Could not find a spill register

[Choi, Jang-Wook]

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.
