* gimplify.c (gimplify_omp_for): For #pragma omp for simd iterator not mentioned in clauses use private clause if the iterator is declared in #pragma omp for simd, and when adding lastprivate instead, add it to the outer #pragma omp for too. Diagnose if the variable is private in outer context. For simd collapse > 1 loops, replace all iterators with temporaries. * omp-low.c (lower_rec_input_clauses): Handle LINEAR clause the same even in collapse > 1 loops. gcc/c/ * c-parser.c (c_parser_omp_for_loop): For #pragma omp parallel for simd move lastprivate clause from parallel to for rather than simd. gcc/cp/ * parser.c (cp_parser_omp_for_loop): For #pragma omp parallel for simd move lastprivate clause from parallel to for rather than simd. libgomp/ * testsuite/libgomp.c/for-2.c: Define SC to static for #pragma omp for simd testing. * testsuite/libgomp.c/for-2.h (SC): Define if not defined. (N(f5), N(f6), N(f7), N(f8), N(f10), N(f12), N(f14)): Use SC macro. * testsuite/libgomp.c/simd-14.c: New test. * testsuite/libgomp.c/simd-15.c: New test. * testsuite/libgomp.c/simd-16.c: New test. * testsuite/libgomp.c/simd-17.c: New test. * testsuite/libgomp.c++/for-10.C: Define SC to static for #pragma omp for simd testing. * testsuite/libgomp.c++/simd10.C: New test. * testsuite/libgomp.c++/simd11.C: New test. * testsuite/libgomp.c++/simd12.C: New test. * testsuite/libgomp.c++/simd13.C: New test.
