--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:a440b382e43203857de9195eb526c4a16f21ceb1 commit r16-3161-ga440b382e43203857de9195eb526c4a16f21ceb1 Author: Richard Biener <rguent...@suse.de> Date: Tue Aug 12 09:00:48 2025 +0200 tree-optimization/121514 - ICE with recent VN improvement When inserting a compensation stmt during VN we are making sure to register the result for the original stmt into the hashtable so VN iteration has the chance to converge and we avoid inserting another copy each time. But the implementation doesn't work for non-SSA name values, and is also not necessary for constants since we did not insert anything for them. The following appropriately guards the calls to vn_nary_op_insert_stmt as was already done in one place. PR tree-optimization/121514 * tree-ssa-sccvn.cc (visit_nary_op): Only call vn_nary_op_insert_stmt for SSA name result. * gcc.dg/torture/pr121514.c: New testcase.
