Re: Data Structure Reorganizing Optimizations

        Now arguing that structure field rearrangement could make processor memory
        management task easier is nice, but you haven't clearly demonstrated a
        benefit. If the source code needs fields in particular locations, the
        optimization of rearrangement will break the application. If the locations
        are not important, the application programmer may have already hand
        optimized the structure, so how much better is the compiler going to do
        this???


The almost 2X benefit demonstrated by Alvy LeBeck isn't good enough
for you?


(Personally, I have spent much of my career optimizing other people's
code. Rearranging data structures is part of my standard book of
tricks. I am only trying to make it possible for compilers to do what
a skilled human programmer does as a matter of course.)
