Member Function Documentation

◆ get_key_loc()

location_t string_concat_db::get_key_loc ( location_t loc)
Internal function.  Canonicalize LOC into a form suitable for
use as a key within the database, stripping away macro expansion,
ad-hoc information, and range information, using the location of
the start of LOC within an ordinary linemap.   

References ggc_alloc(), line_table, and NULL.

◆ get_string_concatenation()

bool string_concat_db::get_string_concatenation ( location_t loc,
int * out_num,
location_t ** out_locs )
Determine if LOC was the location of the initial token of a
concatenation of string literal tokens.
If so, *OUT_NUM is written to with the number of tokens, and
*OUT_LOCS with the location of an array of locations of the
tokens, and return true.  *OUT_LOCS is a borrowed pointer to
storage owned by the string_concat_db.
Otherwise, return false.

◆ record_string_concatenation()

void string_concat_db::record_string_concatenation ( int num,
location_t * locs )
Record that a string concatenation occurred, covering NUM
string literal tokens.  LOCS is an array of size NUM, containing the
locations of the tokens.  A copy of LOCS is taken.
