"[13 Regression]" OpenMP Fortran patches: [Patch] OpenMP/Fortran: Fix loop-iter var privatization with !$OMP LOOP [PR108512] https://gcc.gnu.org/pipermail/gcc-patches/2023-January/610531.html
[Patch][v2] OpenMP/Fortran: Partially fix non-rect loop nests [PR107424] https://gcc.gnu.org/pipermail/gcc-patches/2023-January/610584.html Additionally, there several more patches pending, see below. Of those: The first two small ones are very simple; especially the first one I regard as obvious! The third one is a documentation patch. The others are of varying complexity but I think some would be still suitable for the current stage, including some which have been pinged since October :-( Tobias PS: The mentioned patches: On 10.01.23 12:37, Tobias Burnus wrote:
Hi all, hello Jakub, Below is the updated list to last ping, https://gcc.gnu.org/pipermail/gcc-patches/2022-November/607178.html NOTE to the list below: I have stopped checking older patches. I know some more are pending review, others need to be revised. I will re-check, once the below listed patches have been reviewed. Cf. old list. Thanks for the reviews done in between the last ping and now! * * * Small patches ============= * [Patch] Fortran: Extend align-clause checks of OpenMP's allocate clause https://gcc.gnu.org/pipermail/gcc-patches/2022-December/608401.html Tue Dec 13 16:38:22 GMT 2022 * [Patch] OpenMP: Parse align clause in allocate directive in C/C++ https://gcc.gnu.org/pipermail/gcc-patches/2022-December/608404.html Tue Dec 13 17:44:27 GMT 2022 * Re: [Patch] libgomp.texi: Reverse-offload updates (was: [Patch] libgomp: Handle OpenMP's reverse offloads) https://gcc.gnu.org/pipermail/gcc-patches/2022-December/608245.html Thu Nov 24 12:01:04 GMT 2022 (Side note: wwwdocs also needs to be updated for the latter patch and some other patches done in the meanwhile.) Fortran allocat(e,ors) prep patch ================================= * [Patch] Fortran/OpenMP: Add parsing support for allocators/allocate directive (was: [Patch] Fortran/OpenMP: Add parsing support for allocators directive) https://gcc.gnu.org/pipermail/gcc-patches/2022-December/608904.html Wed Dec 21 15:51:25 GMT 2022 (Remark: While written from scratch, it is kind of a follow-up to Abid's patch [PATCH 1/5] [gfortran] Add parsing support for allocate directive (OpenMP 5.0) you/Jakub reviewed on Tue Oct 11 12:13:14 GMT 2022, i.e. https://gcc.gnu.org/pipermail/gcc-patches/2022-October/603258.html - For the actual implementation of 'allocators', we still have to solve the issues raised in the review for '[PATCH 2/5] [gfortran] Translate allocate directive (OpenMP 5.0).'. at https://gcc.gnu.org/pipermail/gcc-patches/2022-October/603279.html (and earlier in the thread); implementing 'omp allocate' (Fortran/C/C++) seems to be easier but no one has started implementing it so far - only parsing support exists. - The USM patches on semi-USM system run into a similar issue as 'allocators' and for it, some ME omp_allocate is added.) Mapping related patches ======================= (Complex but GCC needs a revision badly as it fixing several bugs and missing functionality.) * Complete patch set was just re-submitted by Julian, overiew patch is [PATCH v6 00/11] OpenMP: C/C++ lvalue parsing, C/C++/Fortran "declare mapper" support https://gcc.gnu.org/pipermail/gcc-patches/2022-December/thread.html#609031 Fri Dec 23 12:12:53 GMT 2022 * Note: For 10/11 of the set, there was a follow up this Monday [PATCH v6 10/11] OpenMP: Support OpenMP 5.0 "declare mapper" directives for C https://gcc.gnu.org/pipermail/gcc-patches/2023-January/609566.html [As it relates to one patch in the series: '[Patch] Fortran/OpenMP: Fix DT struct-component with 'alloc' and array descr' That's mine, needs to be updated (WIP) and fixes array descriptor/alloc-string-length var issues, where descriptor/string length may need to be handled explicitly on data entering map, i.e. string lengths/allocator may require 'to:' instead of 'alloc:' - and on data exit mapping, the current code might add a bogus 'alloc:'. - Idea is to handle this explicitly in fortran/trans-openmp.cc instead of auto-adding it in the ME. Status: WIP - removed in ME but not all cases are handled yet in FE.) Fortran deep mapping (allocatable components) ==================== (Old patch of March 2022, but first part now properly but belated submitted - today): [Patch][1/2] OpenMP: Add lang hooks + run-time filled map arrays for Fortran deep mapping of DT https://gcc.gnu.org/pipermail/gcc-patches/2023-January/609637.html Tobias
