Don't generate shifts and subtract if have conditional arithmetic. * rtl.h (delete_barrier): New declaration. * jump.c (jump_optimize): Set up to handle conditional call. In conditional arithmetic case, handle CALL_INSN followed by a BARRIER. (delete_barrier): New function. * rtl.c (read_rtx): Call fatal if bad RTL code; check for bad mode. * recog.c (nonmemory_operand): Accept ADDRESSOF. * tree.c (build_type_attribute_variant): Push to obstack of ttype around type_hash_canon call. * expr.c (placeholder_list): Move decl to file scope. (expand_expr): Don't force access to volatile just because its address is taken. If ignoring reference operations, just expand the operands. (expand_expr, case COMPONENT_REF): Propagate EXPAND_CONST_ADDRESS to recursive call when expanding inner. Refine test for using bitfield operations vs pointer punning. (expand_expr, case CONVERT_EXPR): If converting to BLKmode UNION_TYPE from BLKmode, just return inner object. Use proper mode in store_field call. Properly set sizes of object to store and total size in store_field call for convert to union. (expand_expr, case ARRAY_REF): If OP0 is in a register, put it in memory (like for ADDR_EXPR). Also, don't put constant in register if we'll want it in memory. (readonly_fields_p): New function. (expand_expr, case INDIRECT_REF): Call it if LHS. (expand_assignment): Handle a RESULT_DECL where DECL_RTL is a PARALLEL. (do_jump, case WITH_RECORD_EXPR): New case. (get_inner_reference): Always go inside a CONVERT_EXPR and NOP_EXPR if both modes are the same. (store_field): Use bitfield operations if size of bitsize is not same as size of RHS's type. Check for bitpos not a multiple of alignment in BLKmode case. Do block move in largest possible alignment. (store_constructor): Set BITSIZE to -1 for variable size and properly in case of array of BLKmode. (expand_expr_unaligned): New function. (do_compare_and_jump): Call it. * mips/iris5.h (SWITCHES_NEED_SPACES): New macro. * collect2.c (main): Only allow -ofoo if SWITCHES_NEED_SPACES does not include 'o'. * function.c (instantiate_virtual_regs_1, case SET): Handle case where both SET_DEST and SET_SRC reference a virtual register. (gen_mem_addressof): Copy RTX_UNCHANGING_P from new REG to old REG. * integrate.c (expand_inline_function): Handle case of setting virtual stack vars register (from built in setjmp); when parameter lives in memory, expand virtual_{stack_vars,incoming_args}_rtx early. (subst_constant): Add new parm, MEMONLY. (expand_inline_function, integrate_parm_decls): Pass new parm. (integrate_decl_tree): Likewise. (copy_rtx_and_substitute, case MEM): Do copy RTX_UNCHANGING_P. (try_constants): Call subst_constants twice, with MEMONLY 0 and 1. (copy_rtx_and_substitute, case SET): Add explicit calls to copy_rtx_and_substitute for both sides. * stmt.c (expand_asm_operands): Don't use TREE_STRING_LENGTH for constraints. (pushcase{,_range}): Convert to NOMINAL_TYPE after checking for within INDEX_TYPE, instead of before. (fixup_gotos): Use f->target_rtl, not the next insn, since latter may be from a later fixup. (expand_value_return): Correctly convert VAL when promoting function return; support RETURN_REG being a PARALLEL. (expand_return): When checking for result in regs and having cleanup, consider PARALLEL in DECL_RTL as being in regs. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@30299 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | (validate_pattern): Pass along the set for the dest, not a flag. Fix non-lvalue message. Don't warn for VOIDmode SET_DEST of CALL. Check for PC/CC0 as sources. (nodes_identical): Check for children position match before allowing the combination. * rtl.c (read_rtx): Track line number across \\\n. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@30010 138bc75d-0d04-0410-961f-82ee72b054a4
