Jakub Jelinek	804c0f35a6	openmp: OpenMP loop transformation support ... This patch is largely rewritten version of the https://gcc.gnu.org/pipermail/gcc-patches/2023-October/631764.html patch set which I've promissed to adjust the way I'd like it but didn't get to it until now. The previous series together in diffstat was 176 files changed, 12107 insertions(+), 298 deletions(-) This patch is 197 files changed, 10843 insertions(+), 212 deletions(-) and diff between the old series and new patch is 268 files changed, 8053 insertions(+), 9231 deletions(-) Only the 5.1/5.2 tile/unroll constructs are supported, in various places some preparations for the other 6.0 loop transformations constructs (interchange/reverse/fuse) are done, but certainly not complete and not everywhere. The important difference is that because tile/unroll partial map 1:1 the original loops to generated canonical loops and add another set of generated loops without canonical form inside of it, the tile/unroll partial constructs are terminal for the generated loop, one can't have some loops from the tile or unroll partial and some further loops from inside the body of that construct. The GENERIC representation attempts to match what the standard specifies, so there are separate OMP_TILE and OMP_UNROLL trees. If for a particular loop in a loop nest of some OpenMP loop it awaits a generated loop from a nested loop, or if in OMP_LOOPXFORM_LOWERED OMP_TILE/UNROLL construct a generated loop has been moved to some surrounding construct, that particular loop is represented by all NULL_TREEs in the OMP_FOR_{INIT,COND,INCR,ORIG_DECLS} vector. The lowering of the loop transforming constructs is done at gimplification time, at the start of gimplify_omp_for. I think this way it is more maintainable over magic clauses with various loop depths on the other looping constructs or the magic OMP_LOOP_TRANS construct. Though, I admit I'm still undecided how to represent the OpenMP 6.0 loop transformation case of say: #pragma omp for collapse (4) for (int i = 0; i < 32; ++i) #pragma omp interchange permutation (2, 1) #pragma omp reverse for (int j = 0; j < 32; ++j) #pragma omp reverse for (int k = 0; k < 32; ++k) for (int l = 0; l < 32; ++l) ; Surely the i loop would go to first vector elements of OMP_FOR_* of the work-sharing loop, then 2 loops are expecting generated loops from interchange which would be inside of the body. But the innermost l loop isn't part of the interchange, so the question is where to put it. One possibility is to have it in the 4th loop of the OMP_FOR, another possibility would be to add some artificial construct inside of the OMP_INTERCHANGE and 2 OMP_REVERSE bodies which would contain the inner loop(s), e.g. it could be OMP_INTERCHANGE without permutation clause or some artificial ones or whatever. I've recently raised various unclear things in the 5.1/5.2/TRs versions regarding loop transformations, in particular https://github.com/OpenMP/spec/issues/3908 https://github.com/OpenMP/spec/issues/3909 (sorry, private links unless you have OpenMP membership). Until those are resolved, I have a sorry on trying to mix generated loops with non-rectangular loops (way too many questions need to be answered before that can be done) and similarly for mixing non-perfectly nested loops with generated loops (again, it can be implemented somehow, but is way too unclear). The second issue is mostly about data sharing, which is ambiguous, the patch makes the artificial iterators of the loops effectively private in the associated constructs (more like local), but for user iterators doesn't do anything in particular, so for now one needs to use explicit data sharing clauses on the non-loop transformation OpenMP looping constructs or surrounding parallel/task/target etc. 2024-06-05 Jakub Jelinek <jakub@redhat.com> Frederik Harwath <frederik@codesourcery.com> Sandra Loosemore <sandra@codesourcery.com> gcc/ * tree.def (OMP_TILE, OMP_UNROLL): New tree codes. * tree-core.h (enum omp_clause_code): Add OMP_CLAUSE_PARTIAL, OMP_CLAUSE_FULL and OMP_CLAUSE_SIZES. * tree.h (OMP_LOOPXFORM_CHECK): Define.
