My error, I mis-read the statement.
My mind was somewhere else while my hands were typing.
This entire thread has spured me to dig out my project notes from
a globally optimizing, meta-assembler done about 23 years ago.
I am doing a re-write of the principles and concepts with GCC
in mind. I'll let the list know when I have the draft finished.
If GCC really isn't doing better than a W.A.F.G. in this area,
perhaps it will help.
