--- Comment #17 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:1931c40364bb9fb0a7c4b650917e3ac0e88bf6f4 commit r14-9185-g1931c40364bb9fb0a7c4b650917e3ac0e88bf6f4 Author: Jakub Jelinek <ja...@redhat.com> Date: Mon Feb 26 17:55:07 2024 +0100 varasm: Handle private COMDAT function symbol reference in readonly data section [PR113617] If default_elf_select_rtx_section is called to put a reference to some local symbol defined in a comdat section into memory, which happens more often since the r14-4944 RA change, linking might fail. default_elf_select_rtx_section puts such constants into .data.rel.ro.local etc. sections and if linker chooses comdat sections from some other TU and discards the one to which a relocation in .data.rel.ro.local remains, linker diagnoses error. References to private comdat symbols can only appear from functions or data objects in the same comdat group, so the following patch arranges using .data.rel.ro.local.pool.<comdat_name> and similar sections. 2024-02-26 Jakub Jelinek <ja...@redhat.com> H.J. Lu <hjl.to...@gmail.com> PR rtl-optimization/113617 * varasm.cc (default_elf_select_rtx_section): For references to private symbols in comdat sections use .data.relro.local.pool.<comdat>, .data.relro.pool.<comdat> or .rodata.<comdat> comdat sections. * g++.dg/other/pr113617.C: New test. * g++.dg/other/pr113617.h: New test. * g++.dg/other/pr113617-aux.cc: New test.
