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. > I think asking him to do this without knowledge of register > save/restore and allocation plocies of the FreeBSD Alpha port > is rather unfair. 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. -- -- David (obrien@FreeBSD.org) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
