From d917662d54ba68d0c3b03e994cb1fa66d7b19c30 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 17 Jun 2014 12:11:45 +0300 Subject: [PATCH] lib.c: skip --param parameters Very dumb patch to just skip --param allow-store-data-races=0 introduced in newer GCC versions. Without this patch sparse recognizes parameter of the --param option as a file name which obviously couldn't be found.
