------- Comment #9 from bonzini at gnu dot org 2006-01-23 17:06 -------
That's not the correct fix. Every user of bsi_after_labels does a
bsi_insert_after, and that inserts after the first executable statement (rather
than before) if there is no label in the basic block.

This really a latent bug in bsi_after_labels.

The testcase starts failing with this patch from irar:
http://gcc.gnu.org/ml/gcc-cvs/2005-07/msg00888.html
Ira, if this was a merge from a branch then I can do a regression hunt on
that branch, if that would be useful.
