can someone do the same for RISC5?

Note that RISC5 [1], a project created as a target for Wirth's Oberon compilers, is a different project from RISC-V [2], a project created at Berkeley which became what is currently the most popular open source ISA.

It is funny that RISC-V International moved to Switzerland in 2020 so now both projects can be found in the same place.
