A Toy C Compiler

Dcc - A Toy C Compiler

This was my first compiler attempt. In retrospect, i should have picked a smaller language. Although it's very flawed, there are some good parts. The poorest part is the code generation.

It's pure C and produces X86 Windows PE executable independently of any third party software such as assembler or linker. Parsing is done with a mix of Recursive Descent Parser and operator-precedence parser (Shunting Yard).

Assembler is very limited and linker generates import table only for C standard library (msvcrt.dll).

implemented subset

• Arbitrarily nested if-else for while
• Recursive calls
• Basic pointer access
• int and char types (pointers included)
• String literals

Pointer arithmetic and preprocessor are not implemented along with many other features. Take a look at the examples.
