The undocumented -fdump-internal-locations option outputs this information
|
|
to stderr, showing what each source_location value means. Source code
|
|
lines are quoted, showing both per-line source_location values and
|
|
per-line&column source_location values (written vertically under the
|
|
corresponding character of source code).
