C to Brainfuck

This is a compiler from a subset of C to highly unoptimized Brainfuck. There are no support for dynamic allocations, pointers and global variables. Everything else can be derived from the present:

• Types:

  • int -- the size of bf machine cell, e.g. 8 bits
  • T[N] -- arrays of type T with statically known size N
  • struct { T f; ... } -- custom structs

  Types can be defined as usual with typedef struct { .. } S;

• Functions:

  • T func(T arg, ...); -- declaration
  • T func(T arg, ...) { .. } -- definition

• Statements:

  • T x = expr -- local variables declarations
  • x = expr -- assignments
  • if (expr) { .. } else { .. } -- conditionals
  • while (expr) { .. } -- loop construcions
  • func(expr, ...) -- function calls

• Expressions

  • x -- refering to local variables and arguments
  • expr.field -- accessing structures' fields
  • x[expr] -- indexing arrays with custom expressions
  • func(expr, ...) -- calling functions
  • expr + expr, expr - expr -- wrapping on overvflow addition and subtraction

All features are presented in example implementation of Rule 110 (Run compiled version).
