Re: [dev] Re: Needed patches for building on PPC?
Hi,
Just to point out, I will help any volunteer who already knows the abi
(register passing, stack frame alignment, etc) figure this out and help
them write it. I just don't want to move to gcc 3.X before 3.1 is
released and OpenOffice.org 1.0 is released.
So anyone interested in "learning" the insides fo exception handling and
vitrual method tables under gcc 3.X would be welcomed!
