The depend-iterator-3.C testcases shows various bugs.
1) tsubst_omp_clauses didn't handle OMP_CLAUSE_AFFINITY (should be
handled like OMP_CLAUSE_DEPEND)
2) because locators can be arbitrary lvalue expressions, we need
to allow for C++ array section base (especially when array section
is just an array reference) FIELD_DECLs, handle them as this->member,
but don't need to privatize in any way
3) similarly for this as base
4) depend(inout: this) is invalid, but for different reason than the reported
one, again this is an expression, but not lvalue expression, so that
should be reported
5) the ctor/dtor cloning in the C++ FE (which is using walk_tree with
copy_tree_body_r) didn't handle iterators correctly, walk_tree normally
doesn't walk TREE_PURPOSE of TREE_LIST, and in the iterator case
that TREE_VEC contains also a BLOCK that needs special handling during
copy_tree_body_r

* tree-inline.c (copy_tree_body_r): Handle iterators on
OMP_CLAUSE_AFFINITY or OMP_CLAUSE_DEPEND.

after depend only cases.

* semantics.c (handle_omp_array_sections_1): For
OMP_CLAUSE_{AFFINITY,DEPEND} handle FIELD_DECL base using
finish_non_static_data_member and allow this as base.
(finish_omp_clauses): Move OMP_CLAUSE_AFFINITY
after depend only cases. Let this be diagnosed by !lvalue_p
case for OMP_CLAUSE_{AFFINITY,DEPEND} and remove useless
assert.
* pt.c (tsubst_omp_clauses): Handle OMP_CLAUSE_AFFINITY.

* g++.dg/gomp/this-1.C: Don't expect any diagnostics for
this as base expression of depend array section, expect a different
error wording for this as depend locator and add testcases
for affinity clauses.

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.
