Hi,

My /etc/mk.conf looks like:

-----
.ifdef BSD_PKG_MK

# pkgsrc only options

.else  # BSD_PKG_MK

COPTS?= -pipe ${DEFCOPTS}

# For cross-compiling
. if ${MACHINE_ARCH} == sparc
COPTS+=-mcpu=v8
. elif ${MACHINE_ARCH} == sparc64
COPTS+=-mcpu=ultrasparc
. elif ${MACHINE_ARCH} == powerpc
COPTS+=-mcpu=750
. elif ${MACHINE_ARCH} == alpha
COPTS+=-mcpu=21164a
. elif ${MACHINE_ARCH} == i386
COPTS+=-march=pentium2 -mcpu=pentium3
. endif

.endif  # BSD_PKG_MK

-----

I built current on a hypersparc system from a few days ago and it's
running just fine on a dual 135mhz Hypersparc system with -mcpu=v8.
OTOH, I don't see any huge speed increase...

I've, in the past, tried to build with -mcpu=hypersparc and not
been sucessful.  I can try again in a few days.

It's always possible that the machine description files for the hypersparc
have not been tested as much recently as the sparc ones.  This could mean 
that they don't quite work.  I'm also not sure that the hypersparc
gets any huge benefit from special scheduling.  It's not that complex.

cheers

bruce
