**Please note this is just my little toy and could be abandoned any time**
## Build instruction
**Instructions below assume you use Ubtuntu22**
### Prerequisites
```bash
sudo apt install cmake clang ninja-build -y
pip3 install --user conan
```
### Build
```bash
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Debug \
-DCMAKE_C_COMPILER=clang \
-DCMAKE_CXX_COMPILER=clang++ \
-DCMAKE_EXPORT_COMPILE_COMMANDS=YES \
-DJCC_USE_ASAN=ON \
-GNinja ../ && ninja
```
`-DJCC_USE_ASAN=ON` means enable the address sanitizer, which might be helpful to catch some memory bugs.
### Run tests
```bash
ninja test
```
### Usage
> Note JCC is still in the very early stage, so don't expected it can handle everything correctly :)
- Dump the AST tree of the program.
```bash
./jcc test.c --ast-dump # Note you can only pass the flag in the end!
```
- Generate the assembly.
```bash
./jcc test.c # It will produce a.out
```
