Thanx for your replies.
I am working on 2.95.3+motorola's version of altivec stuff added in
2.95.2+lots of changes already done by me :) (any comments on this are
welcomed :))
I Commented out the decrement_and_branch_on_count template, didnt work;
commented out ctrsi template, didnt work; commented out the offending
template that was showing up in the .greg file "ctrsi_internal1",
worked.
didnt work = The ctr instructions still remained in the O2 optimized
output.
So it works now but can somebody explain what just happened over here?
