Subject: [PATCH 2/2] perf tools: Hook up MIPS unwind and dwarf-regs in the Makefile
Date: Fri, 17 May 2013 12:00:38 -0700 [thread overview]
Message-ID: <1368817238-11548-3-git-send-email-ddaney.cavm@gmail.com> (raw)
In-Reply-To: <1368817238-11548-1-git-send-email-ddaney.cavm@gmail.com>
From: David Daney <david.daney@cavium.com>
Define a new symbol (ARCH_SUPPORTS_LIBUNWIND) in config/Makefile.
Use this from x86 and MIPS to gate testing of libunwind.
