2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.
2021-12-02aarch64: Add support for +mopsRichard Sandiford1-0/+4
This patch adds support for FEAT_MOPS, an Armv8.8-A extension that provides memcpy and memset acceleration instructions. I took the perhaps controversial decision to generate the individual instruction forms using macros rather than list them out individually. This becomes useful with a follow-on patch to check that code follows the correct P/M/E sequence.

2020-10-28aarch64: Add DSB instruction Armv8.7-a variantPrzemyslaw Wirkus1-141/+146
This patch adds new variant (nXS) of DSB memory barrier instruction available in Armv8.7-a. New nXS variant has different encoding in comparison with pre Armv8.7-a DSB memory barrier variant thus new instruction and new operand was added. DSB memory nXS barrier variant specifies the limitation on the barrier operation. Allowed values are: DSB SYnXS|#28 DSB ISHnXS|#24 DSB NSHnXS|#20 DSB OSHnXS|#16 Please note that till now, for barriers, barrier operation was encoded in 4-bit unsigned immediate CRm field (in the range 0 to 15). For DSB memory nXS barrier variant, barrier operation is a 5-bit unsigned assembly instruction immediate, encoded in instruction in two bits CRm<3:2>: CRm<3:2> #imm 00 16 01 20 10 24 11 28 This patch extends current AArch64 barrier instructions with above mapping. Notable patch changes include: + New DSB memory barrier variant encoding for Armv8.7-a. + New operand BARRIER_DSB_NXS for above instruction in order to distinguish between existing and new DSB instruction flavour. + New set of DSB nXS barrier options. + New instruction inserter and extractor map between instruction immediate 5-bit value and 2-bit CRm field of the instruction itself (see FLD_CRm_dsb_nxs). + Regeneration of aarch64-[asm|dis|opc]-2.c files. + Test cases to cover new instruction assembling and disassembling. For more details regarding DSB memory barrier instruction and its Armv8.7-a flavour please refer to Arm A64 Instruction set documentation for Armv8-A architecture profile, see document pages 132-133 of [0].

2020-04-20[AArch64, Binutils] Add missing TSB instructionSudakshina Das1-102/+104
This patch implements the TSB instructions: https://developer.arm.com/docs/ddi0596/f/base-instructions-alphabetic-order/ tsb-csync-trace-synchronization-barrier Since TSB and PSB both use the same (and only) argument "CSYNC", this patch reuses it for TSB. However, the same argument would imply different value for CRm:Op2 which are anyway fixed values, so I have diverted the inserter/extracter function to dummy versions instead of the "hint" version. The operand checker part still uses the existing infratructure for AARCH64_OPND_BARRIER_PSB to make sure the operand is parsed correctly. gas/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * config/tc-aarch64.c (parse_barrier_psb): Update error messages to include TSB. * testsuite/gas/aarch64/system-2.d: Update -march and new tsb tests. * testsuite/gas/aarch64/system-2.s: Add new tsb tests. * testsuite/gas/aarch64/system.d: Update. opcodes/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * aarch64-asm.c (aarch64_ins_none): New. * aarch64-asm.h (ins_none): New declaration. * aarch64-dis.c (aarch64_ext_none): New. * aarch64-dis.h (ext_none): New declaration. * aarch64-opc.c (aarch64_print_operand): Update case for AARCH64_OPND_BARRIER_PSB. * aarch64-tbl.h (aarch64_opcode_table): Add tsb.

2020-01-27AArch64: Fix cfinv disassembly issuesTamar Christina1-87/+87
This fixes the preferred disassembly for cfinv. The Armv8.4-a instruction overlaps with the possible encoding space for msr. This because msr allows you to use unallocated encoding space using the general sA_B_cC_cD_E form. However when an encoding does become allocated then we need to ensure that it's used as the preferred disassembly. The problem with cfinv is that its mask has all bits sets because it has no arguments. This causes issues for the Alias resolver in gas as it uses the mask to build alias graph. In this case it can't do it since it thinks almost everything would alias with cfinv. So instead we can only fix this by moving cfinv before msr. gas/ChangeLog: PR 25403 * testsuite/gas/aarch64/armv8_4-a.d: Add cfinv. * testsuite/gas/aarch64/armv8_4-a.s: Likewise. opcodes/ChangeLog: PR 25403 * aarch64-tbl.h (struct aarch64_opcode): Re-order cfinv. * aarch64-asm-2.c: Regenerate * aarch64-dis-2.c: Likewise. * aarch64-opc-2.c: Likewise.

2018-10-09[PATCH, BINUTILS, AARCH64, 2/9] Add Data procoessing instructions for ARMv8.5-ASudakshina Das1-450/+450
This patch is part of the patch series to add support for ARMv8.5-A extensions. (https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order) This patch adds the data processing instructions that are new to ARMv8.5-A. 1) There are 2 instructions: xaflag, axflag, that are added to manipulate the states of the flag and are used to convert between the Arm representation and the fcmp representation. 2) The other instructions are rounding instructions which have 8 versions based on whether the floating-point number is a Single-Precision or Double-Precision number, whether the target integer is a 32-bit or 64-bit integer and whether the rounding mode is the ambient rounding mode or to zero. Each of these instruction is available in both Scalar and Vector forms. Since both 1) and 2) have separate identification mechanism and it is permissible that a ARMv8.4 compliant implementation may include any arbitrary subset of the ARMv8.5 features unless otherwise specified, new feature bits are added. *** include/ChangeLog *** 2018-10-09 Sudakshina Das <sudi.das@arm.com> * opcode/aarch64.h (AARCH64_FEATURE_FLAGMANIP): New.

2018-06-29Fix AArch64 encodings for by element instructions.Tamar Christina1-68/+69
Some instructions in Armv8-a place a limitation on FP16 registers that can be used as the register from which to select an element from. e.g. fmla restricts Rm to 4 bits when using an FP16 register. This restriction does not apply for all instructions, e.g. fcmla does not have this restriction as it gets an extra bit from the M field. Unfortunately, this restriction to S_H was added for all _Em operands before, meaning for a large number of instructions you couldn't use the full register file. This fixes the issue by introducing a new operand _Em16 which applies this restriction only when paired with S_H and leaves the _Em and the other qualifiers for _Em16 unbounded (i.e. using the full 5 bit range). Also the patch updates all instructions that should be affected by this. opcodes/ PR binutils/23192 * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Likewise. * aarch64-opc-2.c: Likewise. * aarch64-dis.c (aarch64_ext_reglane): Add AARCH64_OPND_Em16 constraint. * aarch64-opc.c (operand_general_constraint_met_p, aarch64_print_operand): Likewise. * aarch64-tbl.h (aarch64_opcode_table): Change Em to Em16 for smlal, smlal2, fmla, fmls, fmul, fmulx, sqrdmlah, sqrdlsh, fmlal, fmlsl, fmlal2, fmlsl2.

2018-06-22Correct negs aliasing on AArch64.Tamar Christina1-1/+1
This patch fixes a disassembly issue with the aliases to subs with a shifted register. The subs instruction with the zero register as destination is supposed to alias to cmp and when the first input register is the zero register the subs is supposed to be aliased to negs. This means that a subs with destination and first input registers the zero register is supposed to be a cmp. This is done by raising the priority of the cmp alias. opcodes/ * aarch64-tbl.h (aarch64_opcode_table): Fix alias flag for negs * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Likewise. gas/ * testsuite/gas/aarch64/addsub.s: Add negs to zero reg test. * testsuite/gas/aarch64/addsub.d: Likewise.

report why. This patch if the first patch in a series to add the ability to add constraints to system registers that an instruction must adhere to in order for the register to be usable with that instruction. These constraints can also be used to disambiguate between registers with the same encoding during disassembly. This patch adds a new flags entry in the sysreg structures and ensures it is filled in and read out during assembly/disassembly. It also adds the ability for the assemble and disassemble functions to be able to gracefully fail and re-use the existing error reporting infrastructure. The return type of these functions are changed to a boolean to denote success or failure and the error structure is passed around to them. This requires aarch64-gen changes so a lot of the changes here are just mechanical. gas/ PR binutils/21446 * config/tc-aarch64.c (parse_sys_reg): Return register flags.
