C/C++ to EO translator

This is a translator of C/C++ to EOLANG. The 1st step is C to EOLANG S2S compiler.

C2EO

Semantic-preserving translation of C programs to EOLANG programs.

• Document with C2EO transform examples

• Project for playing with examples

• Tests

1. Install LLVM + CLANG

$ wget https://github.com/llvm/llvm-project/archive/refs/tags/llvmorg-12.0.1.tar.gz
$ mkdir llvm-clang
$ tar -C llvm-clang -xvf llvmorg-12.0.1.tar.gz

 

2. Build LLVM + CLANG

$ cd llvm-clang
$ # rm -rf build
$ mkdir build && cd $_
$ cmake --no-warn-unused-cli -DBUILD_SHARED_LIBS:STRING=ON -DLLVM_TARGETS_TO_BUILD:STRING=X86 \
  -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE "-DLLVM_ENABLE_PROJECTS:STRING=clang;compiler-rt" \
  -DCMAKE_BUILD_TYPE:STRING=Debug -DLLVM_OPTIMIZED_TABLEGEN:STRING=ON \
  -DLLVM_USE_SPLIT_DWARF:STRING=ON -DLLVM_USE_LINKER:STRING=gold ../llvm -G Ninja
$ cmake --build . --config Debug --target all -j 10 -- -j1 -l 2

 

3. Install C2EO

$ cd ../..
$ git clone https://github.com/kreofil/C2EO-draft.git c2eo

 

4. Configuration C2EO

Set PATH_TO_LLVM_SOURCE variable to the LLVM+CLANG directory when invoking CMake;

Set -DCMAKE_BUILD_TYPE variable to the Debug state, if you want to output the values of all global variables (works only for ../kam/src);

$ cd c2eo
$ # rm -rf build
$ mkdir build && cd $_
$ cmake -DCMAKE_BUILD_TYPE=Debug -DPATH_TO_LLVM_SOURCE=~/path/to/llvm-clang/ \
  -DCMAKE_DEPENDS_USE_COMPILER=FALSE -G "CodeBlocks - Unix Makefiles" ../al/src
$ cmake --build . --target c2eo -- -j 6

 

5. Run

Use -- at the end of command below to skip all errors;

Use -d to set the path to output directory;

$ ./c2eo file-name.c -- -d path/
