Ok, this contains all changes you suggested.
Andrew, I see you've already ARIed FLOAT_INFO. Do you want to add a
reference to the replacement?
R.
2002-02-06 Richard Earnshaw <rearnsha@arm.com>
* gdbarch.sh (PRINT_FLOAT_INFO): Add rule.
* gdbarch.c gdbarch.h: Regenerate.
* arch-utils.c (default_print_float_info): New function.
* arch-utils.h (default_print_float_info): Prototype it.
* infcmd.c (float_info): Call PRINT_FLOAT_INFO.
* doc/gdbint.texinfo (FLOAT_INFO): Mark as deprecated.
(PRINT_FLOAT_INFO): Document it.
* arm-tdep.c (arm_print_float_info): Renamed from arm_float_info.
* config/arm/tm-arm.h (FLOAT_INFO): Delete.
(PRINT_FLOAT_INFO): Define.
