eeh mentioned (or eluded to) a week or two ago that 32 bit kernels on
sparc64 offered more stability and compiler reliability.  i decided to
try it, but i've been unsuccessful in building GENERIC32 on a ultra2
with userland from sources of ~saturday.  the linker produces the
following

ld: warning: sparc:v9 architecture of input file `/sys/arch/sparc64/compile/NONPLUS/lib/compat/libcompat.a(tty_43.o)' is incompatible with sparc output

from

cc -Wa,-Av9a -mno-fpu -ffreestanding -g -O2 -Werror -Wall -Wno-main -Wpointer-arith -Wmissing-prototypes -Wstrict-prototypes -Wno-uninitialized -I../../../../../../lib/libkern/arch/sparc -Dsparc64 -I../../. -I../../../../../../arch -I../../../../../.. -nostdinc -D__ELF__ -DLKM -DMAXUSERS=64 -D_KERNEL -D_KERNEL_OPT    -c /home/src/sys/arch/sparc64/compile/NONPLUS/lib/kern/../../../../../../lib/libkern/strrchr.c

which generates v9 64bit object files

maple [33] file vers.o
vers.o: ELF 64-bit MSB relocatable, SPARC V9, version 1 (SYSV), not stripped

presumably -Wa,-Av9a needs to become -Wa,-Av8 or some such and perhaps
-msupersparc to tell it to produce sparcv8 object files?  or is cross-
compiling the only option right now?
