Compile sourir to C.

The translation should be relatively straight forward. To give you an idea, lets consider the following program:

x = read()
while x > 10:
  x/2
print x

In sourir this would be somthing like

  mut x
  read x
l:
  br x > 10 b e
b:
  x <- x / 2
  goto l
e:
  print x

Which can be easily compiled to the following C program:

void main() {
l1: {} int x;
l2: { char t[20]; gets(&t); x = atoi(t); }
l3: { if (x > 10) {goto l4;} else {goto l6;} }
l4: { x = x / 2; }
l5: { goto l3; }
l6: { printf ("%d\n", x); }
}

Really subtle trolling of C programmers, the buffer overflow in the compiled code example ;-)

writing the exploit is an exercise left to the reader
