2017-12-19Correct disassembly of dot product instructions.Tamar Christina1-2/+8
Dot products deviate from the normal disassembly rules for lane indexed instruction. Their canonical representation is in the form of: v0.2s, v0.8b, v0.4b[0] instead of v0.2s, v0.8b, v0.b[0] to try to denote that these instructions select 4x 1 byte elements instead of a single 1 byte element. Previously we were disassembling them following the normal rules, this patch corrects the disassembly. gas/ PR gas/22559 * config/tc-aarch64.c (vectype_to_qualifier): Support AARCH64_OPND_QLF_S_4B. * gas/testsuite/gas/aarch64/dotproduct.d: Update disassembly. include/ PR gas/22559 * aarch64.h (aarch64_opnd_qualifier): Add AARCH64_OPND_QLF_S_4B. opcodes/ PR gas/22559 * aarch64-asm.c (aarch64_ins_reglane): Change AARCH64_OPND_QLF_S_B to AARCH64_OPND_QLF_S_4B * aarch64-dis.c (aarch64_ext_reglane): Change AARCH64_OPND_QLF_S_B to AARCH64_OPND_QLF_S_4B * aarch64-opc.c (aarch64_opnd_qualifiers): Add 4b variant. * aarch64-tbl.h (QL_V2DOT): Change S_B to S_4B.
2017-12-19Add support for V_4B so we can properly reject it.Tamar Christina1-3/+3
Previously parse_vector_type_for_operand was changed to allow the use of 4b register size for indexed lane instructions. However this had the unintended side effect of also allowing 4b for normal vector registers. Because this support was only partial the rest of the tool silently treated 4b as 8b and continued. This patch adds full support for 4b so it can be properly distinguished from 8b and the correct errors are generated. With this patch you still can't encode any instruction which actually requires v<num>.4b but such instructions don't exist so to prevent needing a workaround in get_vreg_qualifier_from_value this was just omitted. gas/ PR gas/22529 * config/tc-aarch64.c (vectype_to_qualifier): Support AARCH64_OPND_QLF_V_4B. * gas/testsuite/gas/aarch64/pr22529.s: New. * gas/testsuite/gas/aarch64/pr22529.d: New. * gas/testsuite/gas/aarch64/pr22529.l: New. include/ PR gas/22529 * opcode/aarch64.h (aarch64_opnd_qualifier): Add AARCH64_OPND_QLF_V_4B. opcodes/ PR gas/22529 * aarch64-opc.c (aarch64_opnd_qualifiers): Add 4b variant.

2017-11-08Split the AArch64 Crypto instructions for AES and SHA1+2 into their own ↵Nick Clifton1-1/+7
options (+aes and +sha2). The new options are: +aes: Enables the AES instructions of Armv8-a, enabled by default with +crypto. +sha2: Enables the SHA1 and SHA2 instructions of Armv8-a, enabled by default with +crypto. These options have been turned on by default when +crypto is used, as such no breakage is expected. The reason for the split is because with the introduction of Armv8.4-a the implementation of AES has explicitly been made independent of the implementation of the other crypto extensions. Backporting the split does not break any of the previous requirements and so is safe to do. gas * config/tc-aarch64.c (aarch64_features): Include AES and SHA2 in CRYPTO.

2017-08-15[Patch AArch64] Turn lr, fp, ip0 and ip1 into proper aliasesRamana Radhakrishnan1-5/+6
We got a report from the linux-arm-kernel folks about getting spurious warnings when building the kernel with binutils 2.29. See https://www.spinics.net/lists/arm-kernel/msg599929.html which boils down to this testcase. $> cat /tmp/tst.s lr .req x30 /tmp/tst.s: Assembler messages: /tmp/tst.s:1: Warning: ignoring attempt to redefine built-in register 'lr' Instead let's treat this as a proper alias at startup time thus avoiding the problem and treating these as proper aliases rather than new registers. This means that attempts to redefine the alias with the same "name" will provoke no warning and attempts to redefine the alias to something else will provoke the above mentioned warning. Tested make check-gas and no regressions. Ok to apply to trunk (and backport to 2.29 branch)? Regards Ramana

2016-09-21[AArch64][SVE 28/32] Add SVE FP immediate operandsRichard Sandiford1-3/+38
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/+27
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". We also use the shiftless form as the preferred disassembly, except for the special case of "#0, LSL #8" (a redundant encoding of 0). include/ * opcode/aarch64.h (AARCH64_OPND_SIMM5): New aarch64_opnd.

2016-09-21[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALEDRichard Sandiford1-1/+41
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/+64
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 Sandiford1-0/+5
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. (AARCH64_OPDE_UNTIED_OPERAND): New aarch64_operand_error_kind. opcodes/ * aarch64-tbl.h (CORE_INSN, __FP_INSN, SIMD_INSN, CRYP_INSN) (_CRC_INSN, _LSE_INSN, _LOR_INSN, RDMA_INSN, FP16_INSN, SF16_INSN) (V8_2_INSN, aarch64_opcode_table): Initialize tied_operand field. * aarch64-opc.c (aarch64_match_operands_constraint): Check for tied operands. gas/ * config/tc-aarch64.c (output_operand_error_record): Handle AARCH64_OPDE_UNTIED_OPERAND.
2016-09-21[AArch64][SVE 13/32] Add an F_STRICT flagRichard Sandiford1-4/+1
SVE predicate operands can appear in three forms: 1. unsuffixed: "Pn" 2. with a predication type: "Pn/[ZM]" 3. with a size suffix: "Pn.[BHSD]" No variation is allowed: unsuffixed operands cannot have a (redundant) suffix, and the suffixes can never be dropped. Unsuffixed Pn are used in LDR and STR, but they are also used for Pg operands in cases where the result is scalar and where there is therefore no choice to be made between "merging" and "zeroing". This means that some Pg operands have suffixes and others don't. It would be possible to use context-sensitive parsing to handle this difference. The tc-aarch64.c code would then raise an error if the wrong kind of suffix is used for a particular instruction. However, we get much more user-friendly error messages if we parse all three forms for all SVE instructions and record the suffix as a qualifier. The normal qualifier matching code can then report cases where the wrong kind of suffix is used. This is a slight extension of existing usage, which really only checks for the wrong choice of suffix within a particular kind of suffix. The only catch is a that a "NIL" entry in the qualifier list specifically means "no suffix should be present" (case 1 above). NIL isn't a wildcard here. It also means that an instruction that requires all-NIL qualifiers can fail to match (because a suffix was supplied when it shouldn't have been); this requires a slight change to find_best_match. This patch adds an F_STRICT flag to select this behaviour. The flag will be set for all SVE instructions. The behaviour for other instructions doesn't change. include/ * opcode/aarch64.h (F_STRICT): New flag. opcodes/ * aarch64-opc.c (match_operands_qualifier): Handle F_STRICT. gas/ * config/tc-aarch64.c (find_best_match): Simplify, allowing an instruction with all-NIL qualifiers to fail to match.
2016-09-21[AArch64][SVE 12/32] Remove boolean parameters from parse_address_mainRichard Sandiford1-24/+21
In the review of the original version of this series, Richard didn't like the use of boolean parameters to parse_address_main. I think we can just get rid of them and leave the callers to check the addressing modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this for relocation operators (i.e. it used parse_address_reloc and then rejected relocations). The callers are already set up to reject invalid register post-indexed addressing, so we can simply remove the accept_reg_post_index parameter without adding any more checks. This again creates a corner case where: .equ x2, 1 ldr w0, [x1], x2 was previously an acceptable way of writing "ldr w0, [x1], #1" but is now rejected. Removing the "reloc" parameter means that two cases need to check explicitly for relocation operators. ADDR_SIMM9_2 appers to be unused. I'll send a separate patch to remove it. This patch makes parse_address temporarily equivalent to parse_address_main, but later patches in the series will need to keep the distinction. gas/ * config/tc-aarch64.c (parse_address_main): Remove reloc and accept_reg_post_index parameters. Parse relocations and register post indexes unconditionally. (parse_address): Remove accept_reg_post_index parameter. Update call to parse_address_main. (parse_address_reloc): Delete. (parse_operands): Call parse_address instead of parse_address_main. Update existing callers of parse_address and make them check inst.reloc.type where appropriate. * testsuite/gas/aarch64/diagnostic.s: Add tests for relocations in ADDR_SIMPLE, SIMD_ADDR_SIMPLE, ADDR_SIMM7 and ADDR_SIMM9 addresses. Also test for invalid uses of post-index register addressing. * testsuite/gas/aarch64/diagnostic.l: Update accordingly.
