Well, yes, we do generate that code. However, the loop is unrolled
later on and the IR code on which the vrp complains later on actually is:
main ()
{
unsigned int ivtmp.27;
unsigned int pretmp.17;
int pretmp.16;
unsigned int pretmp.15;
unsigned int anz.0;
unsigned int D.1258;
char * D.1259;
int anz;
# BLOCK 2 freq:909
# PRED: ENTRY [100.0%] (fallthru,exec)
D.1259_28 = &formatstr[0][0];
printf (&"%d %s\n"[0], 0, D.1259_28);
D.1259_39 = &formatstr[0][100];
printf (&"%d %s\n"[0], 1, D.1259_39);
D.1259_50 = &formatstr[0][200];
printf (&"%d %s\n"[0], 2, D.1259_50);
D.1259_61 = &formatstr[0][300];
printf (&"%d %s\n"[0], 3, D.1259_61);
D.1259_72 = &formatstr[0][400];
printf (&"%d %s\n"[0], 4, D.1259_72);
D.1259_83 = &formatstr[0][500];
printf (&"%d %s\n"[0], 5, D.1259_83);
D.1259_94 = &formatstr[0][600];
printf (&"%d %s\n"[0], 6, D.1259_94);
D.1259_105 = &formatstr[0][700];
printf (&"%d %s\n"[0], 7, D.1259_105);
D.1259_116 = &formatstr[0][800];
printf (&"%d %s\n"[0], 8, D.1259_116);
D.1259_7 = &formatstr[0][900];
printf (&"%d %s\n"[0], 9, D.1259_7);
printf (&" %d\n"[0], 10);
return 0;
# SUCC: EXIT [100.0%]
}
