    • Add prototypes for static functions. · 546b63fb 
      (REGISTER_MOVE_COST, MEMORY_MOVE_COST): Include default definitions.
(reload): Count number of registers needed for insn using new reload type
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
registers; instead, put them back in the front of potential_reload_regs and
let them be allocated again.
(order_regs_for_reload): Don't restrict regs explicitly used if we have
SMALL_REGISTER_CLASSES defined.
(reload_as_needed): Don't need to deactivate optional reloads ever; if they
inherit, it must have been safe.
Call merge_assigned_reloads if SMALL_REGISTER_CLASSES.
(reload_reg_used_*): Refine our tracking of reload reg usage by defining more
of these HARD_REG_SETs.
(mark_reload_reg_in_use, reload_reg_free_p): Rework to use new method of
describing where a reload register is used.
(reload_reg_free_before_p, reload_reg_reaches_end_p): Likewise.
(allocate_reload_reg): Pass new reload descriptions.
(choose_reload_regs): Likewise.
Save and restore the new HARD_REG_SETs.
Remove now-redundant code to prevent conflicts.
(merge_assigned_reloads): New function.
(emit_reload_insns): Output each reload type into its own sequence, then
output the sequences in the proper order.
Put our output reloads after a CLOBBER made by find_reloads.
Pass ALL_REGS to find_equiv_regs; nothing special about GENERAL_REGS.
Don't use an old equivalence if doing so would be more expensive.
Clean up tracking of values still in reload regs using reload description
info to see if the reload reaches the end of the insn.
(gen_input_reload): Pass reload description and emit insns to end of current
sequence.
(inc_for_reload): Return void; no longer need INSN as operand.
Emit insns to end of current sequence.

    • (expand_expr, case MAX_EXPR/MIN_EXPR): If mode is multiword int, · f81497d9 
      use do_jump_by_parts_greater_rtx to compare efficiently.
(do_jump_by_parts_greater_rtx): New function.

    • (store_parm_decls): Use pedwarn for "promoted arg doesn't · 42f00318 
      match prototype" warning.

    • (expand_call): Always allocate TARGET in mode of result expression; · 5d2ac65e 
      VALREG might have been promoted.
Ensure TARGET is a REG when checking for promotion and verify that we
get back the mode we expect.
