IPA passes redirect some calls in what it determines to be unreachable code to builtin_decl_unreachable. But that function returns sometimes builtin_decl_explicit (BUILT_IN_UNREACHABLE) (which was what GCC 12 and earlier did always), or builtin_decl_explicit (BUILT_IN_TRAP) (e.g. for -funreachable-traps, -O0, -Og). Now the cgraph verification code has a code to verify cgraph edges and has there an exception for these redirections to BUILT_IN_UNREACHABLE, but doesn't have for BUILT_IN_TRAP, so e.g. the following testcase ICEs during that verification. The following patch just adds BUILT_IN_TRAP to those exceptions. 2023-01-27 Jakub Jelinek <jakub@redhat.com> PR ipa/106061 * cgraph.cc (cgraph_edge::verify_corresponds_to_fndecl): Allow redirection of calls to __builtin_trap in addition to redirection to __builtin_unreachable. * gcc.dg/pr106061.c: New test. |

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.
