Fix PR65261 Running bootstrap-ubsan on ppc64le shows many instances of: libcpp/lex.c:552:30: runtime error: load of misaligned address 0x01001f31d37a for type 'const uchar', which requires 16 byte alignment But the unaligned vector loads are intended in this case, because they are preferable to forced-alignment on POWER8. So just silence the ubsan errors. 2015-03-02 Markus Trippelsdorf <markus@trippelsdorf.de> include/ PR target/65261 * ansidecl.h (ATTRIBUTE_NO_SANITIZE_UNDEFINED): New macro. libcpp/ PR target/65261 * lex.c (search_line_fast): Silence ubsan errors.

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.
