Subject: Remove unnecessary dependency edge from the IncSP, which destroys the stack frame... 
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=a7d7eff700f5602dacd03a3e555cbce09b3ca360;p=libfirm

Remove unnecessary dependency edge from the IncSP, which destroys the stack frame, to the final memory Proj.  Most probably it is unnecessary since Projs are not scheduled anymore.
