2024-07-12aarch64: disable feature b16b16Matthieu Longo1-2/+2
Feature b16b16 is currently incomplete and requires re-work. Disable the command line option for b16b16, and mark the associated tests as XFAIL.
2024-06-28aarch64: Add support for Armv9.5-A architectureClaudio Bantaloukas1-1/+2
The new -march=armv9.5-a flag enables access to the mandatory cpa, lut and faminmax extensions. Existing test cases for features are extended to verify they work without additional flags.
2024-06-24aarch64: Add SME FP8 multiplication instructionsAndrew Carlotti1-0/+4
This includes: - FEAT_SME_F8F32 (+sme-f8f32) - FEAT_SME_F8F16 (+sme-f8f16) The FP16 addition/subtraction instructions originally added by FEAT_SME_F16F16 haven't been added to Binutils yet. They are also required to be enabled if FEAT_SME_F8F16 is present, so they are included in this patch.
2024-06-24aarch64: Add FP8 Neon and SVE multiplication instructionsAndrew Carlotti1-0/+12

2024-06-24gas, aarch64: Add SME2 lutv2 extensionsaurabh.jha@arm.com1-0/+2
Introduces instructions for the SME2 lutv2 extension for AArch64. They are documented in the following document: * ARM DDI0602 For both luti4 instructions, we introduced an operand called SME_Znx2_BIT_INDEX. We use the existing function parse_vector_reg_list for parsing but modified that function so that it can accept operands without qualifiers and rejects instructions that have operands with qualifiers but are not supposed to have operands with qualifiers. For disassembly, we modified print_register_list so that it could accept register lists without qualifiers. For one luti4 instruction, we introduced a SME_Zdnx4_STRIDED. It is similar to SME_Ztx4_STRIDED and we could use existing code for parsing, encoding, and disassembly. For movt instruction, we introduced an operand called SME_ZT0_INDEX2_12. This is a ZT0 register with a bit index encoded in [13:12]. It is similar to SME_ZT0_INDEX. We also introduced an iclass named sme_size_12_b so that we can encode size bits [13:12] correctly when only 'b' is allowed as qualifier.
2024-06-12aarch64: add Branch Record Buffer extension instructionsClaudio Bantaloukas1-0/+2
The FEAT_BRBE extension provides two aliases of sys: - brb iall (Invalidates all Branch records in the Branch Record Buffer) - brb inj (Injects the Branch Record held in BRBINFINJ_EL1, BRBSRCINJ_EL1, and BRBTGTINJ_EL1 into the Branch Record Buffer) This patch adds: - the feature option "brbe" that must be added for the aliases to be available - a new operand flag AARCH64_OPND_Rt_IN_SYS_ALIASES that warns in a comment when Rt is set to the non default value 0b11111 (it is constrained unpredictable whether the instruction is undefined or behaves as if the Rt field is set to 0b11111). - a new operand flag AARCH64_OPND_BRBOP that encodes and decodes Op2 values from bit 5 - support for the two brb aliases above See: - https://developer.arm.com/documentation/ddi0602/2024-03/Base-Instructions/BRB--Branch-Record-Buffer--an-alias-of-SYS-?lang=en - https://developer.arm.com/documentation/ddi0601/2024-03/AArch64-Instructions/BRB-INJ--Branch-Record-Injection-into-the-Branch-Record-Buffer?lang=en - https://developer.arm.com/documentation/ddi0601/2024-03/AArch64-Instructions/BRB-IALL--Invalidate-the-Branch-Record-Buffer?lang=en
2024-05-31gas, aarch64: Fixes in texi and tests following faminmax and lut changessaurabh.jha@arm.com1-8/+8
Making two cleanups that came out of the comments from my previous patches: 1. Fixing `c-aarch64.texi` file so that the AArch64 architecture extensions are ordered alphabetically. 2. Fixing faminmax test cases so that they follow the existing test conventions.
2024-05-28gas, aarch64: Add AdvSIMD lut extensionsaurabh.jha@arm.com1-0/+2
Introduces instructions for the Advanced SIMD lut extension for AArch64. They are documented in the following links: * luti2: https://developer.arm.com/documentation/ddi0602/2024-03/SIMD-FP-Instructions/LUTI2--Lookup-table-read-with-2-bit-indices-?lang=en * luti4: https://developer.arm.com/documentation/ddi0602/2024-03/SIMD-FP-Instructions/LUTI4--Lookup-table-read-with-4-bit-indices-?lang=en These instructions needed definition of some new operands. We will first discuss operands for the third operand of the instructions and then discuss a vector register list operand needed for the second operand. The third operands are vectors with bit indices and without type qualifiers. They are called Em_INDEX1_14, Em_INDEX2_13, and Em_INDEX3_12 and they have 1 bit, 2 bit, and 3 bit indices respectively. For these new operands, we defined new parsing case branch. The lsb and width of these operands are the same as many existing but the convention is to give different names to fields that serve different purpose so we introduced new fields in aarch64-opc.c and aarch64-opc.h for these new operands. For the second operand of these instructions, we introduced a new operand called LVn_LUT. This represents a vector register list with stride 1. We defined new inserter and extractor for this new operand and it is encoded in FLD_Rn. We are enforcing the number of registers in the reglist using opcode flag rather than operand flag as this is what other SIMD vector register list operands are doing. The disassembly also uses opcode flag to print the correct number of registers.

2024-01-09aarch64: Add +d128 architectural feature supportVictor Do Nascimento1-0/+2
Indicating the presence of the Armv9.4-a features concerning 128-bit Page Table Descriptors, 128-bit System Registers and Instructions, the "+d128" architectural extension flag is added to the list of possible -march options in Binutils, together with the necessary macro for encoding d128 instructions.
2024-01-05Arm64: drop .bss overrideJan Beulich1-5/+0
The comment looks bogus (perhaps simply stale, perhaps wrongly copied from Arm in the first place), and there are also no other precautions against subsections being used on ELF with .bss. It also doesn't look to be a good idea to override the custom handlers that ELF and COFF have (afaict doing so further broke .previous on ELF). As to the mapping state update - such also doesn't appear to be done for other section switching, so its original purpose was at best questionable as well.
2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.

2023-03-30aarch64: Add sme-i16i64 and sme-f64f64 aliasesRichard Sandiford1-4/+4
Most extension flags are named after the associated architectural FEAT_* flags, but sme-i64 and sme-f64 were exceptions. This patch adds sme-i16i64 and sme-f64f64 aliases, but keeps the old names too for compatibility.
2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

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.
2021-12-16aarch64: Add support for Armv9.1-A to Armv9.3-ARichard Sandiford1-1/+2
This patch adds AArch64 support for -march=armv9.[123]-a. The behaviour of the new options can be expressed using a combination of existing feature flags, so we don't need to eat into the vanishing number of spare AARCH64_FEATURE_* bits. Hoewver, it was more convenient to separate out the |s of feature flags so that Armv9.1-A could reuse the set for Armv8.6-A, and so on. include/ * opcode/aarch64.h (AARCH64_ARCH_V8_FEATURES): New macro, split out from...
