From 2d78f95bb639209254eb7252f9c48c520bd90d56 Mon Sep 17 00:00:00 2001 From: Andre Vieira Date: Thu, 16 May 2019 11:49:02 +0100 Subject: [PATCH] [PATCH 24/57][Arm][GAS] Add support for MVE instructions: vmlas, vmulh and vrmulh gas/ChangeLog: 2019-05-16 Andre Vieira * config/tc-arm.c (do_mve_vmlas): New encoding function. (do_mve_vmulh): Likewise. (insns): Add entries for MVE mnemonics. * testsuite/gas/arm/mve-vmlas-bad.d: New test. * testsuite/gas/arm/mve-vmlas-bad.l: New test. * testsuite/gas/arm/mve-vmlas-bad.s: New test. *
