From 7c712bbb6c969ae7014707bfddedd821035a2171 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Wed, 1 May 2019 16:51:20 -0700 Subject: Fix code that would trip -Wtype-limits This patch fixes up all code that would throw a -Wtype-limits warning. This sometimes involves eliminating unnecessary checks, adding a few odd but harmless casts or just pragma'ing out the warning for a whole file -- I tried to find the path of least resistance. I think the overall benefit of the warning outweighs the occasional weirdness.
