--- Comment #9 from CVS 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:49d5fb4feee831868d80fff4d024c271911c92ca commit r12-6559-g49d5fb4feee831868d80fff4d024c271911c92ca Author: Andrew MacLeod <amacl...@redhat.com> Date: Wed Jan 12 13:31:08 2022 -0500 Allow more precision when querying from fold_const. fold_const::expr_not_equal_to queries for a current range, but still uses the old value_range class. This is causing it to miss opportunities when ranger can provide something better.
