From c899b44807e802c4e87aad1e21be4e93c217966d Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Mon, 30 Aug 2021 19:26:24 +0200 Subject: [PATCH 033/166] Documentation/kcov: Define `ip' in the example. The example code uses the variable `ip' but never declares it. Declare `ip' as a 64bit variable which is the same type as the array from which it loads its value.
