From ea82daf4354e45e9b830d9fe58713011c83b07b8 Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Tue, 31 Oct 2017 18:22:23 +0100 Subject: [PATCH] tile: pass machine size to sparse By default, sparse assumes a 64bit machine when compiled on x86-64 and 32bit when compiled on anything else. This can of course create all sort of problems, like issuing false warnings like: 'constant ... is so big it is unsigned long long' or 'shift too big (32) for type unsigned long' when the architecture is 64bit while sparse was compiled on a 32bit machine, or worse, to not emit legitimate warnings in the reverse situation. Fix this by passing to sparse the appropriate -m32/-m64 flag.
