static-globals 0.0.2

A C/C++ code instrumenter makes global variables static

make-globals-static is used in DEAD. It makes global variables and functions (except main) static.

To build just the clang tool

Prerequisites: cmake, make, clang/llvm 13/14.

mkdir build
cd build
cmake .. 
cmake --build . [--parallel]
cmake --install . --prefix=/where/to/install/

Usage

cat test.c
int b;
int foo(int a) {
    return a + b;
}

int main(){
    return foo(2);
}


make-globals-static test.c --


cat test.c 
static int b;
static int foo(int a) {
    return a + b;
}

int main(){
    return foo(2);
}

Python wrapper

pip install static-globals

To use the instrumenter in python import from static.instrumenter import annotate_with_static: def annotate_with_static( program: ProgramType) -> ProgramType

Building the python wrapper

Local build

./build_python_wheel_local.sh #this will build the current branch
pip install .

Docker based build

docker run --rm -e REVISION=REV -v `pwd`:/io theodort/manylinux-with-llvm:latest /io/build_python_wheel_docker.sh

This will build multiple wheels for REV with multiple python versions. The output is stored in the wheelhouse directory. The docker image is based on https://github.com/thetheodor/manylinux-with-llvm.
