* config/arm/aout.h: Reformat for improved readability.
* config/arm/arm.h: Reformat for improved readability.
Replace uses of fprintf with asm_fprintf where appropriate.
(ARM_DECLARE_FUNCTION_NAME): New macro: Perform any generic ARM
function declaration assembler actions.
(NUM_INTS): New macro: Convert from bytes to words.
(NUM_REGS): New macro: Compute number of registers required to
hold a quanitity of tyep MODE.
(NUM_REGS2): New macro: Like NUM_REGS but also copes with BLKmode
types.
(NUM_ARG_REGS): New macro: The number of argument registers
available.
(ARG_REGISTER): New macro: Compute the register number of the Nth
argument register.
(LAST_ARG_REGNUM): New macro: The number of the last argument
register.
(SP_REGNUM): New macro: Register number of the stack pointer.
(FP_REGNUM): New macro: Register number of the frame pointer.
(FUNCTION_ARG, FUNCTION_ARG_PARTIAL_NREGS, INIT_CUMULATIVE_AGS,
FUNCTION_ARG_ADVANCE, SETUP_INCOMING_VARARGS): Change
CUMULATIVE_ARGS so that it counts registers not bytes.
* config/arm/arm.c: Rename TARGET_THUMB_INTERWORK to
TARGET_INTERWORK.
Replace uses of fprintf with asm_fprintf where appropriate.
(output_ascii_pseudo_op): Replace with version from thumb.c
* config/arm/coff.h (ASM_FILE_START): Emit ASM_APP_OFF.
* config/arm/elf.h (CPP_PREDEFINES): Replace with
SUBTARGET_CPP_SPEC.
(ASM_DECLARE_FUNCTION_NAME): Use ARM_DECLARE_FUNCTION_NAME.
(ASM_FILE_START): Emit ASM_APP_OFF.
