From 3255e512a8594cc5f811aea0dd769429c0f0d614 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Sun, 5 Mar 2017 06:46:38 -0500 Subject: ewah: fix eword_t/uint64_t confusion The ewah subsystem typedefs eword_t to be uint64_t, but some code uses a bare uint64_t. This isn't a bug now, but it's a potential maintenance problem if the definition of eword_t ever changes. Let's use the correct type. Note that we can't use COPY_ARRAY() here because the source and destination point to objects of different sizes. For that reason we'll also skip the usual "sizeof(*dst)" and use the real type, which should make it more clear that there's something tricky going on.
