@end deftypefn
@defmac TARGET_FLOAT_FORMAT
A code distinguishing the floating point format of the target machine.
There are two defined values:
@ftable @code
@item IEEE_FLOAT_FORMAT
This code indicates IEEE floating point. It is the default; there is no
need to define @code{TARGET_FLOAT_FORMAT} when the format is IEEE@.
@item VAX_FLOAT_FORMAT
This code indicates the ``F float'' (for @code{float}) and ``D float''
or ``G float'' formats (for @code{double}) used on the VAX and PDP-11@.
@end ftable
If your target uses a floating point format other than these, you must
define a new @var{name}_FLOAT_FORMAT code for it, and add support for
it to @file{real.c}.
The ordering of the component words of floating point values stored in
memory is controlled by @code{FLOAT_WORDS_BIG_ENDIAN}.
@end defmac
@defmac ROUND_TOWARDS_ZERO
If defined, this macro should be true if the prevailing rounding
mode is towards zero.
