Actually, the testcase in #1 still fails on gcc-4.4. Looks like gcc-4.4 (and
earlier) need to use a bigger blockage.

Yes, this could be fixed in the Thumb back-end by doing it the same way as the
ARM back-end does. However, I still think that is papering over a subtle
problem in the scheduler. This is an insidious problem

For 4.0 and above your sample code works but that is a different issue.
Here is a testcase which fails for 4.0 and above:
int find_num(int i)
{
int arr[5] = {0, 1, 2, 3, 4};
return arr[i];
}
