coord-e / ccc

optimizing compiler for a subset of C language

ccc

a work-in-progress compiler for a tiny subset of C language.

ccc is intended to be an optimizing compiler that produces code which is faster than gcc -O1 does, and compiles faster than that.

Roadmap

• support C11 features
  • arithmetic operations
  • pointer arithmetic
  • arrays
  • type checker
    • support type qualifiers
  • implicit type conversions
  • initializers
    • scalar
    • array
    • struct
    • designated initializers
  • a copy of struct
    • local assignment
    • argument
    • return value
  • preprocessor
  • self-hosting
  • complex declarators
  • alignment specifiers
  • float-point values
• optimizations
  • linear scan register allocation
  • naive mem2reg
  • constant folding
  • copy propagation
  • dead code elimination
  • tail call optimization
  • loop unwinding
• misc
  • improved error messages
  • better support of debuggers
  • support targets other than x86_64

Development

To build ccc, run:

make

You'll see a compiled binary under ./build/.

You can add DEBUG=0 to get an optimized build of ccc.

To run tests, use test target:

make test
