The legacy code in vr_values mostly works on integral types (with few exceptions such as some conversions from float). This patch makes vr_values::range_of_expr not die when asked for a range of an unsupported type. It also keeps the min/max simplification code from being called on non integrals, similarly to what many of the other assignment code is doing. This is all a nop on the current code, but will keep us from misbehaving when VRP starts working on non-integrals. Tested on x86-64 Linux. gcc/ChangeLog: * value-query.cc (range_query::get_value_range): Add assert. * vr-values.cc (vr_values::range_of_expr): Make sure we don't ICE on unsupported types in vr_values. (simplify_using_ranges::simplify): Same. |

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.
