Subject: [PATCH 08/10] perf tools: Limit unwind support to x86 archs
Date: Thu, 14 Feb 2013 18:44:21 -0300	[thread overview]
Message-ID: <1360878263-12694-9-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1360878263-12694-1-git-send-email-acme@infradead.org>

From: Jiri Olsa <jolsa@redhat.com>

There's DWARF unwind support only for x86 archs, so limit the unwind.o
object to them only.

Without this building for other archs (e.g. cross compiling for ARM) is
broken.
