Move make_location from tree.h/c to input.h/c
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 |

input.c: add lexing selftests and a test matrix for line_table states
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.

(ASSERT_EQ_AT): New macro. gcc/testsuite/ChangeLog: * gcc.dg/plugin/location_overflow_plugin.c (plugin_init): Avoid hardcoding the values of LINE_MAP_MAX_LOCATION_WITH_PACKED_RANGES and LINE_MAP_MAX_LOCATION_WITH_COLS. libcpp/ChangeLog: * include/line-map.h (LINE_MAP_MAX_LOCATION_WITH_PACKED_RANGES): Move here from line-map.c.

PR c++/70105: prevent nonsensical underline spew for macro expansions
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. Successfully bootstrapped®rtested in combination with the previous patch on x86_64-pc-linux-gnu; adds 15 new PASS results to g++.sum and 4 new PASS results to gcc.sum. gcc/ChangeLog: PR c/68473 PR c++/70105 * diagnostic-show-locus.c (compatible_locations_p): New function.

Preserve original spellings of extended identifiers.
This patch makes cpplib track the original spellings of extended identifiers, as well as the canonical UTF-8 version, in order to follow standard semantics properly without needing a convoluted and undocumented canonicalization in translation phase 1 (see bug 9449 comments 39-46 regarding such a canonicalization). The spelling is tracked in cpp_identifier and cpp_macro_arg without making cpp_token any larger. The original spelling is used for checks of duplicate macro definitions, stringizing (see the C++ tests added; this case is only an issue for C++ not C because C makes it implementation-defined whether a \ is inserted before the \ of a UCN in a string or character constant when stringizing, while C++ does not), pasting (relevant when the result is then stringized for C++) and when macro definitions are output as text (e.g. for -d options). Once a macro has been defined, only the original spelling of the argument names needs keeping in the argument list. While it is being defined, however, both spellings are needed: the original one for subsequent saving for checks of duplicate macro definitions, and the canonical one which is the node marked specially to generate macro argument tokens rather than normal identifier tokens. The buffer that is used to save the original values of the identifier tokens is changed so that it stores both those original values and a pointer to the canonical hash nodes, so that those canonical nodes can be found when their values need restoring after the macro definition has been parsed. I believe this covers the known standards issues in extended identifiers support (the remaining unimplemented C99 areas in GCC all being floating-point-related), except for C++ translation of extended characters to UCNs in phase 1 (which I have no plans to work on). There are however probably issues left with handling of extended identifiers in other places, as listed in <https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00337.html> (those issues are generally the sort of thing that could be addressed as bugs outside development stage 1). (The bulk of the potential issues Zack was concerned about in 2003-5, that resulted in extended identifiers being disabled in the absence of -fextended-identifiers, were effectively eliminated by the audit and fixes I did in 2009, however; that todo list reflects what was left over after that audit.) Bootstrapped with no regressions on x86_64-unknown-linux-gnu. libcpp: * include/cpp-id-data.h (struct cpp_macro): Update comment regarding parameters. * include/cpplib.h (struct cpp_macro_arg, struct cpp_identifier): Add spelling fields. (struct cpp_token): Update comment on macro_arg. * internal.h (_cpp_save_parameter): Add extra argument. (_cpp_spell_ident_ucns): New declaration. * lex.c (lex_identifier): Add SPELLING argument.

Support location tracking for built-in macro tokens

PR preprocessor/58580 - preprocessor goes OOM with warning for zero literals
In this problem report, the compiler is fed a (bogus) translation unit in which some literals contain bytes whose value is zero. The preprocessor detects that and proceeds to emit diagnostics for that king of bogus literals. But then when the diagnostics machinery re-reads the input file again to display the bogus literals with a caret, it attempts to calculate the length of each of the lines it got using fgets. The line length calculation is done using strlen. But that doesn't work well when the content of the line can have several zero bytes. The result is that the read_line never sees the end of the line because strlen repeatedly reports that the line ends before the end-of-line character; so read_line thinks its buffer for reading the line is too small; it thus increases the buffer, leading to a huge memory consumption and disaster. Here is what this patch does. location_get_source_line is modified to return the length of a source line that can now contain bytes with zero value. diagnostic_show_locus() is then modified to consider that a line can have characters of value zero, and so just shows a white space when instructed to display one of these characters. Additionally location_get_source_line is modified to avoid re-reading each and every line from the beginning of the file until it reaches the line number N that it is instructed to get; this was leading to annoying quadratic behaviour when reading adjacent lines near the end of (big) files. So a cache is now associated to the file opened in text mode. When the content of the file is read, that content is stashed in the file cache. That file cache is searched for line delimiters. A number of line positions are saved in the cache and a number of file caches are kept in memory. That way when location_get_source_line is asked to read line N + 1, it just has to start reading from line N that it has already read. libcpp/ChangeLog: * include/line-map.h (linemap_get_file_highest_location): Declare new function. * line-map.c (linemap_get_file_highest_location): Define it. gcc/ChangeLog: * input.h (location_get_source_line): Take an additional line_size parameter.
