From b5b0f34c669a91b9d873221ea3d688cf7f495ab5 Mon Sep 17 00:00:00 2001 From: Matthew Wahab Date: Mon, 14 Dec 2015 17:40:03 +0000 Subject: [AArch64][PATCH 13/14] Support FP16 Adv.SIMD Shift By Immediate instructions. ARMv8.2 adds 16-bit floating point operations as an optional extension to the floating point and Adv.SIMD support. This patch extends instructions in the group Adv.SIMD Shift By Immediate to support FP16, making this support available when +simd+fp16 is enabled. The new instructions legal make some uses of the 4h vector type that had been invalid. This patch adjusts a test that checks for these uses. The extended instructions are: SCVTF, FCVTZS, UCVTF and FCVTZU. The general form for these instructions is ., ., # where T is 4h or 8h. gas/testsuite/ 2015-12-14 Matthew Wahab * gas/aarch64/advsimd-fp16.d: Update expected output. * gas/aarch64/advsimd-fp16.s: Add tests for Adv.SIMD across lanes instructions. * gas/aarch64/illegal.d: Update expected output. * gas/aarch64/illegal.s: Replace tests for illegal use of 'h' specifier. opcodes/ 2015-12-14 Matthew Wahab * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Regenerate. * aarch64-opc-2.c: Regenerate. * aarch64-tbl.h (QL_VSHIFT_H): New.
