C compiler in C++

This is a learning project for Crafting interpreters.

Most part of C is supported. Support for pointer is hacky. See tests/ for the supported part.

For which part is supported, see test code under tests/.

Graphviz binary and llvm must be installed. llvm headers are required. Linker commands are dependent on platform and distribution. See the link function in object.cc.

make

make test

./clox SOURCE

And then ./a.out, ./output.o, ./output.dot and ./output.png are genereated.

./a.out is the executable file.

./output.o is the object file.

./output.dot is the dot description of the AST.

./output.png is the graph generated according to ./output.dot

Generally speaking, the type system is a whole mess. Basic types (int, double, char, bool) works, and arrays should work in most case.

Other things are like:

• Pointer is not supported.
• Pointer arguments are supported but in a hacky way.
• Array is partly supported.
• Struct and unions are not supported.
