From c2c4ff8d52a2cd3263a547b0384692498714aa1b Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Fri, 18 Nov 2016 10:02:16 +0000 Subject: [AArch64] Add ARMv8.3 FCMLA and FCADD instructions Add support for FCMLA and FCADD complex arithmetic SIMD instructions. FCMLA has an indexed element variant where the index range has to be treated specially because a complex number takes two elements and the indexed vector size depends on the other operands. These complex number SIMD instructions are part of ARMv8.3 https://community.arm.com/groups/processors/blog/2016/10/27/armv8-a-architecture-2016-additions include/ 2016-11-18 Szabolcs Nagy * opcode/aarch64.h (enum aarch64_opnd): Add AARCH64_OPND_IMM_ROT1, AARCH64_OPND_IMM_ROT2, AARCH64_OPND_IMM_ROT3.
