    Hello everyone,

While using the following llvm-tblgen command to generate the inc files based on the td files in the llvm-capstone repo https://github.com/capstone-engine/llvm-capstone 

`/home/projects/capstone-playground/capstone/suite/auto-sync/llvm-capstone/build/bin/llvm-tblgen --printerLang=CCS --gen-asm-matcher -I /home/projects/capstone-playground/capstone/suite/auto-sync/llvm-capstone/llvm/include -I /home/projects/capstone-playground/capstone/suite/auto-sync/llvm-capstone/llvm/lib/Target/RISCV /home/projects/capstone-playground/capstone/suite/auto-sync/llvm-capstone/llvm/lib/Target/RISCV/RISCV.td` 

This is the .tf file that was used https://github.com/capstone-engine/llvm-capstone/blob/auto-sync/llvm/lib/Target/RISCV/RISCV.td 

I got the following error:

Apparently something went wrong in the function `getEnumName `when it is called from the fucntion `getOperandDataTypes `

Any idea what could have gone wrong? Thanks in advance!
