--- Comment #4 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:08e803aa9becf407eb7ef7cf6af96e3bd0d02d38 commit r15-9193-g08e803aa9becf407eb7ef7cf6af96e3bd0d02d38 Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Apr 4 08:59:51 2025 +0200 tailc: Use the IPA-VRP tail call hack even for pointers [PR119614] As the first two testcases show, even with pointers IPA-VRP can optimize return values from functions if they have singleton ranges into just the exact value, so we need to virtually undo that for tail calls similarly to integers and floats. The third test just adds check that it works even with floats (which it does). 2025-04-04 Jakub Jelinek <ja...@redhat.com> PR tree-optimization/119614 * tree-tailcall.cc (find_tail_calls): Handle also pointer types in the IPA-VRP workaround. * c-c++-common/pr119614-1.c: New test. * c-c++-common/pr119614-2.c: New test. * c-c++-common/pr119614-3.c: New test.
