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.

In pointer_int_sum when called from a SFINAE context, we need to avoid calling size_in_bytes_loc on an incomplete pointed-to type since this latter function isn't SFINAE-enabled and always emits an error on such input. PR c++/103700 gcc/c-family/ChangeLog: * c-common.c (pointer_int_sum): When quiet, return error_mark_node for an incomplete pointed-to type and don't call size_in_bytes_loc. gcc/testsuite/ChangeLog: * g++.dg/template/sfinae32.C: New test.
