Re: Can't set architecture to m32c on m32c-elf-gdb.

Hello DJ,

Yes some series cores are already shipped it and some are still planning.
I didn't say R32C is same as M32C. But I think their register sets
and periherals are quite similar.
And Renesas says R32C is the high end model of M16C/M32C series, right?

I agree RX is completely different opcode/registers from M16C family.
("RX is a step up from R32C. " is similar to "SH-1/2 is a step up from H8")
So I have no view about RX supports on GNU chains.

Thanks,
