(FENCE_FOLLOWING_MOVNT): New macro. (struct mem_ref): Add independent_p and storent_p fields. (record_ref): Initalize the new fields. (gather_memory_references_ref): Return true if the reference could be analysed. (gather_memory_references): Check whether all memory accesses in loop were recorded. (should_issue_prefetch_p): Return false for nontemporal stores. (nontemporal_store_p, mark_nontemporal_store, emit_mfence_after_loop, may_use_storent_in_loop_p, mark_nontemporal_stores): New functions. (determine_loop_nest_reuse): Detect independent memory references. (loop_prefetch_arrays): Call mark_nontemporal_stores. * tree-flow.h (mark_virtual_ops_for_renaming): Declare. * Makefile.in (tree-ssa-loop-prefetch.o): Add OPTABS_H dependency. * config/i386/i386.h (x86_mfence): Declare. (FENCE_FOLLOWING_MOVNT): Return x86_mfence. * config/i386/i386.c (x86_mfence): New variable. (ix86_init_mmx_sse_builtins): Initialize x86_mfence. * tree-pretty-print.c (dump_generic_node): Mark nontemporal stores. * optabs.c (init_optabs): Initialize storent_optab. * optabs.h (enum optab_index): Add OTI_storent. (storent_optab): Declare. * genopinit.c (optabs): Add initialization for storent_optab. * tree.h (MOVE_NONTEMPORAL): New macro. * expr.c (expand_assignment, store_expr, store_constructor_field, store_constructor, store_field, expand_expr_real_1): Propagate nontemporality of the expanded store. (emit_storent_insn): New function. * expr.h (expand_assignment, store_expr): Declaration changed. * function.c (assign_parm_setup_reg): Pass false as nontemporality to expand_assignment. * stmt.c (expand_asm_expr): Ditto. * calls.c (initialize_argument_information): Pass false as nontemporality to store_expr. * config/i386/sse.md (storentv4sf, storentv2df, storentv2di, storentsi): New. * gcc.dg/tree-ssa/prefetch-7.c: New test.
