It has been suggested that if we start bumping numbers by an ULP when
calculating open ranges (for example the numbers less than 3.0) that
dumping these will become increasingly harder to read, and instead we
should opt for the hex representation. I still find the floating
point representation easier to read for most numbers, but perhaps we
could have both?
With this patch this is the representation for [15.0, 20.0]:
[frange] float [1.5e+1 (0x0.fp+4), 2.0e+1 (0x0.ap+5)]
Would you find this useful, or should we stick to the hex
representation only?
Tested on x86-64 Linux.
gcc/ChangeLog:
* value-range-pretty-print.cc (vrange_printer::print_real_value): New.
(vrange_printer::visit): Call print_real_value.
* value-range-pretty-print.h: New print_real_value.

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.
