From aabab96797a7d61989c25a7ca2b094591bbc74f9 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 17 Jun 2020 13:13:07 -0700 Subject: [PATCH] configure: Disable -Wtautological-type-limit-compare MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Clang 10 enables this by default with -Wtype-limit. All of the instances flagged by this Werror so far have been cases in which we really do want the compiler to optimize away the test completely. Disabling the warning will avoid having to add ifdefs to work around this.
