Subject: [gcc/devel/omp/gcc-11] openmp: Add testcase for threadprivate random access class iterators
Date: Tue, 2 Nov 2021 15:02:03 +0000 (GMT) [thread overview]
Message-ID: <20211102150203.5C60E385843F@sourceware.org> (raw)
https://gcc.gnu.org/g:798ebb8cd58f643baa0579a631f19269a64843dd
commit 798ebb8cd58f643baa0579a631f19269a64843dd
Author: Tobias Burnus <tobias@codesourcery.com>
Date: Tue Nov 2 15:51:22 2021 +0100
openmp: Add testcase for threadprivate random access class iterators
This adds a testcase for random access class iterators. The diagnostics
can be different between templates and non-templates, as for some
threadprivate vars finish_id_expression replaces them with call to their
corresponding wrapper, but I think it is not that big deal, we reject
it in either case.
