   And "-mcpu=supersparc" is deprecated.

what makes you say that?  certainly, given my current reading of
gcc-current/gcc/config/sparc/sparc.c, "-mcpu=v8" means to enable
v8 "cpu" (ie, instructions), and v8 "tune" ("-mtune=v8" only
enables tuning however), where as "-mcpu=supersparc" gives you
supersparc versions of those.  the same exists for all these
strings:

	v7
	cypress
	v8
	supersparc
	sparclite
	f930
	f934
	hypersparc
	sparclite86x
	sparclet
	tsc701
	v9
	ultrasparc

while i haven't read exactly what the different between say
PROCESSOR_V8 and PROCESSOR_SUPERSPARC, they would appear to
be different on the surface.



   However, "-mcpu=v8 -mtune=supersparc" seems to work.

i imagine this is only different from "-mcpu=supersparc" if
supersparc has any instruction differences to plain "v8"
(doubtful?  but i'm not sure offhand.)
