Dear all,
i'm using cil-1.5.1 and would like to know if it is possible to emit a
three-address code representation that is actually flattened. For
instance, while statements should not be allowed by replaced
equivalent code using goto.
I have used --domakeCFG and --dosimplify, however the generated C code
is not flattened; hierarchy and some high-level features are visible.
The same applies to if-statements; is it possible to emit
if-statements only as conditional jumps and not as basic block guards?
I have an example to showcase what I mean, which comprises of a simple loop.
// loop1.c (initial C source)
for (ix = 0; ix < inp; ix++)
;
// loop1.cil.c (generated by CIL)
ix = 0;
{
while (1) {
while_continue: /* CIL Label */ ;
if (! (ix < inp)) {
goto while_break;
}
ix ++;
}
while_break: /* CIL Label */ ;
}
// loop1.nac.c (lower-level C for loop1)
#include <stdio.h>
#include <math.h>
#include "main.h"
ix = 0;
goto D_1362;
D_1361:
ix = ix + 1;
goto D_1362;
D_1362:
if (ix < inp) {goto D_1361;} else {goto D_1363;}
D_1363:
Best regards
Nikolaos Kavvadias
