Subject: [PATCH 5/5] perf record: Use unmapped IP for inline callchain cursors
Date: Fri,  5 Oct 2018 13:10:12 -0300	[thread overview]
Message-ID: <20181005161012.18475-6-acme@kernel.org> (raw)
In-Reply-To: <20181005161012.18475-1-acme@kernel.org>

From: Milian Wolff <milian.wolff@kdab.com>

Only use the mapped IP to find inline frames, but keep using the
unmapped IP for the callchain cursor. This ensures we properly show the
unmapped IP when displaying a frame we received via the
dso__parse_addr_inlines API for a module which does not contain
sufficient debug symbols to show the srcline.

This is another follow-up to commit 19610184693c ("perf script: Show
virtual addresses instead of offsets").
