2025-06-24RISC-V: Support for unlabeled landing pad PLT generationKito Cheng1-0/+1
This patch adds support for generating unlabeled landing pad PLT entries for the RISC-V architecture. Unlabeled landing pad will place a LPAD instruction at the PLT entry and PLT header, also PLT header will have few changes due to the offset is different from the original one.

2025-03-18RISC-V: Add extension XTheadVdot for T-Head VECTOR vendor extension [1]Jin Ma1-0/+1
T-Head has a range of vendor-specific instructions. Therefore it makes sense to group them into smaller chunks in form of vendor extensions. This patch adds the additional extension "XTheadVdot" based on the "V" extension, and it provides four 8-bit multiply and add with 32-bit instructions for the "v" extension. The 'th' prefix and the "XTheadVector" extension are documented in a PR for the RISC-V toolchain conventions ([2]).

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>

2023-11-23RISC-V: Add sub-extension XTheadZvamo for T-Head VECTOR vendor extensionJin Ma1-0/+1
T-Head has a range of vendor-specific instructions. Therefore it makes sense to group them into smaller chunks in form of vendor extensions. This patch adds the sub-extension "XTheadZvamo" for the "XTheadVector" extension, and it provides AMO instructions for T-Head VECTOR vendor extension. The 'th' prefix and the "XTheadVector" extension are documented in a PR for the RISC-V toolchain conventions ([1]).

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.

2023-11-03RISC-V: reduce redundancy in load/store macro insn handlingJan Beulich1-19/+3
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.

2023-08-15RISC-V: Make "fli.h" available to 'Zvfh' + 'Zfa'Tsukasa OI1-0/+1
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 Beulich1-7/+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.
