Hi all,
I am wondering why arch/powerpc/cpu/mpc83xx/config.mk sets -msoft-float for all
ppc 83xx processors. This is valid e.g. for MPC8321 but e.g. the MPC8360 has a
hardware floating point unit. Shouldn't the config.mk file distinguish between
different 83xx processors to set this flag only for those which don't have a FPU?
Best regards
Holger Brunck

This has been discussed to death here before. The short answer is
-msoft-float is correct. The long answer is in the list archives. The
last major debate on the topic was a month or two ago.
