What about EV56s? I presume that the same config would be fine? And
as of what date is the above the case? With egcs-1.0 on redhat 4.2 I
found egcs producing code which ran about the same as gcc 2.7.2.1,
sometimes a little slower (-O2 -mcpu=21164). I tried to build
egcs-971225 & pre 1.0.1, but was unable to (because redhat 4.2's
binutils (v 2.7.0.2-4) was too old, I guess). Presumably, for the
same reason I couldn't use -mcpu=21164a with egcs-971225. How much of
a difference does -mcpu=21164 vs -mcpu=21164a make?
Thanks,
