How to build

note: due to we need latest bison, so you may need compile from source and add soft link under /usr/bin/bison to make sure cmake find it.

sudo apt install cmake flex ninja-build clang
git clone git@github.com:WLFJ/T-Lang.git
cd T-Lang
git submodule update --init --depth 1
mkdir 3rdparty/llvm-project/build && cd 3rdparty/llvm-project/build
cmake -G Ninja ../llvm \
   -DLLVM_ENABLE_PROJECTS=mlir \
   -DLLVM_BUILD_EXAMPLES=ON \
   -DLLVM_TARGETS_TO_BUILD="X86;NVPTX;AMDGPU" \
   -DCMAKE_BUILD_TYPE=Release \
   -DLLVM_ENABLE_ASSERTIONS=ON \
   -DLLVM_ENABLE_RTTI=true
ninja
cd -
mkdir build && cd build
cmake ..
cmake --build . -j$(nproc)

How to use

1. compile project.
2. write your source code saved in test.tc.
3. run following command:

chmod +x build/tc && ./tcc test.tc && ./a.out

TO-DO

• A simple (hello-world example) bison example.
• A flex.
• A AST dumper.
• CMake
• Migrate build system from GNU make to CMake.
• Mem safer (avoid useing new directly, instead of unique_ptr?). No, we'll use AST from ToyLang.
• Simplify yy and ll file. Seems it's already clean yet.
• Freeze MLIR into 3rdparty, and include it into CMakeLists. (Should we build it automatically ?).
• Add backend support.
• Support print in grammar.
• Add TIR, make them all runnable.
• Add variable dec like var a = 1;. (partial, id bind in grammar is needed.)
• Add RTTI support cmd.
• Dump llvm::Module into file. using JIT instead.
• Add math calc. (for + *)
• Add function fully support. (arbitary argument, return value, caller, callee).
• For now sub function must have return type.
• Add advanced operator (transpost etc.)
• grammar confict fix (binop precident).
• support redundent tensor decl.
• support none value variable declearation.
• research how ir generated.
• add linalg opt layer.
• writing some ref ;P.
• Add linalg.generic like expr support. like this:

# a -> [1, 2, 3, 4] then b -> [ [1, 2], [3, 4] ]
# usage: [[ tile(a) ]]
# reshape
lin tile(a<m>) {
  map {a<i> -> <m>, b<j, k> -> <i / k, i % k>}
  (a) {
    a;
  }
} -> b<n, k>

• support more binop (-, .)
• FileCheck (LLVM is needed).
• Automatic Test.(Maybe cmake test).
• Add remain supported expr.
