- Subject: [RFA] remove ALPHA_FP_REGNUM
Even worse than other ports, this was some bogus non-architectural
register that sort of corresponds to the dwarf2 CFA concept, but
hasn't actually been set to anything useful in who knows how long.
So I've removed it entirely. Ok?
r~
* alpha-tdep.h (ALPHA_NUM_REGS): Decrement.
(ALPHA_FP_REGNUM): Remove.
(ALPHA_UNIQUE_REGNUM): Decrement.
* alpha-tdep.c (alpha_register_name): Remove vfp entry.
(alpha_cannot_fetch_register): Remove ALPHA_FP_REGNUM.
(alpha_cannot_store_register): Likewise.
* alphabsd-nat.c (fetch_inferior_registers): Don't set FP_REGNUM.
* alpha-nat.c (supply_gregset): Likewise.
* alphanbsd-tdep.c (fetch_core_registers): Likewise.
