Some of the following testcases ICE, because one of the cpp_get_token calls in builtin_has_include reads the CPP_EOF token but the caller isn't aware that CPP_EOF has been reached and will do another cpp_get_token. get_token_no_padding is something that is use by the has_attribute/has_builtin callbacks, which will first peek and will not consume CPP_EOF (but will consume other tokens). The !SEEN_EOL () check on the other side doesn't work anymore and isn't really needed, as we don't consume the EOF. The change adds one further error to the pr88974.c testcase, if we wanted just one error per __has_include, we could add some boolean whether we've emitted errors already and only emit the first one we encounter (not implemented). 2020-02-04 Jakub Jelinek <jakub@redhat.com> PR preprocessor/93545 * macro.c (cpp_get_token_no_padding): New function. (builtin_has_include): Use it instead of cpp_get_token.

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.
