omp-low.c (struct omp_context): Add scan_inclusive field.
* omp-low.c (struct omp_context): Add scan_inclusive field. (scan_omp_1_stmt) <case GIMPLE_OMP_SCAN>: Set ctx->scan_inclusive if inclusive scan. (struct omplow_simd_context): Add lastlane member. (lower_rec_simd_input_clauses): Add rvar argument, handle inscan reductions. Build 2 or 3 argument .GOMP_SIMD_LANE calls rather than 1 or 2 argument. (lower_rec_input_clauses): Handle inscan reductions in simd contexts. (lower_lastprivate_clauses): Set TREE_THIS_NOTRAP on the ARRAY_REF. (lower_omp_scan): New function. (lower_omp_1) <case GIMPLE_OMP_SCAN>: Use lower_omp_scan. * tree-ssa-dce.c (eliminate_unnecessary_stmts): For IFN_GOMP_SIMD_LANE check 3rd argument if present rather than 2nd. * tree-vectorizer.h (struct _loop_vec_info): Add scan_map member. (struct _stmt_vec_info): Change simd_lane_access_p from bool into 2-bit bitfield. * tree-vect-loop.c (_loop_vec_info::_loop_vec_info): Initialize scan_map. For IFN_GOMP_SIMD_LANE check 3rd argument if present rather than 2nd. (_loop_vec_info::~_loop_vec_info): Delete scan_map. * tree-vect-data-refs.c (vect_analyze_data_ref_accesses): Allow two different STMT_VINFO_SIMD_LANE_ACCESS_P refs if they have the same init. (vect_find_stmt_data_reference): Encode in ->aux the 2nd IFN_GOMP_SIMD_LANE argument. (vect_analyze_data_refs): Set STMT_VINFO_SIMD_LANE_ACCESS_P from the encoded ->aux value. * tree-vect-stmts.c: Include attribs.h. (vectorizable_call): Adjust comment about IFN_GOMP_SIMD_LANE. (scan_operand_equal_p, check_scan_store, vectorizable_scan_store): New functions. (vectorizable_load): For STMT_VINFO_SIMD_LANE_ACCESS_P tests use != 0. (vectorizable_store): Handle STMT_VINFO_SIMD_LANE_ACCESS_P > 1. cp/ * semantics.c (finish_omp_clauses): For OMP_CLAUSE_REDUCTION_INSCAN set need_copy_assignment. testsuite/ * gcc.dg/vect/vect-simd-8.c: New test. * gcc.dg/vect/vect-simd-9.c: New test. * g++.dg/vect/simd-2.cc: New test. * g++.dg/gomp/scan-1.C: New test.
