GCC 14 Adds Support For RISC-V Vector Crypto Extensions


The GNU Compiler Collection 14 (GCC 14) will feature support for the new RISC-V processor ISA vector cryptographic extensions.

Merged on Friday was the code that's been in the works for months for implementing various RISC-V vector crypto extensions in GCC. The extensions now enabled include:
- Zvbb
- Zvbc
- Zvkg
- Zvkned
- Zvkhn[a,b]
- Zvksed
- Zvksh
- Zvkn
- Zvknc
- Zvkng
- Zvks
- Zvksc
- Zvksg
- Zvkt
This follows support added to LLVM 17 back in March for these extensions.

More details on these extensions can be found via the RISC-V Cryptography Extension GitHub repository.

As usual with the GCC feature releases on an annual basis, look for GCC 14 stable to debut in early 2024.
