Subject: [PATCH v5 6/7] perf annotate: Support jump instruction with target as second operand
Date: Fri, 19 Aug 2016 10:59:05 +0530 [thread overview]
Message-ID: <1471584546-11080-7-git-send-email-ravi.bangoria@linux.vnet.ibm.com> (raw)
In-Reply-To: <1471584546-11080-1-git-send-email-ravi.bangoria@linux.vnet.ibm.com>
Current perf is not able to parse jump instruction when second operand
contains target address. Arch like powerpc has such instructions. For
example, 'beq cr7,10173e60'.
