--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Chung-Lin Tang <clt...@gcc.gnu.org>: https://gcc.gnu.org/g:1c91b014923f418e0aab789c5cf57facf04bf266 commit r12-6890-g1c91b014923f418e0aab789c5cf57facf04bf266 Author: Chung-Lin Tang <clt...@codesourcery.com> Date: Thu Jan 27 18:33:00 2022 +0800 Fix omp-low ICE for indirect references based off component access [PR103642] This issue was triggered after the patch extending syntax for component access in map clauses in commit 0ab29cf0bb68960c1f87405f14b4fb2109254e2f. In gimplify_scan_omp_clauses, the case for handling indirect accesses (which creates firstprivate ptr and zero-length array section map for such decls) was erroneously went into for non-pointer cases (here being the base struct decl), so added the appropriate checks there. Added new testcase is a compile only test for the ICE. The original omptests t-partial-struct test actually should not execute correctly, because for map(t.s->a[:N]), map(t.s[:1]) is not implicitly mapped, thus the entire offloaded access does not work as is (fixing that omptests test is out of scope here). 2022-01-27 Chung-Lin Tang <clt...@codesourcery.com> PR middle-end/103642 gcc/ChangeLog: * gimplify.cc (gimplify_scan_omp_clauses): Do not do indir_p handling for non-pointer or non-reference-to-pointer cases. gcc/testsuite/ChangeLog: * c-c++-common/gomp/pr103642.c: New test.
