* defaults.h (REGNO_MODE_OK_FOR_BASE_P, REG_MODE_OK_FOR_BASE_P)
(MODE_BASE_REG_REG_CLASS, REGNO_MODE_OK_FOR_REG_BASE_P)
(REG_MODE_OK_FOR_REG_BASE_P): Provide default definitions.
* regclass.c (record_address_regs): Remove ifdef. Use
REG_MODE_OK_FOR_REG_BASE_P and MODE_BASE_REG_REG_CLASS.
* regrename.c (REG_MODE_OK_FOR_BASE_P): Remove unnecessary
definition.
(scan_rtx_address, replace_oldest_value_addr): Use
REG_MODE_OK_FOR_REG_BASE_P and MODE_BASE_REG_REG_CLASS.
* reload.c (REGNO_MODE_OK_FOR_BASE_P, REG_MODE_OK_FOR_BASE_P): Remove
unnecessary definitions.
(find_reloads_address_1): Support REG_MODE_OK_FOR_REG_BASE_P
and MODE_BASE_REG_REG_CLASS.
* config/arm/arm.h (MODE_BASE_REG_CLASS): Don't check reload_completed.
(MODE_BASE_REG_REG_CLASS): Define.
(REGNO_MODE_OK_FOR_REG_BASE_P): Define.
(REG_MODE_OK_FOR_REG_BASE_P): Define.
* doc/tm.texi (Register Classes): Document MODE_BASE_REG_REG_CLASS,
REG_MODE_OK_FOR_REG_BASE_P, and REGNO_MODE_OK_FOR_REG_BASE_P.
