CIL (was: Re: [Tinycc-devel] type cast prob.)

Salut Fabric,

I found CIL that translate C to C. 
The resulting C code is a subset of C.

The program "main(){float x; (float)x=(float x);}"
translate to:

$ cat  t5cil.c
/* Generated by CIL v. 1.0.4 */
/* print_CIL_Input is true */

# 2 "t5.c"
int main(void) 
{ float x ;

  {
# 5
  x = (float )((int )x);
# 5
  return (0);
}
}
$tcc -c t5cil.c
$

CIL is at http://manju.cs.berkeley.edu/cil/

Sylvain.
