--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Andrew Macleod <amacl...@gcc.gnu.org>: https://gcc.gnu.org/g:b3327649bffd32af962662dce054b94be2d7330d commit r16-664-gb3327649bffd32af962662dce054b94be2d7330d Author: Andrew MacLeod <amacl...@redhat.com> Date: Wed May 14 11:13:15 2025 -0400 Allow bitmask intersection to process unknown masks. bitmask_intersection should not return immediately if the current mask is unknown. Unknown may mean its the default for a range, and this may interact in intersting ways with the other bitmask. PR tree-optimization/116546 * value-range.cc (irange::intersect_bitmask): Allow unknown bitmasks to be processed.
