README
rjit is a toy runtime assembler written in Rust.
By using this, you can run or test the assembly directly without linking process.
## Feature
* x86_64 assembly (**NOT** 32bit)
* [AT＆T](https://csiflabs.cs.ucdavis.edu/~ssdavis/50/att-syntax.htm) syntax support.
## Quick Start
```
$ cargo build --release
// exit.s will exit with code 42.
$ ./target/release/rjit --file=./examples/exit.s
// check exit code.
$ echo $?
-> 42
```
## Debug
If you want to check internal process , use gdb.
## Supported Assembly Syntax
- [x] nop
- [ ] add
- [ ] sub
- [x] mov
- [x] ret
- [x] int
- [x] syscall
also, please check examples directory.
## Restriction
* input is one assembly(.s) file.
* no libc support.
* but I'm thinking of adding my own implementation for libc that doesn't need the linking process. (ex: printf, malloc, etc...)
