re PR target/53256 ([avr] Attribute 'interrupt' shall override attribute 'signal')
PR target/53256
* config/avr/elf.h (ASM_DECLARE_FUNCTION_NAME): Remove.
* config/avr/avr-protos.h (avr_asm_declare_function_name): Remove.
* config/avr/avr.h (struct machine_function): Add attributes_checked_p.
* config/avr/avr.c (avr_asm_declare_function_name): Remove.
(expand_prologue): Move initialization of cfun->machine->is_naked,
is_interrupt, is_signal, is_OS_task, is_OS_main from here to...
(avr_set_current_function): ...this new static function.
(TARGET_SET_CURRENT_FUNCTION): New define.
(avr_function_ok_for_sibcall): Use cfun->machine->is_* instead of
checking attributes of current_function_decl.
(avr_regs_to_save): Ditto.
(signal_function_p): Rename to avr_signal_function_p.
(interrupt_function_p): Rename to avr_interrupt_function_p.
* doc/extend.texi (Function Attributes): Better explanation of
'interrupt' and 'signal' for AVR. Move 'ifunc' down to establish
alphabetical order.
