Description

Posting because I cannot find mention anywhere

I have seen that mono supports the RISC-V architecture but cannot find anything relating to .NET 5 support for RISC-V. Are there any plans to support said architecture on future releases of .NET like ARM64 has been added?

Contributor guide

Research direction
Examine the current JIT and AOT compilation pipeline to identify where RISC V code generation would be inserted, starting with the RyuJIT codebase. Look at existing architecture specific implementations (e.g., ARM64) for patterns to follow. Assess the runtime's platform abstraction layer (PAL) for low level OS support. Investigate the .NET linker and crossgen tools for AOT scenarios. Review the Mono runtime's RISC V support for potential code sharing.
