New macros truncate toward zero to integer value but
return REAL_VALUE_TYPE.

fprintf if no REAL_ARITHMETIC, otherwise uses real.c for
binary to decimal conversion.  Used in ASM_OUTPUT_ macros.

(struct decompose): Move to before function declarations.
(secondary_memlocs_elim): One per operand, not per mode.
(get_secondary_mem): Accept and use reload description (opnum and type).
(push_reload): Accept and use new reload description instead of old NEEDED_FOR.
Define two new macros: MERGEABLE_RELOADS and MERGE_TO_OTHER.
Use these macros to see if reloads can be merged and how to do it.

description.

information.
If mode of insn is DImode, don't change it.
Refine the way we handle conflict with the return value register.
Don't try to account for needs already covered by previously spilled

let them be allocated again.
(order_regs_for_reload): Don't restrict regs explicitly used if we have
SMALL_REGISTER_CLASSES defined.

of these HARD_REG_SETs.

sequence.
