Subject: [PATCH 07/13] perf scripting python: Add perf_sample_insn()
Date: Sun, 30 May 2021 22:23:02 +0300 [thread overview]
Message-ID: <20210530192308.7382-8-adrian.hunter@intel.com> (raw)
In-Reply-To: <20210530192308.7382-1-adrian.hunter@intel.com>
Add perf_sample_insn() to the perf_trace_context module so that a script
can get the instruction bytes.
