From 6b5fa0ba4f85a8499287aefaf3f1375450c40c6d Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 19 Nov 2013 16:14:51 -0300 Subject: tools lib traceevent: Fix conversion of pointer to integer of different size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gcc complaint on 32-bit system: /home/acme/git/linux/tools/lib/traceevent/event-parse.c: In function ‘eval_num_arg’: /home/acme/git/linux/tools/lib/traceevent/event-parse.c:3468:9: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] This is because the eval_num_arg returns everything as an 'unsigned long long', so it converts a void pointer to a wider integer, fix it by converting the void pointer to an integer of the same size, 'unsigned long', before casting it to 'unsigned long long'.
