Fix indentation when location > 5 digits. * diagnostic-show-locus.c (num_digits, num_digits): Move to diagnostic.c to allow it to be utilized by input.c. * diagnostic.c (num_digits, selftest::test_num_digits): Moved here. (selftest::diagnostic_c_tests): Run selftest::test_num_digits. * diagnostic.h (num_digits): Add extern definition. libcpp/ChangeLog: 2018-11-27 Mike Gulick <mgulick@mathworks.com> PR preprocessor/83173 * location-example.txt: Update example -fdump-internal-locations output.

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