codewars-riscv64

Container image for RISCV64 assembly used by CodeRunner.

Prerequisites

The container host must support QEMU user-mode emulation. Install the statically linked binaries for QEMU user-mode emulation on the container host, e.g. on Ubuntu 22.04:

$ sudo apt update && sudo apt install qemu-user-static

Usage

$ ./bin/run

Specify a container engine (default: docker) with environment variable CONTAINER_ENGINE. E.g. with Podman:

$ CONTAINER_ENGINE=podman ./bin/run

Specify an example under the examples/ directory to run (default: multiply) by passing a command-line argument. E.g. to run the example under examples/multiply-failing/:

$ ./bin/run multiply-failing

Examples

• multiply (default): Example of multiply function with fixed and random tests
• multiply-failing: Like multiply, but with a failing implementation
• syntax-error: An assembly program with syntax errors. Also demonstrates that it shouldn't be possible to cheat by replacing assembly with C
• invalid-regname: An assembly program with an invalid register name t7 (RISCV64 temporaries only range from t0 to t6)

Building

$ docker build --platform linux/riscv64 -t ghcr.io/codewars/riscv:latest .
