Colgm Compiler Project

Repo Content

• bootstrap : available now, features not stable these days, but welcome to try.
• src : bootstrapped compiler, not available now (lexer and parser is ready).
• test: test cases.

Bootstrap Compiler

• macos-aarch64-nightly-build

• linux-x86_64-nightly-build

• windows-x86_64-nightly-build [WIP]

Bootstrap compiler locates at {repo_path}/bootstrap, written by C++(-std=c++17):

Use these commands to build the bootstrap compiler, use -DCMAKE_BUILD_TYPE=Debug if want debug version:

mkdir build && cd build
cmake ../bootstrap -DCMAKE_BUILD_TYPE=Release && make -j

The executable is located as build/colgm.

Then use this command to build bootstrapped compiler:

make colgm.ll

The bootstrapped compiler should be {repo_path}/colgm.ll. If having lli(llvm jit interpreter), you could try this to execute bootstrapped new compiler:

lli colgm.ll main.colgm --library .

LLVM jit interpreter maybe unstable on some platforms, if lli crashed, try using clang to build out.ll to executable:

clang colgm.ll -o colgm

Hello World

Hello world example is available in bootstrap:

use libc::puts;

pub func main() -> i64 {
    puts("hello world!");
    return 0;
}

Tutorial

See simple tutorial in bootstrap/README.md.

TODO

1. support foreach/forindex, may not support in bootstrap compiler:
   • forindex loop, container should have size() method
   • foreach loop, container should have iterator-like stuff
2. llvm debug info, may not support in bootstrap compiler
3. develop bootstrapped compiler
4. array type like [i32; 128]
