2023-12-01RISC-V: Zv*: Add support for Zvkb ISA extensionChristoph Müllner1-2/+2
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>

2023-09-05RISC-V: Add 'Smcntrpmf' extension and its CSRsTsukasa OI1-4/+12
This commit adds now stable and approved 'Smcntrpmf' extension defined by the RISC-V Cycle and Instret Privilege Mode Filtering specification. Note that, because mcyclecfg and minstretcfg CSRs conflict with the privileged specification version 1.9.1, CSRs for this extension are only enabled on the privileged specification version 1.10 or later. By checking the base privileged specification, we no longer need to change the design of base CSR handling. This is based on the specification version v1.0_rc1 (Frozen): <https://github.com/riscv/riscv-smcntrpmf/commit/32b752c40d59c1b5e95de83399c1f54be6669163> bfd/ChangeLog: * elfxx-riscv.c (riscv_implicit_subsets): Add implication rule from the new 'Smcntrpmf' extension.

This extension adds the following instructions: - vandn.[vv,vx] - vbrev.v - vbrev8.v - vrev8.v - vclz.v - vctz.v - vcpop.v - vrol.[vv,vx] - vror.[vv,vx,vi] - vwsll.[vv,vx,vi] bfd/ChangeLog: * elfxx-riscv.c (riscv_multi_subset_supports): Add instruction class support for Zvbb.

2023-06-30RISC-V: Add support for the Zfa extensionChristoph Müllner1-0/+99
This patch adds support for the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of FP registers in case XLEN < FLEN * fleq/fltq (quiet comparison instructions) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) This patch is based on an earlier version from Tsukasa OI: https://sourceware.org/pipermail/binutils/2022-September/122939.html Most significant change to that commit is the switch from the rs1-field value to the actual floating-point value in the last operand of the fli* instructions. Everything that strtof() can parse is accepted and the '%a' printf specifier is used to output hex floating-point literals in the disassembly. The Zfa specification is frozen (and has passed public review). It is available as a chapter in "The RISC-V Instruction Set Manual: Volume 1": https://github.com/riscv/riscv-isa-manual/releases bfd/ChangeLog: * elfxx-riscv.c (riscv_multi_subset_supports): Add instruction class support for 'Zfa' extension. (riscv_multi_subset_supports_ext): Likewise. (riscv_implicit_subsets): Add 'Zfa' -> 'F' dependency. gas/ChangeLog: * config/tc-riscv.c (flt_lookup): New helper to lookup a float value in an array. (validate_riscv_insn): Add 'Wfv' as new format string directive. (riscv_ip): Likewise. * doc/c-riscv.texi: Add floating-point chapter and describe limiations of the Zfa FP literal parsing. * testsuite/gas/riscv/zfa-32.d: New test. * testsuite/gas/riscv/zfa-32.s: New test. * testsuite/gas/riscv/zfa-64.d: New test. * testsuite/gas/riscv/zfa-64.s: New test. * testsuite/gas/riscv/zfa-fail.d: New test. * testsuite/gas/riscv/zfa-fail.l: New test. * testsuite/gas/riscv/zfa-fail.s: New test. * testsuite/gas/riscv/zfa.d: New test. * testsuite/gas/riscv/zfa.s: New test. * testsuite/gas/riscv/zfa.s: New test. * opcode/riscv-opc.h (MATCH_FLI_H): New.

2023-06-27 RISC-V: Support Zicond extensionPhilipp Tomsich1-0/+8
This implements the Zicond (conditional integer operations) extension, as of version 1.0-rc2. The Zicond extension acts as a building block for branchless sequences including conditional-arithmetic, conditional-logic and conditional-select/move. The following instructions constitute Zicond: - czero.eqz rd, rs1, rs2 => rd = (rs2 == 0) ? 0 : rs1 - czero.nez rd, rs1, rs2 => rd = (rs2 != 0) ? 0 : rs1 See https://github.com/riscv/riscv-zicond/releases/download/v1.0-rc2/riscv-zicond-v1.0-rc2.pdf for the proposed specification and usage details. bfd/ChangeLog: * elfxx-riscv.c (riscv_multi_subset_supports): Recognize INSN_CLASS_ZICOND. (riscv_multi_subset_supports_ext): Recognize INSN_CLASS_ZICOND. gas/ChangeLog: * testsuite/gas/riscv/zicond.d: New test. * testsuite/gas/riscv/zicond.s: New test. include/ChangeLog: * opcode/riscv-opc.h (MATCH_CZERO_EQZ): Define. (MASK_CZERO_EQZ): Define. (MATCH_CZERO_NEZ): Define, (MASK_CZERO_NEZ): Define.
