2014-01-23PR preprocessor/58580 - preprocessor goes OOM with warning for zero literalsDodji Seketeli3-0/+55
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.

gcc/testsuite: * c-c++-common/cpp/ucnid-2011-1.c: New test. libcpp: * ucnid.tab: Add C11 and C11NOSTART data. * makeucnid.c (digit): Rename enum value to N99. (C11, N11, all_languages): New enum values. (NUM_CODE_POINTS, MAX_CODE_POINT): New macros. (flags, decomp, combining_value): Use NUM_CODE_POINTS as array size. (decomp): Use unsigned int as element type. (all_decomp): New array. (read_ucnid): Handle C11 and C11NOSTART. Use MAX_CODE_POINT. (read_table): Use MAX_CODE_POINT. Store all decompositions in all_decomp. (read_derived): Use MAX_CODE_POINT. (write_table): Use NUM_CODE_POINTS. Print N99, C11 and N11 flags. Print whole array variable declaration rather than just array contents. (char_id_valid, write_context_switch): New functions. (main): Call write_context_switch. * ucnid.h: Regenerate. * include/cpplib.h (struct cpp_options): Add c11_identifiers. * init.c (struct lang_flags): Add c11_identifiers. (cpp_set_lang): Set c11_identifiers option from selected language. * internal.h (struct normalize_state): Document "previous" as previous starter character. (NORMALIZE_STATE_UPDATE_IDNUM): Take character as argument. * charset.c (DIG): Rename enum value to N99. (C11, N11): New enum values. (struct ucnrange): Give name to struct. Use short for flags and unsigned int for end of range. Include ucnid.h for whole variable declaration. (ucn_valid_in_identifier): Allow for characters up to 0x10FFFF. Allow for C11 in determining valid characters and valid start characters. Use check_nfc for non-Hangul context-dependent checks. Only store starter characters in nst->previous. (_cpp_valid_ucn): Pass new argument to NORMALIZE_STATE_UPDATE_IDNUM. * lex.c (lex_identifier): Pass new argument to NORMALIZE_STATE_UPDATE_IDNUM. Call NORMALIZE_STATE_UPDATE_IDNUM after initial non-UCN part of identifier. (lex_number): Pass new argument to NORMALIZE_STATE_UPDATE_IDNUM. From-SVN: r204886
