[LLVMdev] Fixed register operations

[Carlos Sánchez de La Lama]

Hi all,

is it possible to define an instruction as always having a certain  
register as operand in XXXInstrInfo.td? I know I can do it defining a  
single-register register class, but I need that register also to be on  
a broader class for other operations (and it is not possible for a reg  
to be in several classes AFAIU).

Thanks!

Carlos
