PR analyzer/93379 reports an ICE within region_model::update_for_return_superedge when writing the returned svalue_id to the lhs of the call_stmt The root cause is that this analyzer code assumed that for any call with a non-NULL gimple_call_lhs, the called fndecl would have non-void return type, and thus that a non-null svalue_id would be returned from region_model::pop_frame. This isn't the case e.g. for a call with conflicting types where the callee returns void but the caller assumes int. This patch fixes the ICE by moving the check for null result so that it also guards setting the lhs. gcc/analyzer/ChangeLog: PR analyzer/93379 * region-model.cc (region_model::update_for_return_superedge): Move check for null result so that it also guards setting the lhs. gcc/testsuite/ChangeLog: PR analyzer/93379 * gcc.dg/analyzer/torture/pr93379-2.c: New test. * gcc.dg/analyzer/torture/pr93379.c: New test.

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.
