(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.
