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.

The expansion of `memref.atomic_rmw` into a `memref.generic_atomic_rmw`
for floating-point min/max operations is no longer necessary as those
are now supported by the LLVM dialect and LLVM IR.
Furthermore, combining this expansion with direct lowering of
`generic_atomic_rmw` could leads to invalid LLVM dialect IR with
`cmpxchg` operating on floating-point values that it does not support.

let constructor is legacy (do not use in tree!) since the tableGen
backend emits most of the glue logic to build a pass.
Note: The following constructor has been retired:
```cpp
std::unique_ptr<Pass> createExpandReallocPass(bool emitDeallocs = true);
```
To update your codebase, replace it with the new options-based API:
```cpp
memref::ExpandReallocPassOptions expandAllocPassOptions{
/*emitDeallocs=*/false};
pm.addPass(memref::createExpandReallocPass(expandAllocPassOptions));
```

Operation memref.reinterpret_cast was accept input like:
%out = memref.reinterpret_cast %in to offset: [%offset], sizes: [10],
strides: [1]
: memref<?xf32> to memref<10xf32>
A problem arises: while lowering, the true offset of %out is %offset,
but its data type indicates an offset of 0. Permitting this
inconsistency can result in incorrect outcomes, as certain pass might
erroneously extract the offset from the data type of %out.
This patch fixes this by enforcing that the return value's data type
aligns
with the input parameter.

This commit adds the mentioned kinds of `AtomicRMWKind`
as well as code generation for them.
|
|
This patch refactors the `AtomicRMWOpConverter` class to use
the dedicated operations from Arith dialect instead of using
`cmpf` + `select` pattern.
Also, a test for `minimumf` kind of `atomic_rmw` has been added.

`minimumf` (#66135)
This patch is part of a larger initiative aimed at fixing floating-point
`max` and `min` operations in MLIR:
https://discourse.llvm.org/t/rfc-fix-floating-point-max-and-min-operations-in-mlir/72671.
This commit renames `maxf` and `minf` enumerators of `AtomicRMWKind`
to better reflect the current naming scheme and the goals of the RFC.

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.

Currently conversions to interfaces may happen implicitly (e.g.
`Attribute -> TypedAttr`), failing a runtime assert if the interface
isn't actually implemented. This change marks the `Interface(ValueT)`
constructor as explicit so that a cast is required.
Where it was straightforward to I adjusted code to not require casts,
otherwise I just made them explicit.

Another mechanical sweep to keep diff small for flip to _Prefixed.
|
|
The Func has a large number of legacy dependencies carried over from the old
Standard dialect, which was pervasive and contained a large number of varied
operations. With the split of the standard dialect and its demise, a lot of lingering
dead dependencies have survived to the Func dialect. This commit removes a
large majority of then, greatly reducing the dependence surface area of the
Func dialect.
|
|
The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:
* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

This is part of splitting up the standard dialect. See https://llvm.discourse.group/t/standard-dialect-the-final-chapter/ for discussion.

These transformations already operate on memref operations (as part of
splitting up the standard dialect). Now that the operations have moved,
it's time for these transformations to move as well.
