Summary: I made that an unimplemented error, but forgot that it was used for this environment variable.
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.
Introduced in OpenMP 6.0, the device UID shall be a unique identifier of a device on a given system. (Not necessarily a UUID.) Since it is not guaranteed that the (U)UIDs defined by the device vendor libraries, such as HSA, do not overlap with those of other vendors, the device UIDs in offload are always combined with the offload plugin name. In case the vendor library does not specify any device UID for a given device, we fall back to the offload-internal device ID. The device UID can be retrieved using the `llvm-offload-device-info` tool.
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.
Follow-up from #162652 --------- Co-authored-by: Michael Klemm <michael.klemm@amd.com>
Adds omp_target_is_accessible routine. Refactors common code from omp_target_is_present to work for both routines. --------- Co-authored-by: Shilei Tian <i@tianshilei.me>
- ompt_target_data_op_t, ompt_scope_endpoint_t and ompt_target_t are now printed as strings instead of just numbers to ease debugging - some missing clang-format clauses have been added
The failure was reported here: https://github.com/llvm/llvm-project/pull/164039#issuecomment-3425429556 The test was checking for the "bad" behavior so as to keep track of it, but there seem to be some issues with the pointer arithmetic specific to aarch64. The update for now is to not check for the "bad" behavior fully. We may need to debug further if similar issues are encountered eventually once the codegen has been fixed.
