In my fix for PR 119318 I put mask calculation in ipcp_bits_lattice::meet_with_1 above a final fix to value so that all the bits in the value which are meaningless according to mask have value zero, which has tripped a validator in PR 119803. This patch fixes that by moving the adjustment down. Even thought the fix for PR 119318 did a similar thing in ipcp_bits_lattice::meet_with, the same is not necessary because that code path then feeds the new value and mask to ipcp_bits_lattice::set_to_constant which does the final adjustment correctly. In both places, however, Jakup proposed a better way of calculating cap_mask and so I have changed it accordingly. gcc/ChangeLog: 2025-04-15 Martin Jambor <mjambor@suse.cz> PR ipa/119803 * ipa-cp.cc (ipcp_bits_lattice::meet_with_1): Move m_value adjustmed according to m_mask below the adjustment of the latter according to cap_mask.

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.
