* tree.h (OMP_CLAUSE_LINEAR_GIMPLE_SEQ): Define. * gimplify.c (omp_is_private): Change last argument's type to int. Only diagnose lastprivate if the simd argument is 1, only diagnose linear if the simd argument is 2. (gimplify_omp_for): Adjust omp_is_private callers. When adding lastprivate or private, add the clause to OMP_FOR_CLAUSES. Pass GOVD_EXPLICIT to omp_add_variable. For simd with collapse == 1 create OMP_CLAUSE_LINEAR rather than OMP_CLAUSE_PRIVATE for var. If var != decl and decl is in OMP_CLAUSE_LINEAR, gimplify decl increment to OMP_CLAUSE_LINEAR_GIMPLE_SEQ. * omp-low.c (scan_sharing_clauses, lower_lastprivate_clauses): Handle OMP_CLAUSE_LINEAR_GIMPLE_SEQ. * tree-nested.c (convert_nonlocal_omp_clauses, convert_local_omp_clauses): Handle OMP_CLAUSE_LINEAR. * testsuite/libgomp.c/simd-7.c: New test. * testsuite/libgomp.c/simd-8.c: New test. * testsuite/libgomp.c/simd-9.c: New test. * testsuite/libgomp.c/loop-16.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.
