binutils/riscv: Register names in DWARF output
Adds a register name table for RiscV so that objdump and readelf can
both use better register names.
binutils/ChangeLog:
* dwarf.c (dwarf_regnames_riscv): New register name table.
(init_dwarf_regnames_riscv): New function.
(init_dwarf_regnames): Add call to initialise RiscV register
names.
* dwarf.h (init_dwarf_regnames_riscv): Declare.
* objdump.c (dump_dwarf): Add call to initialise RiscV register
names.
