...

Go is a programming language designed for simplicity, reliability, and efficiency.

• Go Homepage

...

• OpenJDK Homepage

• OpenJDK github repository

RISC-V status

The OpenJDK RISC-V Port project has been approved by the OpenJDK community [1] and Fei Yang from Huawei Technologies is leading this new project now [2].

...

PHP is a programming language targeting web development.

• PHP homepage

RISC-V status

The PHP interpreter works on RISC-V. However, certain features, such as the PCRE JIT, are not ported yet and there are no RISC-V specific optimizations in the codebase at the moment. Thus optimal performance cannot be achieved right now.

...

Rust is a programming language designed for performance, reliability and productivity. It relies on LLVM for generating code.

• Rust Homepage

• Rust Book

RISC-V status

Rust has tier 2 support for RISC-V RV64 (riscv64gc-unknown-linux-gnu) since 1.42.0 (2020-03-12). RV32 is supported, but currenlty does not have a complete standard library.

...

• Rust Embedded Working Group

• Embedded Rust Book

RISC-V status

Since Embedded Rust does not require Rust’s standard library (no_std), more RISC-V platforms are available than for a full Rust runtime.

...
