PR preprocessor/69177 and PR c++/68819: libcpp fallbacks and -Wmisleading-indentation
gcc/c-family/ChangeLog:
PR c++/68819
* c-indentation.c (get_visual_column): Add location_t param.
Handle the column number being zero by effectively disabling the
warning, with an "inform".
(should_warn_for_misleading_indentation): Add location_t argument
for all uses of get_visual_column.
gcc/testsuite/ChangeLog:
PR c++/68819
PR preprocessor/69177
* gcc.dg/plugin/location-overflow-test-1.c: New test case.
* gcc.dg/plugin/location-overflow-test-2.c: New test case.
* gcc.dg/plugin/location_overflow_plugin.c: New test plugin.
* gcc.dg/plugin/plugin.exp (plugin_test_list): Add the above.
libcpp/ChangeLog:
PR preprocessor/69177
* line-map.c (LINE_MAP_MAX_LOCATION_WITH_PACKED_RANGES): New
constant.
(LINE_MAP_MAX_LOCATION_WITH_COLS): Add note about unit tests
to comment.
(can_be_stored_compactly_p): Reduce threshold from
LINE_MAP_MAX_LOCATION_WITH_COLS to
LINE_MAP_MAX_LOCATION_WITH_PACKED_RANGES.
(get_combined_adhoc_loc): Likewise.
(get_range_from_loc): Likewise.
(linemap_line_start): Ensure that a new ordinary map is created
when transitioning from range-packing being enabled to disabled,
at the LINE_MAP_MAX_LOCATION_WITH_PACKED_RANGES threshold. Set
range_bits to 0 for new ordinary maps when beyond this limit.
Prevent the "increase the column bits of a freshly created map"
optimization if the range bits has reduced.
