Subject: [PATCH v4 3/4] powerpc/ppc-opcode: Add encoding macros for VSX vector paired instructions
Date: Thu, 8 Oct 2020 12:57:25 +0530 [thread overview]
Message-ID: <20201008072726.233086-4-ravi.bangoria@linux.ibm.com> (raw)
In-Reply-To: <20201008072726.233086-1-ravi.bangoria@linux.ibm.com>
From: Balamuruhan S <bala24@linux.ibm.com>
Add instruction encodings, DQ, D0, D1 immediate, XTP, XSP operands as
macros for new VSX vector paired instructions,
* Load VSX Vector Paired (lxvp)
* Load VSX Vector Paired Indexed (lxvpx)
* Prefixed Load VSX Vector Paired (plxvp)
* Store VSX Vector Paired (stxvp)
* Store VSX Vector Paired Indexed (stxvpx)
* Prefixed Store VSX Vector Paired (pstxvp)
