# LLVM with 6502 backend
|
|
|
|
This is an [LLVM](http://llvm.org/) fork that tries to implements an [MOS
|
|
6502](https://en.wikipedia.org/wiki/MOS_Technology_6502) backend.
|
|
|
|
## Build
|
|
|
|
Refer to the [Getting
|
|
Started](http://llvm.org/docs/GettingStarted.html#getting-started-quickly-a-summary)
|
|
guide from LLVM.
|
|
|
|
A quick way to start (on Linux):
|
|
|
|
* Clone this repository
|
|
* Run inside directory:
|
|
|
|
```bash
|
|
mkdir build
|
|
cd build
|
|
cmake .. -DLLVM_TARGETS_TO_BUILD:STRING="X86;Mos6502"
|
|
make -j4
|
|
```
|
|
|
|
If you want to build more targets, append them to the `LLVM_TARGETS_TO_BUILD`
|
|
variable. Adjust `-j` option of `make` in case you have more processor cores.
|
|
|
|
## Install
|
|
|
|
Run `make install` as usual.
|
|
|
|
## Usage
|
|
|
|
*TODO: Write how to convert from C/C++ with Clang to IR and 6502 assembly code.*
|
|
|
|
## Tests
|
|
|
|
To run regression tests for the MOS 6502 target, run from `build/`
|
|
|
|
```bash
|
|
make check-llvm-codegen-mos6502
|
|
```
|
|
|
|

|
|
Guide](http://llvm.org/docs/TestingGuide.html).
