From 1da68f560dd41ef12f15138fb1b1aff06067f4b7 Mon Sep 17 00:00:00 2001 From: Richard Kenner Date: Sat, 30 Dec 2000 13:10:51 +0000 Subject: alias.c (alias_sets_conflict_p): New function. * alias.c (alias_sets_conflict_p): New function. (mems_in_disjoint_alias_sets_p): Use it. (readonly_fields_p): Moved from expr.c; check for record type. (objects_must_conflict_p): New function. * calls.c (expand_call): Use assign_temp as much as possible, use readonly variant if assigned once, and don't set memory attributes. (emit_library_call_value_1, store_one_arg): Likewise. * integrate.c (expand_inline_function): Likewise. * stmt.c (expand_asm_operands, expand_return): Likewise. * expr.c (copy_blkmode_from_reg, store_constructor): Likewise. (store_field, save_noncopied_parts, expand_expr): Likewise. (expand_expr_unaligned): Likewise. (readonly_fields_p): Moved to alias.c. (safe_from_p): Rework handling of SAVE_EXPR. MEMs ony conflict if alias sets conflict; likewise for INDIRECT_REF. * function.c (struct temp_slot): Delete field ALIAS_SET; add TYPE. (assign_stack_for_temp): Use objects_must_confict_p. Set all memory attributes from type, if specified. (mark_temp_slot): Mark TYPE field. * tree.h (alias_sets_conflict_p, readonly_fields_p): New decls. (objects_must_conflict_p): Likewise. * stmt.c (expand_decl): Don't use assign_stack_temp in error case. (add_case_node): No need to copy nodes anymore.
