Subject: show optimisation warnings in ia32 conv/conv opts
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=9ba29c4c7e3993314251f3b5489a4789badba4c9;p=libfirm

show optimisation warnings in ia32 conv/conv opts

The middleend should optimize all these cases, it does so for 99% of
them already. There are just some cases where ands get transformed into
conversions which the middleend doesn't catch yet.
