From d582c98d8f3b1c953a990305ba00201c8c122a55 Mon Sep 17 00:00:00 2001 From: Andy Polyakov Date: Sun, 17 Jan 2010 17:31:38 +0000 Subject: [PATCH] apps/speed.c: limit loop counters to 2^31 in order to avoid overflows in performance calculations. For the moment there is only one code fast enough to suffer from this: Intel AES-NI engine.
