2025-01-31x86: RMPUPDATE wants operands in different formJan Beulich3-51/+68
AMD are about to update their doc, to help clarify that what we currently do isn't quite right: In particular it is not %rax but %rcx which is affected by address size. In fact, that's a normal memory operand, just not expressed via ModR/M byte, but fixed to (%rcx) (or (%ecx) with 32-bit addressing). To support this in the assembler, generalize memory operand handling so far specific to XLAT (which isn't really a string insn, but requires its memory operand to be (%bx) / (%ebx) / (%rbx)). In the disassembler mimic handling after XLAT's, too.
2025-01-31x86-64: omit "default" segment prefixes from string insn disassemblyJan Beulich1-5/+8
Printing implicit %ds: and %es: prefixes is pretty meaningless in 64-bit mode. The SDM explicitly omits them for the 64-bit forms, and it obviously has them for the other ones only to cover non-64-bit modes (oddly enough the AMD PM has them present).

2025-01-27s390: Do not omit vector index register 0 in disassemblyJens Remus1-8/+5
Vector index registers are currently only used in the VRV instruction format. Unlike general purpose index registers an operand value of zero (e.g. %v0, 0, or omitted) does not imply a zero value: "For VRV format instructions, a vector element is used in the formation of the intermediate value. This vector element is an unsigned binary integer value that is added to the base address and 12-bit displacement to form a 64-bit intermediate sum. The vector element is designated by a vector register and an element index. A zero V field accesses the element in vector register zero and does not imply a zero value." [1] Therefore do not omit vector index register 0 in disassembly, that is disassemble D(VX,B) with VX=0 as D(VX,B) instead of D(B). Also do not disassemble index register 0 as "0", that is disassemble D(VX,B) with VX=0 as D(%v0,B) instead of D(0,B). Note that a base register 0 still still gets disassembled as "0", that is D(VX,B) with B=0 disassembles into D(VX,0).

2025-01-17aarch64: Fix sve2p1 gating and add missing instructionsAndrew Carlotti2-333/+457
Many FEAT_SVE2p1 instructions need to be enabled by either of two different features (one for streaming mode, and one for non-streaming mode). This patch adds correct gating conditions for these instructions. There were also a few sve2p1 instructions missing altogether, so add those as well. The testsuite is modified to check for all alternative enablement conditions. In many cases this is done by adding an alternative assembler commands to existing test files. For some SME/SME2 tests, only some of the instructions are enabled by +sve2p1, so these are copied into a separate test. For original SVE2p1 tests, the non-SME2p1 instructions have been moved to a separate test file. There are also new tests for the newly added instructions. These include a couple of fixme comments relating to bad error reporting, which should be investigated later.

2025-01-17x86: Ignore rounding for vcvt[,u]si2sd under r32 and vcvt[,u]dq2pd instead ↵Haochen Jiang2-4/+3

2025-01-14x86: Remove "NE" in mnemonics for convert insns related to AI data typesHaochen Jiang4-2133/+2133
NE is quite ambiguous and misleading in mnemonics since it should be Rounding to Nearest Even, but could be mis-interpretated to No Exception. Under its correct meaning, which means rounding, it should only be used in down-convert, since up-convert is always exact for normal values It could be difficult to judge which kind of convert it is if we have the convert between same bit float types. For all AI data types including BF16 and FP8, the default rounding is Rounding to Nearest Even. So removing them in mnemonics would reduce burden for programmers to consider whether it should be added or not in mnemonics and stop the ambiguous meaning on "NE" itself. If the convert itself is using a rounding mode other than RNE, it would be explicitly added in mnemonics (e.g., Long used "T" and "BIAS" introduced in AVX10.2). gas/ChangeLog: * testsuite/gas/i386/avx10_2-256-cvt-intel.d: Refine testcases according to mnemonics change. * testsuite/gas/i386/avx10_2-256-cvt.d: Ditto. * testsuite/gas/i386/avx10_2-256-cvt.s: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt-intel.d: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt.d: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt.s: Ditto. * testsuite/gas/i386/avx10_2-512-cvt-intel.d: Ditto. * testsuite/gas/i386/avx10_2-512-cvt.d: Ditto. * testsuite/gas/i386/avx10_2-512-cvt.s: Ditto. * testsuite/gas/i386/avx10_2-512-satcvt-intel.d: Ditto. * testsuite/gas/i386/avx10_2-512-satcvt.d: Ditto. * testsuite/gas/i386/avx10_2-512-satcvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-cvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-cvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-cvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-cvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-cvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-cvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt.s: Ditto. opcodes/ChangeLog: * i386-dis-evex-prefix.h: Remove ne in mnemonics for convert insns. * i386-opc.tbl: Ditto. * i386-mnem.h: Regenerated. * i386-tbl.h: Ditto.

2025-01-14x86: Remove "P" and "NE" in mnemonics for BF16 arithmetic insnsHaochen Jiang4-2238/+2238
Since the bf16 is an AI data types, it will be implicitly packed. Thus, "P" (for packed) is omitted in mnemonics from its introduction. AVX10.2 BF16 arithmetic insns are introduced with "P" in mnemonics with packed. This patch will remove them for consistency. NE is quite ambiguous and misleading in mnemonics since it should be Rounding to Nearest Even, but could be mis-interpretated to No Exception. While AI data types like BF16 and FP8 are using Rounding to Nearest Even as default rounding modes. There is no need to use the ambiguous mnemonics in AVX10.2 insns. This patch will also remove them.

2025-01-14Support Intel AMX-MOVRSHu, Lin111-2622/+2830
This patch will support AMX-MOVRS feature. Unlike all the other AMX insns in vector space where we pass vex_len_table before vex_w_table, we first pass vex_w_table for tileloaddrs[,t1] to align with the order in EVEX space. The reason why we first pass vex_w_table in EVEX space is due to AMX-AVX512, where tcvtrowd2ps and tilemovrow with r32 shares the same opcode with tileloaddrs[,t1]. All of them have evex.w = 0 but with different evex.length. Re-doing that shortly is not ideal. APX_F extension is also implemented in this patch. The encoding will be: - EVEX.128.NP/66.MAP5.W0 F8/F9 !(11):rrr:100 for T2RPNTLVW[Z0,Z1]RS[,T1] with NF=0. - EVEX.128.F2/66.0F38.W0 4A !(11):rrr:100 FOR TILELOADDRS[,T1] with NF=0. For APX_F extension, we could not use APX_F(AMX_TRANSPOSE&AMX_MOVRS) since the transformation could not be done. Instead, we will use AMX_TRANSPOSE & APX_F(AMX_MOVRS).

2025-01-14Support Intel MOVRSHu, Lin110-2649/+2792
This patch focus on supporting MOVRS ISA. We could take this full ISA as four part: PREFETCHRST2, MOVRS, MOVRS APX_F extension and MOVRS AVX10.2 extension. The APX_F extension for MOVRS will be: - EVEX.LLZ.NP.MAP4.WIG 8A !(11):rrr:bbb for r8/m8 with NF=0 and ND=0 - EVEX.LLZ.NP/66.MAP4.SCALABLE 8B !(11):rrr:bbb for rv/mv with NF=0 and ND=0 We did not merge the table together for APX_F since there is an explicit x64 for movrs insn.

When using MVexSIBMEM, OP_M will help check modrm. Thus, no need to pass mod_table. Since we have OP_M do the work, from now on, mod_table[] should not gain any new entries, unless both slots of them are populated, e.g., different modrm leading to different insns could not be combined (Bad_Opcode is not the case since OP_M could handle that). opcodes/ChangeLog: * i386-dis.c: Remove mod_table pass for MVexSIBMEM.
2025-01-10aarch64: Add support for FEAT_SME_B16B16 feature.Srinath Parvathaneni2-311/+535
This patch adds support for SME ZA-targeting non-widening BFloat16 instructions, under tick FEAT_SME_B16B16 and command line flag "+sme-b16b16". FEAT_SME_B16B16 implements FEAT_SME2 and FEAT_SVE_B16B16, in accordance with that "+sme-b16b16" enables "+sme2" and "+sve-b16b16". Also the test files related to FEAT_SME_B16B16 are prefixed with sme-b16b16*. eg: sme-b16b16-1.s, sme-b16b16-1.d.

As of commit e43d8768d909 ("RISC-V: Fix disassemble fetch fail return value.") partial instructions are no longer displayed by objdump. While that commit fixed the behavior of print_insn_riscv() returning the arbitrary status value upon failure, it caused the behavior of dumping instructions to change. Allow partial instructions to be displayed once again and only return -1 if no part of the instruction was able to be displayed.

2024-12-24arc: add_to_decodelistAlan Modra1-147/+124
Given objdump -Mcpu=archs -D or similar, add_to_decodelist adds three entries to decodelist for each instruction disassembled. That can waste a lot of cpu when the list grows large. What's more, decodelist is static and nothing clears the list. So the list persists from one file to the next if objdump is disassembling multiple files in one invocation. Wrong disassembly might result. To fix this problem, I've moved decodelist to the arc private_data and made it an array. I believe that init_disassemble_data will be called, clearing private_data, for each file disassembled. That's certainly true for objdump, and if I can see my way around gdb constructors, it's also true for gdb. I don't think there is a possibility of info.disassembler_options changing unless there is first a call to init_disassebled_data.

2024-12-18Support Intel SM4 AVX10.2 extensionHaochen Jiang6-9281/+9309
In this patch, we will support SM4 AVX10.2 extension part. It is a promotion from VEX encoding to EVEX encoding. The EVEX encoding is based on AVX10.2, which is the same as the upcoming MOVRS ISA. Thus, we decide to pull AVX10.2 out to CPU_COMMON_FLAGS. While I have also tried to merge the table like AVX/AVX512, I choose to just templatize the table. I am okay to go either way, but slightly prefer the templatizing one since probably SM4 would be the only ISA with AVX10.2 needs such VEX to EVEX extension (MOVRS does not need that). Also, it is a tendancy that we will directly provide EVEX encodings and no VEX encodings for vector instructions since AVX10. This will make the adding in gas/config/tc-i386.c not that worthy. gas/ChangeLog: * NEWS: Support Intel SM4 EVEX instructions. * config/tc-i386.c (_is_cpu): Handle AVX10.2. * testsuite/gas/i386/i386.exp: Run SM4 tests. * testsuite/gas/i386/x86-64.exp: Ditto. * testsuite/gas/i386/avx10_2-256-sm4-intel.d: Add SM4 tests. * testsuite/gas/i386/avx10_2-256-sm4.d: Ditto. * testsuite/gas/i386/avx10_2-256-sm4.s: Ditto. * testsuite/gas/i386/avx10_2-512-sm4-intel.d: Ditto. * testsuite/gas/i386/avx10_2-512-sm4.d: Ditto. * testsuite/gas/i386/avx10_2-512-sm4.s: Ditto. * testsuite/gas/i386/avx10_2-sm4-inval.l: Ditto. * testsuite/gas/i386/avx10_2-sm4-inval.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-sm4-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-sm4.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-sm4.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-sm4-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-sm4.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-sm4.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-sm4-inval.l: Ditto. * testsuite/gas/i386/x86-64-avx10_2-sm4-inval.s: Ditto. opcodes/ChangeLog: * i386-dis-evex.h: Add evex table entry for SM4. * i386-dis.h: Ditto. * i386-opc.h: (i386_cpu): Move AVX10.2 to CPU_FLAGS_COMMON. * i386-opc.tbl: Add SM4 EVEX instructions. * i386-init.h: Regenerated. * i386-tbl.h: Ditto.

.cfi directives only support the use of register numbers and not register names or aliases. This commit adds support for 4 formats, for example: .cfi_offset r1, 8 .cfi_offset ra, 8 .cfi_offset $r1,8 .cfi_offset $ra,8 The above .cfi directives are equivalent and all represent dwarf register number 1. Display register aliases as specified in the psABI during disassembly.
2024-12-05Support Intel AVX10.2 satcvt instructionsHu, Lin17-658/+1176
In this patch, we will support AVX10.2 satcvt instructions. All of them are new instruction forms. In current documentation, it is still VCVTTNEBF162I[,U]BS, but it will change to VCVTTBF162I[,U]BS eventually. In table part, we used temporary <sign> iterator to reduce redundancy. It definitely could be done for legacy cvt insns, but it is out of this patch's scope. gas/ChangeLog: * testsuite/gas/i386/i386.exp: Add AVX10.2 tests. * testsuite/gas/i386/x86-64.exp: Ditto. * testsuite/gas/i386/avx10_2-512-satcvt-intel.d: New test. * testsuite/gas/i386/avx10_2-512-satcvt.d: Ditto. * testsuite/gas/i386/avx10_2-512-satcvt.s: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt-intel.d: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt.d: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt.s: Ditto. opcodes/ChangeLog: * i386-dis-evex-prefix.h: Add PREFIX_EVEX_MAP5_68, PREFIX_EVEX_MAP5_69, PREFIX_EVEX_MAP5_6A, PREFIX_EVEX_MAP5_6B, PREFIX_EVEX_MAP5_6C, PREFIX_EVEX_MAP5_6D. * i386-dis-evex-w.h: Add EVEX_W_MAP5_6C_P_0, EVEX_W_MAP5_6C_P_2, EVEX_W_MAP5_6D_P_0, EVEX_W_MAP5_6D_P_2. * i386-dis-evex.h (prefix_table): Add PREFIX_EVEX_MAP5_68, * PREFIX_EVEX_MAP5_69, PREFIX_EVEX_MAP5_6A, PREFIX_EVEX_MAP5_6B. * i386-dis.c: (PREFIX_EVEX_MAP5_68): New.

2024-12-05x86: Eliminate unnecessary {evex} prefixesH.J. Lu4-11/+29
For several instructions including vps{l,r}l{d,q,w,dq} and vpsra{d,w}, their VEX part do not have the following version: vpsrlw $0x1f,(%r15,%rcx,4),%xmm0 Thus, {evex} prefix should not be inserted when their second operand is memory, while we still need them for register as second operand. Add a new macro %ME to solve this problem. For vpsraq, there is no VEX version, so the {evex} prefix should always be eliminated. gas/ChangeLog: PR binutils/32403 * testsuite/gas/i386/i386.exp: Run new test. * testsuite/gas/i386/x86-64.exp: Ditto. * testsuite/gas/i386/evex-only.d: New test. * testsuite/gas/i386/evex-only.s: Ditto. * testsuite/gas/i386/x86-64-evex-only.d: Ditto. * testsuite/gas/i386/x86-64-evex-only.s: Ditto. opcodes/ChangeLog: PR binutils/32403 * i386-dis-evex-reg.h: Use %ME instead of %XE for vps{l,r}l{w,dq} and vpsraw.
