In C++, if an iterator has or might have (e.g. dependent type) class type we remember the original init expressions and check those separately for presence of iterators, because for class iterators we turn those into expressions that always do contain reference to the current iterator. But this resulted in rejecting valid non-rectangular loop where the dependent type is later instantiated to an integral type. Non-rectangular loops with class random access iterators remain broken, that is something to be fixed incrementally. 2021-10-27 Jakub Jelinek <jakub@redhat.com> PR c++/102854 gcc/c-family/ * c-common.h (c_omp_check_loop_iv_exprs): Add enum tree_code argument. * c-omp.c (c_omp_check_loop_iv_r): For trees other than decls, TREE_VEC, PLUS_EXPR, MINUS_EXPR, MULT_EXPR, POINTER_PLUS_EXPR or conversions temporarily clear the 3rd bit from d->kind while walking subtrees. (c_omp_check_loop_iv_exprs): Add CODE argument. Or in 4 into data.kind if possibly non-rectangular. gcc/cp/ * semantics.c (handle_omp_for_class_iterator, finish_omp_for): Adjust c_omp_check_loop_iv_exprs caller. gcc/testsuite/ * g++.dg/gomp/loop-3.C: Don't expect some errors. * g++.dg/gomp/loop-7.C: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
