A small C compiler written in Python for learning purposes

Overview

SmallerC

A small C compiler written in Python. Generates x64 Intel-format assembly, which is then assembled and linked by nasm and ld.

Features

See the tests folder for examples that compile. The function_test.c test is representative of the range of SmallerC.

  • Math
    • Operations: +, -, *, /, %, ++, --, &&, ||, !
    • Assignment: =, +=, -=, *=, /=, %=
    • Comparison: ==, !=, <, <=, >, >=
  • int type variables
  • Control structures:
    • if
    • while
    • for
    • break
    • continue
  • Pointers (referencing and dereferencing)
  • Arrays
  • Function definition and calling
  • \* ... */-form comments
  • print statement: print n outputs the integer n to stdout.
    • This isn't in the C spec, but I included it to facilitate outputting values from the program; SmallerC is nowhere near being able to compile the stdio C libraries.
