The RVA23U64 mandatory profile is the 2023 application-class baseline for 64-bit RISC-V. It includes Zba/Zbb/Zbs bit-manipulation, Zfhmin half-precision, Zawrs wait-on-reservation-set, Zic64b/Ziccamoa cache operations, the full V vector extension, and several crypto profiles. riscv64gc-unknown-none-elf exists but targets generic-rv64 without any of these extensions. The corresponding Linux target riscv64a23-unknown-linux-gnu was added previously; this adds the bare- metal none-elf variant for kernel and runtime development targeting modern server-class RISC-V hardware. Target properties mirror riscv64gc-unknown-none-elf: LLD linker, static relocation model, medium code model, panic=abort, no std. Adds KernelAddress and ShadowCallStack sanitizer support. Tier: 3 (no host tools, no std)
