PR middle-end/53580
	* omp-low.c (scan_omp): Change first argument to
	gimple_seq *, call walk_gimple_seq_mod instead of
	walk_gimple_seq.
	(scan_sharing_clauses, scan_omp_parallel, scan_omp_task,
	scan_omp_for, scan_omp_sections, scan_omp_single,
	execute_lower_omp): Adjust callers.
	(scan_omp_1_stmt): Likewise.  If check_omp_nesting_restrictions
	returns false, replace stmt with GIMPLE_NOP.
	(check_omp_nesting_restrictions): Instead of issuing warnings,
	issue errors and return false if any errors were reported.

	* gcc.dg/gomp/nesting-1.c: Expect errors rather than warnings.
	* gcc.dg/gomp/critical-4.c: Likewise.
	* gfortran.dg/gomp/appendix-a/a.35.1.f90: Likewise.
	* gfortran.dg/gomp/appendix-a/a.35.3.f90: Likewise.
	* gfortran.dg/gomp/appendix-a/a.35.4.f90: Likewise.
	* gfortran.dg/gomp/appendix-a/a.35.6.f90: Likewise.
	* c-c++-common/gomp/pr53580.c: New test.

	* testsuite/libgomp.c/pr26943-2.c: Remove #pragma omp barrier,
	use GOMP_barrier () call instead.
	* testsuite/libgomp.c/pr26943-3.c: Likewise.
	* testsuite/libgomp.c/pr26943-4.c: Likewise.
	* testsuite/libgomp.fortran/vla4.f90: Remove !$omp barrier,
	call GOMP_barrier instead.
	* testsuite/libgomp.fortran/vla5.f90: Likewise.

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.
