-@defmac CLASS_LIKELY_SPILLED_P (@var{class})
-A C expression whose value is nonzero if pseudos that have been assigned
-to registers of class @var{class} would likely be spilled because
-registers of @var{class} are needed for spill registers.

-The default value of this macro returns 1 if @var{class} has exactly one
-register and zero otherwise.  On most machines, this default should be
-used.  Only define this macro to some other expression if pseudos
-allocated by @file{local-alloc.c} end up in memory because their hard
-registers were needed for spill registers.  If this macro returns nonzero
-for those classes, those pseudos will only be allocated by
-@file{global.c}, which knows how to reallocate the pseudo to another
-register.  If there would not be another register available for
-reallocation, you should not change the definition of this macro since
-the only effect of such a definition would be to slow down register

 @defmac CLASS_MAX_NREGS (@var{class}, @var{mode})
 A C expression for the maximum number of consecutive registers
 of class @var{class} needed to hold a value of mode @var{mode}.
