--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:dfd857530e0bda541d4112c5c19bda0567b521ef commit r17-3501-gdfd857530e0bda541d4112c5c19bda0567b521ef Author: Richard Biener <[email protected]> Date: Fri Aug 21 09:36:27 2026 +0200 tree-optimization/126965 - limit recursive PRE expression generation As I've recently figured the PRE value graph can have cycles so when recursively generating a complex expression that should be prone to run into those cycles as well. PR126965 now has a testcase for that, so limit recursinve expression generation. PR tree-optimization/126965 * tree-ssa-pre.cc (find_or_generate_expression): Limit recursion depth. * gcc.dg/tree-ssa/ssa-pre-37.c: New testcase.
