--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Kewen Lin <li...@gcc.gnu.org>: https://gcc.gnu.org/g:104864f99c07f87b53c7f45c50a1991b21249489 commit r12-8777-g104864f99c07f87b53c7f45c50a1991b21249489 Author: Kewen.Lin <li...@gcc.gnu.org> Date: Tue Sep 13 04:13:59 2022 -0500 rs6000: Handle unresolved overloaded builtin [PR105485] PR105485 exposes that new builtin function framework doesn't handle unresolved overloaded builtin function well. With new builtin function support, we don't have builtin info for any overloaded rs6000_gen_builtins enum, since they are expected to be resolved to one specific instance. So when function rs6000_gimple_fold_builtin faces one unresolved overloaded builtin, the access for builtin info becomes out of bound and gets ICE then. We should not try to fold one unresolved overloaded builtin there and as the previous support we should emit one error message during expansion phase like "unresolved overload for builtin ...". PR target/105485 gcc/ChangeLog: * config/rs6000/rs6000-builtin.cc (rs6000_gimple_fold_builtin): Add the handling for unresolved overloaded builtin function. (rs6000_expand_builtin): Likewise. gcc/testsuite/ChangeLog: * g++.target/powerpc/pr105485.C: New test. (cherry picked from commit 94504c9ae157db937a2e62d533a36d56598f3c09)
