c-compiler

This is a mini C compiler that compiles a subset of C programming language.

Development

Docker used for development and testing:

• make buildImage to build the Docker image for development and testing
• make docker to launch the container
  • Inside the container, make main to build the compiler
  • make test to run tests

Actual source code is inside the /compiler directory. Test source code and sample source codes that can be compiled by this compiler are inside the /compiler/test directory.

Tests

Tests located in the /compiler/test directory

Run test

make test to run the /compiler/test.sh file to compile /compiler/test/main.c and run it.

Running time comparison

make bench to run the /compiler/test_bench.sh file.

Example output

/compiler/test/simple_loop.c:
