PR analyzer/93779 reports an ICE in gfortran with -fanalyzer that was fixed for GCC 10 by a workaround in f76a88ebf089871dcce215aa0cb1956ccc060895; the tree code in question is a FUNCTION_DECL. Given that I want to rework the above patch at some point, it seems prudent to add test coverage to ensure the ICE doesn't come back, which this patch does. gcc/testsuite/ChangeLog: PR analyzer/93779 * gfortran.dg/analyzer/pr88304-2.f90: New test, adapted from gfortran.fortran-torture/compile/pr88304-2.f90
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.
