2023-08-23kvx: O_pseudo_fixupAlan Modra3-23/+36
O_pseudo_fixup was defined as O_max+1, missing the fact that O_md1 through O_md32 enums are for use by target code. Worse, kvx-parse.c used 64 rather than O_pseudo_fixup. Fix this, and wrap some overlong lines. * config/tc-kvx.h (O_pseudo_fixup): Define. * config/tc-kvx.c (O_pseudo_fixup): Don't define here. (insert_operand): Delete bogus comment and cast. * config/kvx-parse.c (promote_token): Use O_pseudo_fixup rather than hardcoded value. Wrap overlong lines. (get_token_class): Likewise.

2023-08-23kvx: ubsan: integer overflowAlan Modra2-4/+4
This fixes a few places where ubsan complains about signed integer overflow when running the testsuite, and that clz(0) is undefined. When fixing the clz problem, I also noticed that we'd get complaints if pval is ever LLONG_MIN. Fix that by using unsigned arithmetic. * config/kvx-parse.c (get_token_class): Avoid signed overflow. Don't clz(0). * config/tc-kvx.c (PARALLEL_BIT): Avoid signed overflow.
2023-08-23kvx: asan: out-of-bounds readAlan Modra1-1/+2
kvx-parse.c:parse_with_restarts does if (!tok.insn[tok.begin]) tok.class_id = -3; then a little later printf_debug (1, "\nEntering rule: %d (Trying to match: (%s)[%d])\n", jump_target, TOKEN_NAME (CLASS_ID (tok)), CLASS_ID (tok)); This results in a buffer overrun in TOKEN_NAME. Fix that. * config/tc-kvx.h (TOKEN_NAME): Check for tok <= 0, not just -1.
2023-08-22aarch64: Improve naming conventions for A and R-profile architectureVictor Do Nascimento1-53/+53
Historically, flags and variables relating to architectural revisions for the A-profile architecture omitted the trailing `A' such that, for example, assembling for `-march=armv8.4-a' set the `AARCH64_ARCH_V8_4' flag in the assembler. This leads to some ambiguity, since Binutils also targets the R-profile Arm architecture. Therefore, it seems prudent to have everything associated with the A-profile cores end in `A' and likewise `R' for the R-profile. Referring back to the example above, the flag set for `-march=armv8.4-a' is better characterized if labeled `AARCH64_ARCH_V8_4A'. The only exception to the rule of appending `A' to variables is found in the handling of the `AARCH64_FEATURE_V8' macro, as it is the baseline from which ALL processors derive and should therefore be left unchanged. In reflecting the `ARM' architectural nomenclature choices, where we have `ARM_ARCH_V8A' and `ARM_ARCH_V8R', the choice is made to not have an underscore separating the numerical revision number and the A/R-profile indicator suffix. This has meant that renaming of R-profile related flags and variables was warranted, thus going from `.*_[vV]8_[rR]' to `.*_[vV]8[rR]'. Finally, this is more in line with conventions within GCC and adds consistency across the toolchain. gas/ChangeLog: * gas/config/tc-aarch64.c: (aarch64_cpus): Reference to arch feature macros updated.

2023-08-21bpf: correct neg and neg32 instruction encodingDavid Faust13-42/+8
The neg/neg32 BPF instructions always use BPF_SRC_K (=0) in their header source bit, despite operating on registers. If BPF_SRC_X (=1) is set, the instructions are rejected by the kernel. Because of this there are also no neg/neg32 instructions which operate on immediates, so remove them. bd434cc4d94ec3d2f9fc1e7c00c27b074f962bc1 was a similar fix in the old CGEN-based port, but was not carried forward in the new port. include/ * opcode/bpf.h (enum bpf_insn_id): Remove spurious entries BPF_INSN_NEGI and BPF_INSN_NEG32I. opcodes/ * bpf-opc.c (bpf_opcodes): Remove erroneous NEGI and NEG32I instructions. gas/ * doc/c-bpf.texi (BPF Instructions): Remove erroneous neg and neg32 instructions operating on immediates. * testsuite/gas/bpf/alu.s: Adapt accordingly. * testsuite/gas/bpf/alu.d: Likewise. * testsuite/gas/bpf/alu-be.d: Likewise * testsuite/gas/bpf/alu32.s: Likewise. * testsuite/gas/bpf/alu32.d: Likewise. * testsuite/gas/bpf/alu32-be.d: Likewise. * testsuite/gas/bpf/alu-pseudoc.s: Likewise. * testsuite/gas/bpf/alu-pseudoc.d: Likewise. * testsuite/gas/bpf/alu-be-pseudoc.d: Likewise. * testsuite/gas/bpf/alu32-pseudoc.s: Likewise. * testsuite/gas/bpf/alu32-pseudoc.d: Likewise. * testsuite/gas/bpf/alu32-be-pseudoc.d: Likewise.

The longest register name is 3 characters (plus a nul one), so using a 4- or 8-byte pointer to get at it is neither space nor time efficient. Embed the names right into the array. For PIE this also slightly reduces the number of base relocations in the final image.
2023-08-18gas: make S_IS_LOCAL() and S_IS_EXTERNAL() exclusive of one anotherJan Beulich1-5/+4
While they aren't opposites of each other, there also shouldn't be any symbol for which both return true; both may return false. Therefore use S_IS_EXTERNAL() in S_IS_LOCAL(), thus subsuming the sanity check which so far both did alike.

The elf32-kvx.c and elf64-kvx.c rules in the bfd makefile are different to the other similar generated files, and that reminded me that we need to have $srcdir in the generated #line reference back to the source for debugging, but don't want it for comments in bfd.pot (because then bfd.pot will likely reference Nick's source tree).

2023-08-17bpf: gas: consolidate handling of immediate overflowsJose E. Marchesi20-67/+96
This commit changes the BPF GAS port in order to handle immediate overflows the same way than the clang BPF assembler: - For an immediate field of N bits, any written number (positive or negative) whose two's complement encoding fit in N its is accepted. This means that -2 is the same than 0xffffffe. It is up to the instructions to decide how to interpret the encoded value. - Immediate fields in jump instructions are no longer relaxed. Relaxing to jump instructions with wider range is only performed when expressions are involved. - The manual is updated to document this, and testsuite adapted accordingly. Tested in x86_64-linux-gnu host, bpf-unknown-none target. gas/ChangeLog: 2023-08-17 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-bpf.c (check_immediate_overflow): New function.

2023-08-15RISC-V: Make T-Head testing pattern more genericTsukasa OI6-20/+20
On some T-Head vendor extensions, we test against the constant 18446744073709551615 (2**64-1) to detect invalid immediate errors on -1. However, it heavily depends on the fact that the value used to print immediate value is a 64-bit unsigned type and this constant is not (and should not be) important (we just want to know that -1 is not valid). This commit replaces all such occurrences of 18446744073709551615 with a more generic regular expression. gas/ChangeLog: * testsuite/gas/riscv/x-thead-ba-fail.l: Replace 18446744073709551615 with generic regular expression. * testsuite/gas/riscv/x-thead-bb-fail.l: Likewise. * testsuite/gas/riscv/x-thead-bs-fail.l: Likewise. * testsuite/gas/riscv/x-thead-fmemidx-fail.l: Likewise. * testsuite/gas/riscv/x-thead-memidx-fail.l: Likewise. * testsuite/gas/riscv/x-thead-mempair-fail.l: Likewise.

The documentation of the 'Zfa' extension states that "fli.h" is available "if the Zfh or Zvfh extension is implemented" (both the latest and the oldest editions are checked). This fact was not reflected in Binutils ('Zvfh' implies 'Zfhmin', not full 'Zfh' extension and "fli.h" required 'Zfh' and 'Zfa' extensions).

2023-08-15RISC-V: remove indirection from register tablesJan Beulich1-1/+1
The longest register name is 4 characters (plus a nul one), so using a 4- or 8-byte pointer to get at it is neither space nor time efficient. Embed the names right into the array. For PIE this also reduces the number of base relocations in the final image. To avoid old gcc, when generating 32-bit code, bogusly warning about bounds being exceeded in the code processing Cs/Cw, Ct/Cx, and CD, an adjustment to EXTRACT_BITS() is needed: This macro shouldn't supply a 64-bit value, and it also doesn't need to - all operand fields to date are far more narrow than 32 bits. This in turn allows dropping a number of casts elsewhere.

2023-08-11x86: pack CPU flags in opcode tableJan Beulich1-73/+116
The table constantly growing in two dimensions (number of table entries times number of ISA extension flags) doesn't scale very well. Use a more compact representation: Only identifiers which need to combine with other identifiers retain individual flag bits. All others are combined into an enum, with a new helper added to transform the table entries into the original i386_cpu_flags layout. This way the table in the final binary shrinks by almost a third (the generated source code shrinks by about half), and isn't likely to grow again in that dimension any time soon. While moving the 3DNow! fields, drop the stray inner 'a' from their names.

2023-07-30bpf: include, bfd, opcodes: add EF_BPF_CPUVER ELF header flagsJose E. Marchesi4-0/+18
This patch adds support for EF_BPF_CPUVER bits in the ELF machine-dependent header flags. These bits encode the BPF CPU version for which the object file has been compiled for. The BPF assembler is updated so it annotates the object files it generates with these bits. The BPF disassembler is updated so it honors EF_BPF_CPUVER to use the appropriate ISA version if the user didn't specify an explicit ISA version in the command line. Note that a value of zero in EF_BPF_CPUVER is interpreted by the disassembler as "use the later supported version" (the BPF CPU versions start with v1.)

2023-07-28bpf: gas: support relaxation of V4 jump instructionsJose E. Marchesi9-308/+858
The BPF jump-always instruction (JA), like all other jump instructions in the ISA, get a signed 16-bit displacement target argument denoted in number of 64-bit words minus one. This can sometimes be overflown. The BPF V4 ISA thus introduced support for a jump-always instruction (JAL) that gets a signed 32-bit displacement instead. This patch makes the BPF assembler to perform the following relaxations when the disp16 field gets overflown, unless the option -mno-relax is specified: JA disp16 -> JAL disp32 Jxx disp16 -> Jxx +1; JA +1; JAL disp32 Documentation and tests added.

2023-07-28MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targetsYunQiang Su4-8/+8
Make the n64 ABI the default for 64-bit Linux targets specified with `-gnuabi64' suffix included in the target triplet, for configurations such as the Debian mips64el and mips64r6el ports. Adjust testsuite configuration accordingly. There are the following regressions with the new target triplet: mips64-linux-gnuabi64 +FAIL: readelf -S bintest mips64-linux-gnuabi64 +FAIL: MIPS reloc estimation 1 mips64el-linux-gnuabi64 +FAIL: readelf -S bintest mips64el-linux-gnuabi64 +FAIL: MIPS reloc estimation 1 The `readelf' issue comes from a difference in section headers produced that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template does not match. While there has been a precedent it does not appear to me that there is a clear advantage from adding more and more variations to the template rather than forking the existing template into multiple ones for a more exact match. So this is best deferred to a separate discussion. The MIPS reloc estimation issue is an actual bug in `objdump', which discards a number of trailing entries from output here for n64 composed relocations: DYNAMIC RELOCATION RECORDS OFFSET TYPE VALUE 0000000000000000 R_MIPS_NONE *ABS* 0000000000000000 R_MIPS_NONE *ABS* and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not match even though ELF output produced is correct according to `readelf': Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries: Offset Info Type Sym.
