LLVM with 6502 backend

This is an LLVM fork that tries to implements an MOS 6502 backend.

Build

Refer to the Getting Started guide from LLVM.

A quick way to start (on Linux):

• Clone this repository
• Run inside directory:

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/

make check-llvm-codegen-mos6502

For more information on the LLVM test suite, refer to the Testing Guide.
