+@defmac HONOR_REG_ALLOC_ORDER
+Normally, IRA tries to estimate the costs for saving a register in the
+prologue and restoring it in the epilogue.  This discourages it from
+using call-saved registers.  If a machine wants to ensure that IRA
+allocates registers in the order given by REG_ALLOC_ORDER even if some

 In some case register allocation order is not enough for the
 Integrated Register Allocator (@acronym{IRA}) to generate a good code.
