SubjectRe: Linux on Merced

At least one third of the UltraPenguin hackers did not have any SPARC
experience one year before. He learned SPARC assembly by looking at
the output of cc -S. This same guy is also responsible for Linux
having the fastest memcpy operations on the SPARC.

It would be much easier to get access to a merced machine.

The UltraPenguin team had to do some extensive hacks gcc/binutils to
get the thing up and running on the SPARC-v9 which is the 64-bit
extension of the SPARC architecture.

Porting the GNU gcc/binutils to a new platform is not a difficult
task. If 3 hackers could get the Ultra-64 port up and running before
Sun could port Solaris to their SPARC-64 chip, imagine what thousands
of Linux hackers can do with the intel 64 bit chip.
