Tablegen PAT limitation?

Thanks.
Looking at the InOperandList, the rs1, rbase, etc. have register class prefixes, e.g. MGPR:$rs1. In the pattern they don’t have them. The error you saw (“rs1 must be an identifier”) was caused by tablegen being unable to match the rs1 in the pattern with any of the instruction operands.
Could you change the pattern to

NDS32 V3 backend
Hi all,
On behalf of Andes Technology Corp,
I am proposing a backend targeting the NDS32 V3 ISA.
NDS32 V3 ISA is a 16/32 bit mixed instruction set architecture that
developed By AndesTech.
You can find more information at the Andes website <http://www.andestech.com/>,
and reference AndeStar ISA Manual (V3 ISA) from document download page
<http://www.andestech.com/product.php?cls=9>.
