From 8efe0ca83eb9c5f996acc7a37d522da5c542ec79 Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Thu, 12 Apr 2012 15:42:19 +0200 Subject: [PATCH] w64: Use uintptr_t in exec.c Replace all type casts to 'long' or 'unsigned long' by 'intptr_t' or 'uintptr_t'. For type casts which are only used to extract the lower bits of an address or to modify those bits, signedness does not matter. There I always use 'uintptr_t'.
