--- Comment #1 from Jonas Paulsson <pauls...@linux.vnet.ibm.com> ---
Tried to fix this, but it turns out that empty blocks with either no
predecessors or successors are the only empty blocks left, which seems to be
difficult / unnecessary to get rid of. For the first block in function,
removing it triggers an assert that a loop header should not be first block in
function. As to empty blocks without successors, I am not sure if there could
still be a jump to such a block but it however seems harmless.
So, I close this bug without any changes, sorry for spamming.
