Detailed Description

Description of a function argument declared with attribute access.
Used as an "iterator" over all such arguments in a function declaration
or call.   

Member Function Documentation

array_as_string()

std::string attr_access::array_as_string

(

tree

type

)

const

Format an array, including a VLA, pointed to by TYPE and used as
a function parameter as a human-readable string.  ACC describes
an access to the parameter and is used to determine the outermost
form of the array including its bound which is otherwise obviated
by its decay to pointer.  Return the formatted string.

free_lang_data()

void attr_access::free_lang_data ( tree attrs )

static

Reset front end-specific attribute access data from ATTRS.
Called from the free_lang_data pass.

from_mode_char()

access_mode attr_access::from_mode_char ( char c )

to_external_string()

tree attr_access::to_external_string

(

)

const

Return the human-readable representation of the external attribute
specification (as it might appear in the source code) as STRING_CST.
External positional arguments are one-based.   

References access_deferred, build_string(), gcc_assert, ggc_alloc(), mode, mode_names, ptrarg, sizarg, and UINT_MAX.

to_internal_string()

tree attr_access::to_internal_string

(

)

const

Return the internal representation as STRING_CST.  Internal positional
arguments are zero-based.   

References build_string(), end, and str.

vla_bounds()

unsigned attr_access::vla_bounds

(

unsigned *

nunspec

)

const

Return the number of specified VLA bounds and set *nunspec to
the number of unspecified ones (those designated by [*]).   

References ggc_alloc(), and str.
