(FUNCTION_PROFILER): Emit label references corresponding to those generated
by ASM_OUTPUT_INTERNAL_LABEL.
(MOTOROLA, MOTOROLA_BSR, ...): Define #ifndef USE_GAS.
(ASM_SPEC): Define properly #ifdef USE_GAS.
(LIB_SPEC): -L/usr/lib/libp deleted.
(STARTFILE_SPEC): -L/usr/lib/libp added.
(DEFAULT_A_OUT_NAME): Define.
(LINK_SPEC): Pass -v if GNU ld is used.
(LOCAL_LABEL_PREFIX): Local labels start with .L using GAS, else L%.
(USER_LABEL_PREFIX): Undefine.
(FUNCTION_PROFILER): Call asm_fprintf instead of normal fprintf.
(ASM_APP_ON, ASM_FILE_START): GAS supports it.
(CTORS_.../DTORS_...): Define if GNU ld is used.
(ASM_FILE_START): Define properly for Motorola and GNU as syntax.
(TARGET_VERSION): Re-define only #ifndef USE_GAS.
(CALL_USED_REGISTERS): Deleted.
(GLOBAL_ASM_OP): Re-define only #ifndef USE_GAS.
(ASM_{LONG,SHORT,CHAR,BYTE,BYTE_OP}): New macros.
(ASM_OUTPUT_{DOUBLE,LONG_DOUBLE,FLOAT,INT,SHORT}): Use them.
(ASM_OUTPUT_{CHAR,BYTE,ASCII,FLOAT_OPERAND,DOUBLE_OPERAND}): Likewise.
(ALIGN_ASM_OP, SKIP_ASM_OP): New macros.
(ASM_OUTPUT_{ALIGN,SKIP}): Use them.
(ASM_OUTPUT_SOURCE_FILENAME): Define only if not using GNU as.
(ASM_{GENERATE,OUTPUT}_INTERAL_LABEL): Provide proper definitions for
Motorola and GNU as syntax.
(ASM_OUTPUT_ADDR_{VEC,DIFF}_ELT): Changed for portability between
Motorola and GNU as syntax.
(ASM_OUTPUT_{CASE_LABEL,OPCODE}): Define only if not using GNU as.
(ASM_OUTPUT_CASE_FETCH, ASM_RETURN_CASE_JUMP): New macros.
(ASM_OUTPUT_{COMMON,LOCAL}): Proper defns for Motorola and gas syntax.
(SDB_...): Define only for Motorola as.
(ALT_LIBM): New define to tell g++.c about an alternative name for `-lm'.
(MATH_LIBRARY, NEED_ATEXIT, HAVE_ATEXIT, EXIT_BODY): New macros.
