Chris’ C Compiler

An attempt to write an (educational) C(17) compiler. Provides a Lexer, Parser and a Code Generator (x86_64).

The compiler driver uses GCC’s preprocessor and assembler/linker, to help turning the code into an executable.

Supports:

• Return
• Unary operators (!, ~, -)
• Binary arithmetic and logical operators (+, -, *, /, %, <<, >>, &, |)
• Logical and relational operators (&&, ||, <, >, <=, >=, !=, ==)
• Local variables (int)
• Compound assignments and post/pre (inc/dec)rement (+=, /=, <<, … and ++<var>, <var>– …)
• If Statements (and goto + labeled statements)
• Compound Statements
• Loops and Switch Statements
• Function calls
• File scope
• Long type
