2016-07-27Move make_location from tree.h/c to input.h/cDavid Malcolm2-2/+7
For some reason I added make_location and some related functions to tree.h/c, rather than to input.h/c. Move them there, so we can use them without requiring tree, and add some selftest coverage. gcc/ChangeLog: * input.c (get_pure_location): Move here from tree.c. (make_location): Likewise. Add header comment. (selftest::test_accessing_ordinary_linemaps): Verify pure_location_p, make_location, get_location_from_adhoc_loc and get_range_from_loc. * input.h (get_pure_location): Move declaration here from tree.h. (get_finish): Likewise for inline function. (make_location): Likewise for declaration. * tree.c (get_pure_location): Move to input.c. (make_location): Likewise. * tree.h (get_pure_location): Move declaration to tree.h. (get_finish): Likewise for inline function. (make_location): Likewise for declaration. libcpp/ChangeLog: * include/line-map.h (source_location): Fix line numbers in comment. From-SVN: r238792
2016-07-11input.c: add lexing selftests and a test matrix for line_table statesDavid Malcolm3-12/+19
This patch adds explicit testing of lexing a source file, generalizing this (and the test of ordinary line maps) over a 2-dimensional test matrix covering: (1) line_table->default_range_bits: some frontends use a non-zero value and others use zero (2) the fallback modes within line-map.c: there are various threshold values for source_location/location_t beyond line-map.c changes behavior (disabling of the range-packing optimization, disabling of column-tracking). We exercise these by starting the line_table at interesting values at or near these thresholds. This helps ensures that location data works in all of these states, and that (I hope) we don't have lingering bugs relating to the transition between line_table states. gcc/ChangeLog: * input.c: Include cpplib.h. (selftest::temp_source_file): New class. (selftest::temp_source_file::temp_source_file): New ctor. (selftest::temp_source_file::~temp_source_file): New dtor.

2016-03-09PR c++/70105: prevent nonsensical underline spew for macro expansionsDavid Malcolm3-2/+18
diagnostic_show_locus can sometimes do the wrong thing when handling expressions built up from macros. PR c++/70105 (currently marked as a P3 regression) has an example of a diagnostic where over 500 lines of irrelevant source are printed, and underlined, giving >1000 lines of useless spew to stderr. This patch adds extra sanitization to diagnostic-show-locus.c, so that we only attempt to print underlines and secondary locations if such locations are "sufficiently sane" relative to the primary location of a diagnostic. This "sufficiently sane" condition is implemented by a new helper function compatible_locations_p, which requires such locations to have the same macro expansion hierarchy as the primary location, using linemap_macro_map_loc_unwind_toward_spelling, effectively mimicing the expansion performed by LRK_SPELLING_LOCATION. This may be too strong a condition, but it effectively fixes PR c++/70105, without removing any underlines in my testing.
