+@defmac REGMODE_NATURAL_SIZE (@var{mode})
+Define this macro if the natural size of registers that hold values
+of mode @var{mode} is not the word size. It is a C expression that
+should give the natural size in bytes for the specified mode. It is
+used by the register allocator to try to optimize its results. This
+happens for example on SPARC 64-bit where the natural size of
+floating-point registers is still 32-bit.

@defmac HARD_REGNO_MODE_OK (@var{regno}, @var{mode})
A C expression that is nonzero if it is permissible to store a value
of mode @var{mode} in hard register number @var{regno} (or in several
