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. From-SVN: r232379 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
