[OpenMP][Flang] Emit default declare mappers implicitly for derived types (#140562)

2025-11-14T15:59:48+00:00

This patch adds support to emit default declare mappers for implicit
mapping of derived types when not supplied by user. This especially
helps tackle mapping of allocatables of derived types.

[PGO][Offload] Fix missing names bug in GPU PGO (#166444)

2025-11-10T16:11:53+00:00

After #163011 was merged, the tests in
[`offload/test/offloading/gpupgo`](https://github.com/llvm/llvm-project/compare/main...EthanLuisMcDonough:llvm-project:gpupgo-names-fix-pr?expand=1#diff-f769f6cebd25fa527bd1c1150cc64eb585c41cb8a8b325c2bc80c690e47506a1)
broke because the offload plugins were no longer able to find
`__llvm_prf_nm`. This pull request explicitly makes `__llvm_prf_nm`
visible to the host on GPU targets and reverses the changes made in
f7e9968a5ba99521e6e51161f789f0cc1745193f.

[OpenMP] Fix tests relying on the heap size variable

2025-11-06T19:00:26+00:00

Summary:
I made that an unimplemented error, but forgot that it was used for this
environment variable.

[Offload] Remove handling for device memory pool (#163629)

2025-11-06T16:15:18+00:00

Summary:
This was a lot of code that was only used for upstream LLVM builds of
AMDGPU offloading. We have a generic and fast `malloc` in `libc` now so
just use that. Simplifies code, can be added back if we start providing
alternate forms but I don't think there's a single use-case that would
justify it yet.

[MLIR][OpenMP] Fix and simplify bounds offset calculation for 1-D GEP offsets (#165486)

2025-10-30T23:54:31+00:00

Currently this is being calculated incorrectly and will result in
incorrect index offsets in more complicated array slices. This PR tries
to address it by refactoring and changing the calculation to be more
correct.

[Offload] XFAIL pgo tests until resolved (#163722)

2025-10-16T09:43:55+00:00

While people look into it, xfail the tests.

[OpenMP] Disable a few more tests to get the bot green (#163614)

2025-10-15T19:14:15+00:00

[OpenMP] Add test to print interop identifiers (#161434)

2025-10-15T18:38:33+00:00

The test covers some of the identifier symbols in the interop runtime.

This test, for now, is to guard against complete breakage, which was the
result of the other `interop.c` test not being enabled on AMD and thus,
not caught by our buildbots.

[Flang][OpenMP] Defer descriptor mapping for assumed dummy argument types (#154349)

2025-10-09T15:52:41+00:00

This PR adds deferral of descriptor maps until they are necessary for
assumed dummy argument types. The intent is to avoid a problem where a
user can inadvertently map a temporary local descriptor to device
without their knowledge and proceed to never unmap it. This temporary
local descriptor remains lodged in OpenMP device memory and the next
time another variable or descriptor residing in the same stack address
is mapped we incur a runtime OpenMP map error as we try to remap the
same address.

This fix was discussed with the OpenMP committee and applies to OpenMP
5.2 and below, future versions of OpenMP can avoid this issue via the
attach semantics added to the specification.

[Flang][OpenMP] Implicitly map nested allocatable components in derived types (#160766)

2025-10-02T16:15:16+00:00

This PR adds support for nested derived types and their mappers to the
MapInfoFinalization pass.

- Generalize MapInfoFinalization to add child maps for arbitrarily
nested allocatables when a derived object is mapped via declare mapper.
- Traverse HLFIR designates rooted at the target block arg and build
full coordinate_of chains; append members with correct membersIndex.

This fixes #156461.
