Subject: [PATCH 11/13] perf tools: Factor out sample__resolve_callchain()
Date: Wed, 15 Jan 2014 17:33:09 -0300 [thread overview]
Message-ID: <1389817991-8145-12-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1389817991-8145-1-git-send-email-acme@infradead.org>
From: Namhyung Kim <namhyung@kernel.org>
The report__resolve_callchain() can be shared with perf top code as it
doesn't really depend on the perf report code. Factor it out as
sample__resolve_callchain(). The same goes to the hist_entry__append_
callchain() too.
