Provides comprehensive ISA coverage across 50+ RISC-V extensions (base, floating-point, vector, cryptographic, and vendor-specific) with both 32 and 64-bit instruction support. Uses a straightforward assembler API similar to Xbyak, allowing developers to emit machine code directly into buffers at runtime with no external dependencies beyond the C++ standard library. Targets performance-critical scenarios like JIT compilation, dynamic binary instrumentation, and kernel development on RISC-V platforms.
