Subject: [PATCH v2 5/6] powerpc/ppc-opcode: reuse raw instruction macros to stringify
Date: Wed, 24 Jun 2020 17:00:37 +0530	[thread overview]
Message-ID: <20200624113038.908074-6-bala24@linux.ibm.com> (raw)
In-Reply-To: <20200624113038.908074-1-bala24@linux.ibm.com>

Wrap existing stringify macros to reuse raw instruction encoding macros that
are newly added.
