Subject: forbid to set current_block to Bad
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=a10a4d1083b97c65a7fd6ee0fff8c075fa8c4ea3;p=libfirm

forbid to set current_block to Bad

This was used as a hack to mark unreachable code by some people, but it
is prefered to simply use a new Block without predecessors, or set NULL
if you have to.
