# codewars-riscv64
Container image for RISCV64 assembly used by CodeRunner.
## Prerequisites
The container host must support [QEMU user-mode emulation](https://www.qemu.org/docs/master/user/main.html). Install the statically linked binaries for QEMU user-mode emulation **on the container host**, e.g. on Ubuntu 22.04:
```bash
$ sudo apt update && sudo apt install qemu-user-static
```
## Usage
```bash
$ ./bin/run
```
Specify a container engine (default: `docker`) with environment variable `CONTAINER_ENGINE`. E.g. with Podman:
```bash
$ 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/`:
```bash
$ ./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
```bash
$ docker build --platform linux/riscv64 -t ghcr.io/codewars/riscv:latest .
```
