Could not find a spill register

["Choi, Jang-Wook" <choijo at adc dot co dot kr>]

Hello, everyone.

I'm building a cross compiler to new 64bit processor using gcc.

I made new machine dependent files.

 

When I build it, "Could not find spill register" error occurrs.

Someone told me to give change to FIXED_REGISTER macro in tm.h.

But same error occurres.

 

Does someone know why this error happens?

Thank you.
