The use of UOItype with mode(OI) for 16-byte atomic operations is non-standard. The OI mode is not defined in machmode.def and exists only as an ad-hoc construct in libgcc/sync.c. This patch replaces it with UTItype using mode(TI), which is the standard GCC machine mode for 16-byte integers (Tetra Integer). The size argument is also corrected from 8 to 16 to match the actual operand width. libgcc/ChangeLog: * sync.c: Replace UOItype with UTItype and use mode(TI) pass 16, not 8, to DEFINE macro.

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.
