(legacy_value_to_register): Declare. (legacy_convert_register_p): Declare. * arch-utils.c (legacy_register_to_value): New function. (legacy_value_to_register): New function. (legacy_convert_register_p): New function. * gdbarch.sh (REGISTER_TO_VALUE): Define. (VALUE_TO_REGISTER): Define. (CONVERT_REGISTER_P): Define. * gdbarch.h, gdbarch.c: Regenerate. * valops.c (value_assign): Use CONVERT_REGISTER_P and VALUE_TO_REGISTER. * findvar.c (value_from_register): Use REGISTER_TO_VALUE and CONVERT_REGISTER_P. * gdbint.texinfo (Target Architecture Definition): Document REGISTER_TO_VALUE and VALUE_TO_REGISTER and CONVERT_REGISTER_P.
