2016-09-21[AArch64][SVE 28/32] Add SVE FP immediate operandsRichard Sandiford1-0/+8
This patch adds support for the new SVE floating-point immediate operands. One operand uses the same 8-bit encoding as base AArch64, but in a different position. The others use a single bit to select between two values. One of the single-bit operands is a choice between 0 and 1, where 0 is not a valid 8-bit encoding. I think the cleanest way of handling these single-bit immediates is therefore to use the IEEE float encoding itself as the immediate value and select between the two possible values when encoding and decoding. As described in the covering note for the patch that added F_STRICT, we get better error messages by accepting unsuffixed vector registers and leaving the qualifier matching code to report an error. This means that we carry on parsing the other operands, and so can try to parse FP immediates for invalid instructions like: fcpy z0, #2.5 In this case there is no suffix to tell us whether the immediate should be treated as single or double precision. Again, we get better error messages by picking one (arbitrary) immediate size and reporting an error for the missing suffix later. include/ * opcode/aarch64.h (AARCH64_OPND_SVE_FPIMM8): New aarch64_opnd.

2016-09-21[AArch64][SVE 27/32] Add SVE integer immediate operandsRichard Sandiford1-0/+39
This patch adds the new SVE integer immediate operands. There are three kinds: - simple signed and unsigned ranges, but with new widths and positions. - 13-bit logical immediates. These have the same form as in base AArch64, but at a different bit position. In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical immediate <limm> is not allowed to be a valid DUP immediate, since DUP is preferred over DUPM for constants that both instructions can handle. - a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}". In some contexts the operand is signed and in others it's unsigned. As an extension, we allow shifted immediates to be written as a single integer, e.g. "#256" is equivalent to "#1, LSL #8".

2016-09-21[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALEDRichard Sandiford1-0/+2
Some SVE instructions count the number of elements in a given vector pattern and allow a scale factor of [1, 16] to be applied to the result. This scale factor is written ", MUL #n", where "MUL" is a new operator. E.g.: UQINCD X0, POW2, MUL #2 This patch adds support for this kind of operand. All existing operators were shifts of some kind, so there was a natural range of [0, 63] regardless of context. This was then narrowered further by later checks (e.g. to [0, 31] when used for 32-bit values). In contrast, MUL doesn't really have a natural context-independent range. Rather than pick one arbitrarily, it seemed better to make the "shift" amount a full 64-bit value and leave the range test to the usual operand-checking code. I've rearranged the fields of aarch64_opnd_info so that this doesn't increase the size of the structure (although I don't think its size is critical anyway). include/ * opcode/aarch64.h (AARCH64_OPND_SVE_PATTERN_SCALED): New aarch64_opnd.

2016-09-21[AArch64][SVE 23/32] Add SVE pattern and prfop operandsRichard Sandiford1-0/+4
The SVE instructions have two enumerated operands: one to select a vector pattern and another to select a prefetch operation. The latter is a cut-down version of the base AArch64 prefetch operation. Both types of operand can also be specified as raw enum values such as #31. Reserved values can only be specified this way. If it hadn't been for the pattern operand, I would have been tempted to use the existing parsing for prefetch operations and add extra checks for SVE. However, since the patterns needed new enum parsing code anyway, it seeemed cleaner to reuse it for the prefetches too. Because of the small number of enum values, I don't think we'd gain anything by using hash tables. include/ * opcode/aarch64.h (AARCH64_OPND_SVE_PATTERN): New aarch64_opnd.

2016-09-21[AArch64][SVE 20/32] Add support for tied operandsRichard Sandiford1-16/+16
SVE has some instructions in which the same register appears twice in the assembly string, once as an input and once as an output. This patch adds a general mechanism for that. The patch needs to add new information to the instruction entries. One option would have been to extend the flags field of the opcode to 64 bits (since we already rely on 64-bit integers being available on the host). However, the *_INSN macros mean that it's easy to add new information as top-level fields without affecting the existing table entries too much. Going for that option seemed to give slightly neater code. include/ * opcode/aarch64.h (aarch64_opcode): Add a tied_operand field.

2016-08-23[AArch64] Add V8_2_INSN macroRichard Sandiford1-2/+4
For consistency with the previous two patches, this one adds a macro for the two ARMv8.2 table entries. Both table entries need a non-null aarch64_op field. I haven't added macros for the RAS and STAT_PROFILE entries since there's only one of each.

2016-08-23[AArch64] Add OP parameter to aarch64-tbl.h macrosRichard Sandiford1-722/+722
Nick recently wrapped most of aarch64-tbl.h entries in macros like CORE_INSN. These new macros assumed that the aarch64_op "op" field of aarch64_opcode is 0 and that the new "verifier" field is NULL. However, there are a lot of CORE, SIMD and FP insns whose table entries need a nonzero aarch64_op field, so these entries continued to use a braced list instead of a macro. This makes the table entries less consistent and means that there are still quite a few braced entries that need to be updated when making further changes to the aarch64_opcode structure. I think the number of entries that need a nonzero aarch64_op field is high enough to justify having an explicit aarch64_op entry for all CORE, SIMD and FP entries. This patch adds one and updates all existing uses of the macros. A following patch makes more use of the macros. I've followed existing practice by using 0 instead of OP_NIL for empty aarch64_op fields. Empty fields are still the norm and you need to know what the fields are when reading the table anyway, so it was hard to justify an additional patch to replace all 0 op fields with OP_NIL. opcodes/ * aarch64-tbl.h (CORE_INSN, __FP_INSN, SIMD_INSN): Add OP parameter.

The patches in this series: - Add a feature macro for use by the encoding/decoding mechanism. - Adjust a utility function, used when disassembling, to support 16-bit floating point values. - Add the new scalar floating-point instructions. This patch adds the feature macro FP_F16 to the AArch64 encoding/decoding mechanism, enabling it when both +fp and +fp16 are selected. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-tbl.h (aarch64_feature_fp_f16): New. (FP_F16): New. Change-Id: Ie370e43e3d77a7d54b4416b4be901b363a37f3d5
2015-11-27[AArch64] Add ARMv8.2 instruction alias REV64.Matthew Wahab1-1/+4
This patch adds the alias REV64 <Rd>, <Rs> as an alias for REV <Rd>, <Rs>. However, REV is still the preferred form for the instruction. gas/testsuite/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/alias-2.d: Add tests for REV. * gas/aarch64/alias-2.s: Likewise. 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 (aarchr64_opcode_table): Update "rev", add "rev64".

2015-11-27[AArch64] Add ARMv8.2 instructions BFC and REV64.Matthew Wahab1-0/+12
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.
