2015-11-27[AArch64][PATCH 3/3] Add floating-point FP16 instructionsMatthew Wahab3-0/+328
ARMv8.2 adds 16-bit floating point operations as an optional extension to the ARMv8 FP support. This patch adds the new FP16 instructions, making them available when the architecture extension +fp+fp16 is specified. The instructions added are: - Comparisons and conditionals: FCMP, FCCMPE, FCMP, FCMPE and FCSEL. - Arithmetic: FABS, FNEG, FSQRT, FMUL, FDIV, FADD, FSUB, FMADD, FMSUB, FNMADD and FNMSUB. - Rounding: FRINTN, FRINTP, FRINTM, FRINTZ, FRINTA, FRINTX and FRINTI. - Conversions: SCVTF (fixed-point), SCVTF (integer), UCVTF (fixed-point) UCVTF (integer), FCVTZS (fixed-point), FCVTZS (integer), FCVTZU (fixed-point), FCVTZU (integer), FCVTNS, FCVTNU, FCVTAS, FCVTAU, FCVTPS, FCVTPU, FCVTMS and FCVTMU. - Scalar FMOV: immediate, general and register gas/testsuite/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/float-fp16.d: New. * gas/aarch64/float-fp16.s: New. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Regenerate. * aarch64-opc-2.c: Regenerate. * aarch64-tbl.h (QL_FIX2FP_H, QL_FP2FIX_H): New.

2015-11-27[AArch64] Add ARMv8.2 instructions BFC and REV64.Matthew Wahab3-0/+134
ARMv8.2 adds two new instructions: BFC as an alias for BFM and REV64 as an alias for REV. This patch set adds support for these to binutils, enabled when the -march=armv8.2-a is given. It depends on the support for an instruction being its preferred form which was added in an earlier patch. This patch adds the alias BFC <Rd>, #<imm>, #<width> as the preferred form for BFM when the source is a zero register and the conditions for using the BFI form are met (in other words, BFC is the preferred form for BFI <Rd>, <Rs>, #<imm>, #<width> when the <Rs> is a zero register). gas/testsuite/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/alias-2.d: New. * gas/aarch64/alias-2.s: New. include/opcode/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64.h (aarch64_op): Add OP_BFC. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-asm-2.c: Regenerate. * aarch64-asm.c (convert_bfc_to_bfm): New.

2015-11-27[AArch64] Add feature flags and command line for ARMv8.2 FP16 support.Matthew Wahab3-0/+10
ARMv8.2 adds optional support for 16-bit operations to the FP and Adv.SIMD instructions. This patch adds a feature macro for this support with a new command line option "+fp16" to enable/disable it. Although the command line option is added as an architecture extension, it only affects instructions available with when +fp or +simd is enabled. If +fp16 is specified then it will also enable +fp. There are currently no FP16 instructions implemented in binutils, this patch is to enable subsequent work on supporting the extension. gas/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * config/tc-aarch64.c (aarch64_features): Add "fp16". * doc/c-aarch64.texi (Architecture Extensions): Add "fp16". include/opcode/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64.h (AARCH64_FEATURE_F16): New.

Fix a test quality regression introduced with commit 351cdf24 [[MIPS] Implement O32 FPXX, FP64 and FP64A ABI extensions] where MIPS ABI flags match patterns have been added to negative-match tests covering ELF file header flags. Negative-match tests succeed whenever there is a failure in matching output produced and consequently the likelihood of a false success increases when patterns to match irrelevant output are added.

2015-11-19[AArch64] Reject invalid immediate operands to MSR PANMatthew Wahab4-0/+30
The support for accessing the ARMv8.1 PSTATE field PAN allows instructions of the form MSR PAN, #<imm> with <imm> any unsigned 4-bit integer. However, the architecture specification requires that the immediate is either 0 or 1. This patch implements the constraint on the immediate, generating an error if the immediate operand is invalid, and adds tests for the illegal forms. opcodes/ 2015-11-19 Matthew Wahab <matthew.wahab@arm.com> * aarch64-opc.c (operand_general_constraint_met_p): Check validity of MSR PAN immediate operand. gas/testsuite/ 2015-11-19 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/pan-illegal.d: New. * gas/aarch64/pan-illegal.l: New. * gas/aarch64/pan.s: Add tests for invalid immediates.

2015-11-12[AArch64] Add support for Cortex-A35James Greenhalgh3-0/+8
This patch adds support to the AArch64 back-end for the Cortex-A35 processor, as recently announced by ARM. The ARM Cortex-A35 provides full support for the ARMv8-A architecture, including the CRC extension, with optional Advanced-SIMD and Floating-Point support. We therefore set feature flags for this CPU to AARCH64_ARCH_V8 and AARCH64_FEATURE_CRC, in the same fashion as Cortex-A53 and Cortex-A57. Tested in a cross environment for AArch64 with no issues.
