[commit] simplify dummy frame sniffer
- From: Andrew Cagney <cagney at gnu dot org>

- Subject: [commit] simplify dummy frame sniffer
Hello,
This patch simplifies the dummy frame sniffer a little by always
checking the dummy frame stack for entries.
For the !DEPRECATED_USE_GENERIC_DUMMY_FRAMES case, since that stack is
empty, the search never succeeds and hence the sniff always fails
(retaining old behavior).
committed,
Andrew

* frame-unwind.c (frame_unwind_find_by_frame): Delete check for
generic dummy frames.
* dummy-frame.c: Update copyright.
(dummy_frame_sniffer): Delete check for generic dummy frames.
