Backport from mainline r215873 2014-10-03 Bill Schmidt * lex.c (search_line_fast): Add new version to be used for Power8 and later targets when Altivec is enabled. Restrict the existing Altivec version to big-endian systems so that lvsr is not used on little endian, where it is deprecated. Remove LE-specific code from the now-BE-only version. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/gcc-4_9-branch@216132 138bc75d-0d04-0410-961f-82ee72b054a4

PR preprocessor/58580 - preprocessor goes OOM with warning for zero literals

2014-01-23T09:13:08+00:00

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.
