Extends reduction support for `do concurrent`, in particular, for
associating names. Consider the following input:
```fortran
subroutine dc_associate_reduce
integer :: i
real, allocatable, dimension(:) :: x
associate(x_associate => x)
do concurrent (i = 1:10) reduce(+: x_associate)
end do
end associate
end subroutine
```
The declaration of `x_associate` is emitted as follows:
```mlir
%13:2 = hlfir.declare %10(%12) {uniq_name = "...."} : (!fir.heap<!fir.array<?xf32>>, !fir.shapeshift<1>) -> (!fir.box<!fir.array<?xf32>>, !fir.heap<!fir.array<?xf32>>)
```
where the HLFIR base type is an array descriptor (i.e. the
allocatable/heap attribute is dropped as stipulated by the spec; section
11.1.3.3).
The problem here is that `declare_reduction` ops accept only reference
types. This restriction is already partially handled for
`fir::BaseBoxType`'s by allocating a stack slot for the descriptor and
storing the box in that stack allocation. We have to modify this a
littble bit for `associate` since the HLFIR and FIR base types are
different (unlike most scenarios).
This PR adds a summary and synthetic children for `std::unique_ptr` from MSVC's STL ([NatVis](https://github.com/microsoft/STL/blob/313964b78a8fd5a52e7965e13781f735bcce13c5/stl/debugger/STL.natvis#L285-L303)). As with libc++, the deleter is only shown if it's non-empty. Tested both the shared_ptr and unique_ptr tests on Windows. Towards #24834.
Make the option visible, improve the help text, and add a release note.
At this time (immediately prior to llvm21 branching) we haven't instrumented coroutine generation to identify the "key" instructions of things like co_return and similar. This will lead to worse stepping behaviours, as there won't be any key instruction for those lines. This patch removes the key-instructions flag from the DISubprograms for coroutines, which will cause AsmPrinter to use the "old" / existing linetable stepping behaviour, avoiding a regression until we can instrument these constructs. (I'm going to post on discourse about whether this is a good idea or not in a moment)
…(#148600) Ran my python script from llvm/llvm-project#97043 over the repo again and there was 1 duplicate test-case that has been introduced since I last did this. This patch renames that test.
Update the Neoverse V2 Scheduler to reflect the correct latencies along with having updated the relevant mca tests.
…e vectors. (#148351) Fixes llvm/llvm-project#148347
Add a couple of patterns to generate the Xqciac QC_SHLADD shift left and add immediate instruction.
This was obsoleted by ed1ee9a
At the missing `spirv::ImageFetchOp` operation to the SPIR-V MLIR dialect ODS with appropriate testing including negative testing of the verifiers. Signed-off-by: Jack Frankland <[email protected]>
…#148552) Fix a false positve warning which was introduced by #146234.
`f128` intrinsic functions from libm sometimes lower to `long double` library calls when they instead need to be `f128` versions. Add a generic test demonstrating current behavior.
When `EnumRec::isTyped()` is true, include the `EnumValueRec::getTaggedType()` to the documentation.
In the transform dialect tutorial chapter 1, there were some errors that prevented the example from running. This PR fixes them. --------- Co-authored-by: Renato Golin <[email protected]>
Update test with all zero constant input values which get folded during IR construction to actually use different input values, which require materializing build vectors.
…tion (#148614) This is done by other backends at the start of this function, for example AArch64Disassembler::getInstruction. Not setting it means you hit asserts in MCDisassembler::tryAddingSymbolicOperand and MCDisassembler::tryAddingPcLoadReferenceComment when there is a symbolizer set. Which happened to me while debugging a SystemZ program using LLDB. As the only good way to hit this path is from C++, I've copied X86's disassembler unit tests and added just enough to hit an assert if the comment stream is not set.
Preserve the argument-clause for `warn-unused-result` when under clang:: scope. We are not touching gnu:: scope for now as it's an error for GCC to have that string. Personally I think it would be ok to relax it here too as we are not introducing breakage to currently passing code, but feedback is to go slowly about it.
Split out the calls to __builtin_verbose_trap into a separate header. This is just a refactoring to make the code a bit more structured.
… (#148565) If I understand correctly there was a point where we used to need this before it was implied by Zvl*b. Now that it is though and we use -mattr=+v in pretty much every test we can remove it. In unroll-in-loop-vectorizer.ll we can force a VF of 1 instead by using -force-vector-width=1, and in scalable-basics.ll the two RUN lines were the same so I merged them.
Allows expand of sdiv->mul by constant combine for the general case. Previously this was only occurring in the exact case. This is part of the resolution to issue #118090
Our setup runs tests with bazel in such a way that the work tree is readonly, which was causing this test to fail because it couldn't write the .o file. This fixes that, which was new in 15c3793 when this test was introduced.
…__support/math folder. (#147895) Part of #147386 in preparation for: https://discourse.llvm.org/t/rfc-make-clang-builtin-math-functions-constexpr-with-llvm-libc-to-support-c-23-constexpr-math-functions/86450
Add `OffloadDeviceTest::getPlatformBackend()` and use it to skip event tests which currently fail on AMDGPU due to: ``` OL_ERRC_UNIMPLEMENTED: synchronize event not implemented ```
This patch contains fixes for various nits mentioned in #147200: - This patch removes the `bit.` prefix in the op mnemonic. The operation names now directly correspond to the builtin function names except for `bswap` which is represented by `cir.byte_swap` for more clarity. - Since all bit operations are `SameOperandsAndResultType`, this patch updates their assembly format and avoids spelling out the operand type twice.
In #125921, the changes requested by P2372R3 were completed and tested together with corresponding `chrono` types. But that PR didn't mention P2372R3. The `__cpp_lib_format` FTM was even bumped by an earlier PR #98275. This PR confirms that P2372R3 was completed in LLVM 21 (together with P1361R2). Closes #100043
To allow all C++ features in constexpr contexts we need to track constexpr initializers of variables. The mentioned commit moved some code to handle consteval better but we need the code where it used to be since it is not only consteval that we care about.
The difference is additional passes: FPBuiltinFnSelectionPass
27c9b55 was added upstream, but because it has limited SYCL support, tests can't run properly.

sycl-e2e is failing in for cuda in HandleVirtRegUse. @intel/llvm-reviewers-cuda Can we get someone to have a look? Thanks! Simple reproducer is: |
Never mind, I had a look myself and found the fix. :) |
We may still need to keep CopyToReg even after folding uses into vector loads, since the original register may be used in other blocks. Partially reverts 1fdbe69

This is ready for review.
