From 56a1a3ab449df33268776a8b72a301d3ee67ad8d Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 26 Oct 2015 14:15:25 +0100 Subject: Silence GCC's "cast of pointer to integer of a different size" warning When calculating hashes from pointers, it actually makes sense to cut off the most significant bits. In that case, said warning does not make a whole lot of sense. So let's just work around it by casting the pointer first to intptr_t and then casting up/down to the final integral type.
