Yes, but the proper approach would be:
Dear Alpha guys,
I've compiled all the C code on the Alpha, but I know the xyz.S file
needs changing. I don't know AXP asm to save my life, but here is
the diff I had to do in the i386 xyz.S file:
[ diff ]
What this change does (for those AXP asm hackers that don't read
Intel) is __________. What would be the AXP change needed?
What we got:
I've developed the proc splitting on i386 and it works for me.
The diffs are at http://_______. AXP hackers, go to it.

That is fine, but the -current AXP developers are a small lot. They need
to have up-front leg work done, so the limited time they do have (where
many i386-only people are tugging at their sleeves) is well spent.
