Description

Hi,
the `disassemble [/r|/m|/s]` command on gdb running against cfu code does not show the CUSTOM0/CFU instruction mnemonic but its machine code representation.

The toolchain is the August 2020 toolchain from freedom-tools.
GDB version is GNU gdb (SiFive GDB 9.1.0-2020.08.2) 9.1.
GCC version is 10.1.0 (SiFive GCC 10.1.0-2020.08.2).

Maybe related to #470.
