mlir/**/*.inc git restore mlir/lib/IR mlir/lib/Dialect/DLTI/DLTI.cpp\ mlir/lib/Dialect/Complex/IR/ComplexDialect.cpp\ mlir/lib/**/IR/\ mlir/lib/Dialect/SparseTensor/Transforms/SparseVectorization.cpp\ mlir/lib/Dialect/Vector/Transforms/LowerVectorMultiReduction.cpp\ mlir/test/lib/Dialect/Test/TestTypes.cpp\ mlir/test/lib/Dialect/Transform/TestTransformDialectExtension.cpp\ mlir/test/lib/Dialect/Test/TestAttributes.cpp\ mlir/unittests/TableGen/EnumsGenTest.cpp\ mlir/test/python/lib/PythonTestCAPI.cpp\ mlir/include/mlir/IR/ ``` Differential Revision: https://reviews.llvm.org/D150123
2023-05-04[mlir][memref] Add helper to make alloca ops independentMatthias Springer
Add a helper function that makes dynamic sizes of `memref.alloca` ops independent of a given set of values. This functionality can be used to make dynamic allocations hoistable from loops. Differential Revision: https://reviews.llvm.org/D149316
