Adding Zalasr
2023-10-19Making explicit that the aq bit is set for load-acquire, rl bit is set for ↵brs1-8/+8
store-releasee
2023-10-18Changing it so Zalasr has one bit hardcoded for each, to reduce opcode ↵brs1-8/+8
confusion hopefully
2023-10-18Adding load-acquire/store-release. Note they are written here as `lb.` for ↵brs1-0/+8
the load-acquire byte (so `lb.aq` and `lb.aqrl`), I'm not sure that will work but it passes the tests here.

Remove unratified `Zvamo` instructions from `rv_v`
2023-10-16Remove unratified 'Zvamo' instructions from rv_vTsukasa OI1-41/+0
If this is the only thing happening, I would have just moved those instructions to unratified/rv_zvamo. The reason I didn't is, there is the 'Zabha' extension (containing subword AMO instructions) in the fast track and 8-bit vector AMO instructions conflict with it.

Because neither priv and unpriv isa mentions dret, and debug is lived in a standalone spec, move dret out from rv_system, while putting it into rv_debug

Support for Zvk, Vector Cryptography Extensions
2023-05-01Support for Zvk, Vector Cryptography ExtensionsEric Gouriou14-8/+218
Add encodings for all instructions in the Zvk extensions: - Zvbb, Vector Bit-manipulation instructions used in Cryptography, - Zvbc, Vector Carryless Multiplication - Zvkg, Vector GCM/GMAC instruction for Cryptography, - Zvkned, NIST Suite: Vector AES Encryption & Decryption (Single Round), - Zvknha, Zvknhb, NIST Suite: Vector SHA-2, - Zvksed, ShangMi Suite: SM4 Block Cipher Instructions - Zvkssh, ShangMi Suite: SM3 Hash Function Instructions Add two "shorthand" extensions: - Zvkn: NIST Suite, imports Zvbb, Zvbc, Zvkned, and Zvknh - Zvks: ShangMi Suite, imports Zvbb, Zvbc, Zvksed, and Zvksh Three new fields are listed in constants.py: - 'zimm5', used to encode round constants (Zvkns, Zvksed, Zvksh), and 5-bit shift constant (vwsll.vi in Zvbb) - 'zimm6hi, zimm6lo', used to encode the 6 bits rotate amount in vror.vi. The Zvk instructions – with the exception of Zvbb, Zvbc – reside in the P opcode space. Some encodings conflict with proposed instructions in the P extension (packed SIMD). Zvk and P are exclusive of each other, no implementation will implement both. Conflicting P instructions are marked as pseudo of the Zvk instructions. The encodings match the current documentation of the specification at <https://github.com/riscv/riscv-crypto/tree/master/doc/vector>, at Version v0.9.1, 25 April, 2023 (Freeze Candidate).
