I know, but it is kind of a wallclock "speed" measurement.  I am pretty
sure my Alpha is faster than my VAX, since it compiles a kernel, or does
a make build faster.. :-)  Arguably it is doing things quite different
in the compiler on these two platforms.  So everyone "knows" the Alpha
is faster than the VAX, but how would I "know" when comparing my Celeron
to the Alpha?

Should '-mcpu=21164a' automatically pass the '-m21164a' to the assembler?
Or should the option really be "-mcpu=21164a -Wa,-m21164a" ??
