Reduced test-case:
$ cat m68.i
struct {
int : 12, : 11, k : 9;
long l;
} sH;
int sH_3___trans_tmp_1, sH_3_i, sH_3_v;
unsigned sH_3_s;
void
sH_3() {
char *p = (char *)&sH;
sH_3_i = 0;
for (; sH_3_i < sizeof(sH); ++sH_3_i) {
sH_3_s *= 515245;
sH_3___trans_tmp_1 = sH_3_s % 2048;
*p++ = sH_3___trans_tmp_1;
}
sH.k = sH_3_v;
}
$ ./xgcc -B. m68.i -c -O3
