* config/arm/arm.c (arm_init_cumulative_args); New function:
Initlaise the CUMULATIE_ARGS strcuture for a function
defintion.
(arm_function_arg): New function: Determine where to place a
function's argument. Also handles deciding the function's
call cookie.
(current_file_function_operand): New function: Return true if
the symbol is a function which has already been compiled.
(arm_is_long_call_p): New function: Return true if the
indicated function should be called via a long call.
(arm_valid_type_attribute_p): New function: Return true if the
attribute is a valid, arm specific, attribute.
(arm_comp_type_attribute): New function: Return true if the
two types have compatable, arm specific, attributes.
* config/arm/arm.h (CUMULATIVE_ARGS): Redefine to be a
structure.
(FUNCTION_ARG): Redefine to call arm_function_arg.
(FUNCTION_ARG_PARTIAL_NREGS): Redefine to use correct
structure field.
(INIT_CUMULATIVE_ARGS): Redefine to call
arm_init_cumulative_args.
(FUNCTION_ARG_ADVANCE): Redefine to use correct structure
field.
(SETUP_INCOMING_VARARGS): Redefine to use correct structure
field.
(ARM_MARK_NEARBY_FUNCTION): New macro: Mark already compiled
functions.
(ENCODE_SECTION): Add call to ARM_MARK_NEARBY_FUNCTION.
(VALID_MACHINE_TYPE_ATTRIBUTE): Define.
(COMP_TYPE_ATTRIBUTES): Define.
* config/arm/arm.md (call): Call arm_is_long_call_p to decide
if a long call is needed.
(call_value): Call arm_is_long_call_p to decide if a long call
is needed.
(call_symbol): Call arm_is_long_call_p to decide if a long call
is needed.
* config/arm/arm-protos.h: Add prototype for arm_is_long_call_p.
2000-02-11 Denis Chertykov <denisc@overta.ru>
* README.AVR: New file with information about the avr ports.
