13.2.2 Function Attributes
The keyword __attribute__ allows you to specify special attributes when making a
declaration. This keyword is followed by an attribute specification inside double
parentheses. The following attributes are currently supported for functions:
address (addr)
alias ("target")
auto_psv, no_auto_psv
boot
const
deprecated
far
format (archetype, string-index, first-to-check)
format_arg (string-index)
interrupt [ ( [ save(list) ] [, irq(irqid) ] [,
altirq(altirqid)] [, preprologue(asm) ] ) ]
keep
naked
near
no_instrument_function
noload
noreturn
round(mode)
save(list)
section ("section-name")
secure
shadow
unsupported("message")
unused
user_init
weak
You may also specify attributes with __ (double underscore) preceding and following
each keyword (e.g., __shadow__ instead of shadow). This allows you to use them in
header files without being concerned about a possible macro of the same name.
Multiple attributes may be specified in a declaration by separating them by commas
within the double parentheses or by immediately following an attribute declaration with
another attribute declaration.
