From d05ef53cbd08972f89bd13e8ce2739de68965a05 Mon Sep 17 00:00:00 2001 From: Christopher Head Date: Fri, 14 Jun 2019 15:35:31 -0700 Subject: [PATCH] target: restore last run state after profiling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that it’s possible to start profiling from either a running or a halted state, rather than unconditionally halting after profiling finishes, it makes more sense to restore the processor to whatever state (running or halted) it was in before profiling started.
