Subject: Fix some forgotten cases in the 64bit lowerer: The lower 32bits of a 64bit operation... 
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=492fde34e04d04a03994f006b468688c062935c6;p=libfirm

Fix some forgotten cases in the 64bit lowerer: The lower 32bits of a 64bit operation are always unsigned.
