Since the IPA-CP lattices for value ranges cannot hold more values and don't have any "variable" flag, we initialize them to bottom for non-local nodes. However, that means we don't make use of known information gathered in jump functions when the corresponding node is cloned for some other reason. This patch allows collection of the information and only does not use them for the original non-local nodes, while making sure that we do not propagate information through such-non local nodes as there may be unknown calls. gcc/ChangeLog: 2026-01-06 Martin Jambor <mjambor@suse.cz> * ipa-cp.h (class ipcp_bits_lattice): New members set_recipient_only, recipient_only_p and m_recipient_only. (class ipcp_vr_lattice): Likewise. (ipcp_vr_lattice::init): Initialize also m_recipient_only. * ipa-cp.cc (ipcp_bits_lattice::print): Adjust printting to also print the new flag. (ipcp_vr_lattice::print): Likewise. (ipcp_vr_lattice::set_recipient_only): New function. (ipcp_bits_lattice::set_recipient_only): Likewise. (set_all_contains_variable): New parameter MAKE_SIMPLE_RECIPIENTS, set bits and vr lattices to recibient only insted to bottom when it is true. (initialize_node_lattices): Pass true to the second parameter of set_all_contains_variable. (propagate_bits_across_jump_function): Treat recipient_only source lattices like bottom. (propagate_vr_across_jump_function): Likewise. (ipcp_store_vr_results): Skip non-local nodes.
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.
