[9fans] plan 9 ports churn

[Russ Cox]

There's a lot of new stuff in the Plan 9 ports tarball/CVS
but the downside is that I don't know how well it
builds on systems other than FreeBSD and Linux.
(Actually going through all the motions takes me 
a full day, and I just can't justify doing it again so soon.)

If you're not in the mood for slightly untested stuff,
don't update for a while.

plan9-20040424.tar.gz does not build ''out-of-the-box'' on solaris-2.8

the file plan9/src/libmach/SunOS.c does not exist. tentative fix by 
copying Darwin.c to SunOS.c

twice i get the following ''for loop'' in the ''install'' script output:

for i in port sun4u
do
	(cd $i; mk <something>)
done
<commands>
sh: sun4u: does not exist

there are 3 places in the directory structure where this might happen:

./src/libmp
./src/libsec
./acid

in all 3 places the ''sun4u'' makes no sense but replace it with 
''sparc'' and things seems logical. to achive this replace ''uname -m'' 
with ''uname -p'' in plan9/src/mkhdr:2 .

after doing that it is also neccessary to rename all the files with 
sun4u in their names:

cp ./plan9/src/libthread/asm-SunOS-sun4u.s 
./plan9/src/libthread/asm-SunOS-sparc.s
cp ./plan9/src/libthread/sun4u.c ./plan9/src/libthread/sparc.c
cp ./plan9/src/lib9/getcallerpc-sun4u.s ./plan9/src/lib9/getcallerpc-sparc.s
cp ./plan9/src/lib9/tas-sun4u.s ./plan9/src/lib9/tas-sparc.s
cp ./plan9/unix/make/Make.SunOS-sun4u ./plan9/unix/make/Make.SunOS-sparc
cp ./plan9/unix/make/Make.SunOS-sun4u-cc 
./plan9/unix/make/Make.SunOS-sparc-cc
cp ./plan9/unix/make/Make.SunOS-sun4u-gcc 
./plan9/unix/make/Make.SunOS-sparc-gcc


3
i get a loader error, when plan9/src/libthread/sched.c calls 
_threadstacklimit() which is in plan9/src/libthread/386.c, but not in 
plan9/src/libthread/sparc.c. ''solved'' by adding empty functions to 
plan9/src/libthread/sparc.c

void
_threadinswitch(int enter)
{
	USED(enter);
}

void
_threadstacklimit(void *addr)
{
	USED(addr);

}

i have a suggestion on how to make ''9c'' perform as intended on sunos, 
with sun-cc. the ''uname -p'' change is only there to be consistent with 
the changes to $OBJTYPE that i have already made in other places. if 
sun4u is better value than sparc this change should be ignored:
