[Coco] Devastated. Long term OVCC project falls short

[Joel Rees]

Random thoughts.

Intel has been so busy tuning the open source compilers and the Intel
silicon to each other it must be no surprise to find that writing
large-scale assembler code by hand is going to conflict in fundamental ways
with all the cheats Intel puts in things. Some of the problems (register
width, segment layout vs. caching, wrapper ABI) have been mentioned, and
there is more.

It's not even worth trying to optimize any Intel processor code at the
assembler level, except for some minor in-lining.
