--- Comment #55 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:4af5de21363cfdd2be227c05dfdee7e053337f6a commit r16-354-g4af5de21363cfdd2be227c05dfdee7e053337f6a Author: Jason Merrill <ja...@redhat.com> Date: Thu May 1 11:40:17 2025 -0400 i386: -Wabi false positive with indirect call [PR60336] This warning relies on the TRANSLATION_UNIT_WARN_EMPTY_P flag (set in cxx_init_decl_processing) to decide whether we want to warn about the GCC 8 empty class parameter passing fix, but in a call through a function pointer we don't have a translation unit and so complain for any -Wabi flag, even now long after this was likely to be relevant. In that situation, let's check the TU for current_function_decl instead. And if we still can't come up with a TU, default to not warning. PR c++/60336 gcc/ChangeLog: * config/i386/i386.cc (ix86_warn_parameter_passing_abi): If no target, check the current TU. gcc/testsuite/ChangeLog: * g++.dg/abi/pr60336-8a.C: New test.
