GCC modified for the FreeChainXenon project

In IPA-SRA we use can_be_local_p () predicate rather than just plain local call graph flag in order to figure out whether the node is a part of an external API that we cannot change. Although there are cases where this can allow more transformations, it also means we can analyze functions which have no callers at all, which is pointless. Moreover, it makes an assert of hint propagation trigger, which checks that we have looked at callers before processing hints that come from them. This has been reported as PR 110276. This patch simply adds a check that a node has at least one caller into the early checks and makes the node a non-candidate for any transformation if it does not. gcc/ChangeLog: 2023-06-16 Martin Jambor <mjambor@suse.cz> PR ipa/110276 * ipa-sra.cc (struct caller_issues): New field there_is_one.

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.
