commit r15-4597-g7173e2ff30c1e42168db4ac1dedc12ae1518faab
Author: Andrew MacLeod <amacl...@redhat.com>
Date: Mon Oct 21 18:11:43 2024 -0400
Remove pointer_min_max_operator.
The pointer_min_max_operator class was used before the current dispatch
system was created. These operations have been transferred to
operator_min::fold_range () and operator_max::fold_range () with prange
operands.
This class is no longer used for anything, delete it.
* range-op-ptr.cc (class pointer_min_max_operator): Remove.
(pointer_min_max_operator::wi_fold): Remove.
