pa.h (FIXED_REGISTERS): %r2 is no longer fixed.
* pa.h (FIXED_REGISTERS): %r2 is no longer fixed.
(REG_ALLOC_ORDER): Treat %r2 as a caller-saved allocatable
register. %r30 is fixed and therefore a "special" register.
%fr22-%fr31 are caller-saved, so allocate them before the
callee-saved 1.1 fp registers. Allocate fp registers before
general registers. Fix typo for register 79.
* pa.h (FIRST_PSEUDO_REGISTER): Update to take into account
registers which are no longer known to the compiler.
(FIXED_REGISTERS): Likewise.
(CALL_USED_REGISTERS): Likewise.
(HARD_REGNO_NREGS): Likewise.
(HARD_REGNO_MODE_OK): Likewise.
(REGNO_REG_CLASS): Likewise.
(FUNCTION_VALUE): Likewise.
(LIBCALL_VALUE): Likewise.
(FUNCTION_VALUE_REGNO_P): Likewise.
(FUNCTION_ARG_REGNO_P): Likewise.
(FUNCTION_ARG): Likewise.
(REGNO_OK_FOR_FP_P): Likewise.
(REGISTER_NAMES): Likewise.
(REG_CLASS_CONTENTS): Likewise. Add %r1 to GENERAL_OR_FP_REGS
and GENERAL_OR_SNAKE_FP_REGS.
(REG_ALLOC_ORDER): Likewise. Document and make allocation order
"regular" across 1.0 and 1.1 cpus.
