From 3b42bdb47169c617cb79123c407a19d16458b49a Mon Sep 17 00:00:00 2001 From: Nathan Bossart Date: Fri, 16 Feb 2024 14:05:36 -0600 Subject: Use new overflow-safe integer comparison functions. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 6b80394781 introduced integer comparison functions designed to be as efficient as possible while avoiding overflow. This commit makes use of these functions in many of the in-tree qsort() comparators to help ensure transitivity. Many of these comparator functions should also see a small performance boost.
