While working on bitmap operations I figured sanopt.cc uses a sbitmap worklist, iterating using bitmap_first_set_bit on it. That's quadratic since bitmap_first_set_bit for sbitmap is O(n). The fix is to use regular bitmaps for the worklist and the bitmap feeding it and to avoid a useless copy. * sanopt.cc (sanitize_asan_mark_unpoison): Use bitmap for with_poison and alias worklist to it. (sanitize_asan_mark_poison): Likewise. |

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.
