Re: Questionn: mul functions for v850e

[unno-y at necat dot nec dot co dot jp]

Thank you for your reply.

I understood that this version gcc 2.95.2 did not support 
word mul functions of v850e.

I will tried -mv850e on gcc 2.96-xscale-010827 later, 
because I, not the system administrator,  can not try that right now.
