fold_truth_andor_1 via make_bit_field_ref builds an address of a CALL_EXPR which isn't valid GENERIC and later causes an ICE. The following simply avoids the folding for f ().a != 1 || f ().b != 2 as it is a premature optimization anyway. The alternative would have been to build a TARGET_EXPR around the call. To get this far f () has to be const as otherwise the two calls are not semantically equivalent for the optimization. PR middle-end/115641 * fold-const.cc (decode_field_reference): If the inner reference isn't something we can take the address of, fail. * gcc.dg/torture/pr115641.c: New testcase. |

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.
