Message-ID: <10410181452.AA03986@vlsi1.ultra.nyu.edu> (raw)
A quick check of a random function handling component_refs shows they
will also be missing optimizations
Let me be very clear here:
If the nops aren't needed, they won't be there. So the question isn't
if they are needed or not. Rather, it's whether the expression should be
split up among statements.
Are you really arguing that it's more likely to miss optimizations if they
are in *one* statement than if they are in multiple statements? If so,
can you explain?
