MIPS objdump: Add `eabi32` and `eabi64` ABI options
Extend gpr and fpr register names with names suitable for both EABIs.
Heavily inspired by the EABI documenation written by Eric Christopher,
which can be read at
https://sourceware.org/legacy-ml/binutils/2003-06/msg00436.html
2025-02-15 Anghelo Carvajal <angheloalf95@gmail.com>
* mips-dis.c (mips_fpr_names_eabi32): New variable.
(mips_fpr_names_eabi64): New variable.
(mips_abi_choices): Add "eabi32" and "eabi64" options.
