This patch switches us to using LLVM_ENABLE_RUNTIMES rather than using
separate runtimes builds for some reductions in CMake configuration time
and some simplification of the monolithic-linux.sh script.

This patch includes __fwd/span.h in <mdspan> so that we get the
declaration of dynamic_extent inside <mdspan>. We also clean up quite a
few tests that were manually included <span> for dynamic_extent.
This is based on feedback from #142693.

This reorganizes the test coverage for selecting the min/max index. It
adds coverage for umin,umax,smin,smax variants, including test-coverage
for interleave codegen and cost-model driven tests.
The dependency from the type sugar of the underlying type of a Typedef
were not being considered for the dependency of the TypedefType itself.
A TypedefType should be instantiation dependent if it involves
non-instantiated template parameters, even if they don't contribute to
the canonical type.
Besides, a TypedefType should be instantiation dependent if it is
declared in a dependent context, but fixing that would have performance
consequences, as otherwise non-dependent typedef declarations would need
to be transformed during instantiation as well.
This removes the workaround added in

This PR makes `dump-pass-pipeline` pretty-print the dumped pipeline. For
large pipelines the current behavior produces a wall of text that is
hard to visually navigate.
For the command
```bash
mlir-opt --pass-pipeline="builtin.module(flatten-memref, expand-strided-metadata,func.func(arith-expand,func.func(affine-scalrep)))" --dump-pass-pipeline
```
Before:
```bash
Pass Manager with 3 passes:
builtin.module(flatten-memref,expand-strided-metadata,func.func(arith-expand{include-bf16=false include-f8e8m0=false},func.func(affine-scalrep)))
```
After:
```bash
Pass Manager with 3 passes:
builtin.module(
flatten-memref,
expand-strided-metadata,
func.func(
arith-expand{include-bf16=false include-f8e8m0=false},
func.func(
affine-scalrep
)
)
)
```
Another nice feature of this is that the pretty-printed string can still
be copy/pasted into `-pass-pipeline` using a quote:
```bash
$ bin/mlir-opt --dump-pass-pipeline test.mlir --pass-pipeline='
builtin.module(
flatten-memref,
expand-strided-metadata,
func.func(
arith-expand{include-bf16=false include-f8e8m0=false},
func.func(
affine-scalrep
)
)
)'
```

Its presence seems to actively hinder the ToolSubst mechanism that was
supposed to fill in the path to the tool, which prevented these tests
from working on Cygwin.
Now that #141786 handles scalar and neon types, this adds MVE
definitions and legalization for llvm.roundeven intrinsics. The existing
llvm.arm.mve.vrintn are auto-upgraded to llvm.roundeven like other vrint
instructions, so should continue to work.
Linking for Cygwin target always needs -lcygwin (and, -lmsys-2.0
instead for MSYS2 target) but should not auto-export from
them, same as -lmingw32 for MinGW target.
This patch adds to GVN's `propagateEquality()` to reason about equality
constraints through `trunc nuw iN to i1`.
Given:
%tr = trunc nuw iN %v to i1
We can deduce that if `%tr == true`, then `%v == 1`, and if `%tr ==
false`, then `%v == 0`. This is valid because `nuw` guarantees that
truncation didn't lose unsigned bits, so `%v` must have been either 0 or
1.
The patch adds logic to propagate this information via the GVN worklist.
This enables further simplification opportunities downstream, such as
folding redundant stores or conditionals that depend on `%v`.
Includes a test case in `GVN/trunc-nuw-equality.ll`.
Resolves#142744
Allow freeze to sink through fmul by treating it as a
non-poison-generating op
when operands are not poison.
Adding `ISD::FMUL` to `AllowMultipleMaybePoisonOperands` lets DAG
combine
push freeze through fmul. This helps expose patterns like `fmul+fadd`
for `FMA` fusion.
When rebuilding the node, we drop flags like nnan/ninf/nsz that imply
poison,
but keep contract, reassoc, afn, and arcp.
Closes: https://github.com/llvm/llvm-project/issues/141622
This patch removes `inputVecSizesForLeadingDims` from the parameter list
of `createWriteOrMaskedWrite`. That argument is unnecessary - vector
sizes can be obtained from the `vecToStore` parameter. Since this doesn't
change behavior or test results, it's marked as NFC.
Additional cleanups:
* Renamed `vectorToStore` to `vecToStore` for consistency and brevity.
* Rewrote a conditional at the end of the function to use early exit,
improving readability:
```cpp
// BEFORE:
if (maskingRequried) {
Value maskForWrite = ...;
write = maskOperation(write, maskForWrite);
}
return write;
// AFTER
if (!maskingRequried)
return write;
Value maskFroWrite = ...;
return vector::maskOperation(builder, write, maskForWrite);
```
New option AllowNoNamespaceComments for
`google-readability-namespace-comments.AllowNoNamespaceComments` is
added.
When true, the check will allow that no namespace comment is present. If
a namespace comment is added but it is not matching, the check will
fail. Default is `false`
Fixes#124264
This function was a workaround used to detect cyclic dependency
(properly resolved by 343428c666).
We do not want backends to use it. However, #112251 exposed it to MCExpr
to be reused by AMDGPU. Keep the workaround within AMDGPU to prevent
other backends from accidentally relying on it.
Add check for `DeclRefExpr` which points to an explicit object
parameter.
Fixes#141381.
