2024-01-05RISC-V: T-HEAD: Fix wrong instruction encoding for th.vsetvliJin Ma1-0/+11
Since the particularity of "th.vsetvli" was not taken into account in the initial support patches for XTheadVector, the program operation failed due to instruction coding errors. According to T-Head SPEC ([1]), the "vsetvl" in the XTheadVector extension consists of SEW, LMUL and EDIV, which is quite different from the "V" extension. Therefore, we cannot simply reuse the processing of vsetvl in V extension. We have set up tens of thousands of test cases to ensure that no further encoding issues are there, and and execute all compiled test files on real HW and make sure they don't trigger SIGILL.

2023-12-01RISC-V: Zv*: Add support for Zvkb ISA extensionChristoph Müllner1-0/+1
Back then when the support for the RISC-V vector crypto extensions was merged, the specification was frozen, but not ratified. A frozen specification is allowed to change within tight bounds before ratification and this has happend with the vector crypto extensions. The following changes were applied: * A new extension Zvkb was defined, which is a strict subset of Zvbb. * Zvkn and Zvks include now Zvkb instead of Zvbb. This patch implements these changes between the frozen and the ratified specification. Note, that this technically an incompatible change of Zvkn and Zvks, but I am not aware of any project that depends on the currently implemented behaviour of Zvkn and Zvks. So this patch should be fine. Reported-By: Jerry Shih <jerry.shih@sifive.com> Reported-By: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu>

This patch adds the sub-extension "XTheadZvamo" for the "XTheadVector" extension, and it provides AMO instructions for T-Head VECTOR vendor extension.

2023-11-23RISC-V: Add T-Head VECTOR vendor extension.Jin Ma1-0/+1
T-Head has a range of vendor-specific instructions ([2]). Therefore it makes sense to group them into smaller chunks in form of vendor extensions. This patch adds the "XTheadVector" extension, a collection of T-Head-specific vector instructions. The 'th' prefix and the "XTheadVector" extension are documented in a PR for the RISC-V toolchain conventions ([1]). Here are some things that need to be explained: The "XTheadVector" extension is not a custom-extension, but a non-standard non-conforming extension. The encoding space of the "TheadVector" instructions overlaps with those of the 'V' extension. This encoding space conflict is not on purpose, but the result of issues in the past that have been resolved since. Therefore, the "XTheadVector" extension and the 'V' extension are in conflict.

Within the groups L{B,BU,H,HU,W,WU,D}, S{B,H,W,D}, FL{H,W,D,Q}, and FS{H,W,D,Q} the sole difference between the handling is the insn mnemonic passed to the common handling functions. The intended mnemonic, however, can easily be retrieved. Furthermore leverags that Sx and FSx are then handled identically, too, and hence their cases can also be folded.

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). This commit makes "fli.h" also available when both 'Zfa' and 'Zvfh' extensions are implemented. bfd/ChangeLog: * elfxx-riscv.c (riscv_multi_subset_supports): Add new instruction class handling.

This commit adds 'Zihintntl' extension and its hint instructions. This is based on: <https://github.com/riscv/riscv-isa-manual/commit/0dc91f505e6da7791d5a733c553e6e2506ddcab5>, the first ISA Manual noting that the 'Zihintntl' extension is ratified.

2023-08-15RISC-V: remove indirection from register tablesJan Beulich1-7/+9
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.

Everything that strtof() can parse is accepted and the '%a' printf specifier is used to output hex floating-point literals in the disassembly.

2023-04-26 RISC-V: Support XVentanaCondOps extensionPhilipp Tomsich1-0/+1
Ventana Micro has published the specification for their XVentanaCondOps ("conditional ops") extension at https://github.com/ventanamicro/ventana-custom-extensions/releases/download/v1.0.0/ventana-custom-extensions-v1.0.0.pdf which contains two new instructions - vt.maskc - vt.maskcn that can be used in constructing branchless sequences for various conditional-arithmetic, conditional-logical, and conditional-select operations. To support such vendor-defined instructions in the mainline binutils, this change also adds a riscv_supported_vendor_x_ext secondary dispatch table (but also keeps the behaviour of allowing any unknow X-extension to be specified in addition to the known ones from this table). As discussed, this change already includes the planned/agreed future requirements for X-extensions (which are likely to be captured in the riscv-toolchain-conventions repository): - a public specification document is available (see above) and is referenced from the gas-documentation - the naming follows chapter 27 of the RISC-V ISA specification - instructions are prefixed by a vendor-prefix (vt for Ventana) to ensure that they neither conflict with future standard extensions nor clash with other vendors bfd/ChangeLog: * elfxx-riscv.c (riscv_get_default_ext_version): Add riscv_supported_vendor_x_ext. (riscv_multi_subset_supports): Recognize INSN_CLASS_XVENTANACONDOPS. gas/ChangeLog: * doc/c-riscv.texi: Add section to list custom extensions and their documentation URLs. * testsuite/gas/riscv/x-ventana-condops.d: New test. * testsuite/gas/riscv/x-ventana-condops.s: New test. include/ChangeLog: * opcode/riscv-opc.h Add vt.maskc and vt.maskcn. * opcode/riscv.h (enum riscv_insn_class): Add INSN_CLASS_XVENTANACONDOPS. opcodes/ChangeLog: * riscv-opc.c: Add vt.maskc and vt.maskcn.

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.
2022-11-17RISC-V: Add T-Head Int vendor extensionChristoph Müllner1-0/+1
This patch adds the XTheadInt extension, which provides interrupt stack management instructions. The XTheadFmv extension is documented in the RISC-V toolchain contentions: https://github.com/riscv-non-isa/riscv-toolchain-conventions Co-developed-by: Lifang Xia <lifang_xia@linux.alibaba.com> Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu>
2022-11-17RISC-V: Add T-Head Fmv vendor extensionChristoph Müllner1-0/+1
This patch adds the XTheadFmv extension, which allows to access the upper 32 bits of a double-precision floating-point register in RV32. The XTheadFmv extension is documented in the RISC-V toolchain contentions: https://github.com/riscv-non-isa/riscv-toolchain-conventions Co-developed-by: Lifang Xia <lifang_xia@linux.alibaba.com> Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu>
2022-10-14RISC-V: Move certain arrays to riscv-opc.cTsukasa OI1-11/+2
This is a part of small tidying (declare tables in riscv-opc.c). include/ChangeLog: * opcode/riscv.h (riscv_rm, riscv_pred_succ): Move declarations to opcodes/riscv-opc.c. New non-static definitions. opcodes/ChangeLog: * riscv-opc.c (riscv_rm, riscv_pred_succ): Move from include/opcode/riscv.h. Add description.
