If you can’t find it in an ABI document… You might want to look at the GDB sources, which usually contains the code to handle various targets, probably in a file named “gdb/mips*tdep.h”.

The first 32 ones are the general purpose registers, but what about beyond that (e. g. lo/hi)? A link to an authoritative document would be most welcome. DWARF proper doesn't document this kind of thing, it's usually a part of the ABI, but the ABI handbook doesn't seem to mention DWARF. CAUTION: This email originated from outside of the organization.
