[Tinycc-devel] incremental compilation

[brian]

Well, I've had a play with tinycc today, and added (fairly primitive) 
incremental compilation (for the memory target).

The *addenda stuff is a bit of a hack, and should be cleaned up soon.

If anyone is particularly interested the next stage involves rendering 
into custom memory arenas, and after that - type introspection.

--- example of of incremental in-memory compilation ---

char my_program[] = "int fib(int n) { if (n <= 2) return 1; else return 
fib(n-1) + fib(n-2); }";
char my_program2[] = "int noo() { return printf(\"This is noo! (fib = 
%d)\\n\", fib(32)); }";

int main(argc, char **argv)
{
   TCCState *s;
   int (*func)(int);
   int (*func2)(void);
   s = tcc_new();
   tcc_set_output_type(s, TCC_OUTPUT_MEMORY);
   tcc_compile_string(s, my_program);
   tcc_relocate(s);
   func = tcc_get_symbol(s, "fib"); printf("fib 32 = %d\n", fib(32));
   tcc_compile_string(s, my_program2);
   tcc_relocate_addenda(s);
   func2 = tcc_get_symbol(s, "noo");
   if (func2) func2();
   tcc_delete(s);
   return 0;
}
