Just as a general comment, the RISC-V psabi currently only specifies the
dwarf2 register numbers, which the compiler obviously needs.  Otherwise, it
doesn't try to document anything gdb related, as it has been mainly
assembler/linker/compiler folk contributing to it.  At some point we might
need some gdb related documentation.  Some of the changes here potentially
affect llvm/lldb and the FreeBSD folks, and they may not be reading GNU
mailing lists.
