By the way, the MXL is const now in recently updated RISC-Vspecification.
Oh yes?

Yes.  In 1.13 privileged specification about MISA CSR:

"The MXL field is read-only. If misa is nonzero, the MXL field indicatesthe effective XLEN in M-mode, a

constant termed MXLEN."

Then perhaps we should rename misa_mxl_max to misa_mxl.


I will mark this on my todo list.

Thanks,
