gcc44-pr39124.patch
The problem is that remove_path first calls remove_bbs and afterwards
cancel_loop_tree. The first call removes all bbs from one loop (a loop inside
of another loop that has niter == 0 and is peeled completely to nothing) and
the second attempts to remove it. But, get_loop_body asserts the loop has at
least one bb, which is not true after all its bbs have been removed.
This patch fixes this by first calling cancel_loop_tree and afterwards
remove_bbs. E.g. tree-loop-distribution.c also calls it in this order, first
cancel_loop_tree, then delete_basic_blocks. Also cancel_loop comment suggests
that bbs should be removed afterwards.
