ipa: Rationalize IPA-VR computations across pass-through jump functions
Currently ipa_value_range_from_jfunc and
propagate_vr_across_jump_function contain similar but not same code
for dealing with pass-through jump functions.  This patch puts these
common bits into one function which can also handle comparison
operations.

gcc/ChangeLog:

2024-11-01  Martin Jambor  <mjambor@suse.cz>

	PR ipa/114985
	* ipa-cp.cc (ipa_vr_intersect_with_arith_jfunc): New function.
	(ipa_value_range_from_jfunc): Move the common functionality to the
	above new function, adjust the rest so that it works with it well.
	(propagate_vr_across_jump_function): Likewise.

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.
