#ifndef __IEEE_BIG_ENDIAN
#ifndef __IEEE_LITTLE_ENDIAN
/* This file can define macros to choose variations of the IEEE float
format:
_FLT_LARGEST_EXPONENT_IS_NORMAL
Defined if the float format uses the largest exponent for finite
numbers rather than NaN and infinity representations. Such a
format cannot represent NaNs or infinities at all, but it's FLT_MAX
is twice the IEEE value.
_FLT_NO_DENORMALS
Defined if the float format does not support IEEE denormals. Every
float with a zero exponent is taken to be a zero representation.
??? At the moment, there are no equivalent macros above for doubles and
the macros are not fully supported by --enable-newlib-hw-fp.
__IEEE_BIG_ENDIAN
Defined if the float format is big endian. This is mutually exclusive
with __IEEE_LITTLE_ENDIAN.
__IEEE_LITTLE_ENDIAN
Defined if the float format is little endian. This is mutually exclusive
with __IEEE_BIG_ENDIAN.
Note that one of __IEEE_BIG_ENDIAN or __IEEE_LITTLE_ENDIAN must be specified for a
platform or error will occur.
__IEEE_BYTES_LITTLE_ENDIAN
This flag is used in conjunction with __IEEE_BIG_ENDIAN to describe a situation
whereby multiple words of an IEEE floating point are in big endian order, but the
words themselves are little endian with respect to the bytes.
_DOUBLE_IS_32BITS
This is used on platforms that support double by using the 32-bit IEEE
float type.
_FLOAT_ARG
This represents what type a float arg is passed as. It is used when the type is
not promoted to double.
__OBSOLETE_MATH_DEFAULT
Default value for __OBSOLETE_MATH if that's not set by the user.
It should be set here based on predefined feature macros.
__OBSOLETE_MATH
If set to 1 then some new math code will be disabled and older libm
code will be used instead. This is necessary because the new math
code does not support all targets, it assumes that the toolchain has
ISO C99 support (hexfloat literals, standard fenv semantics), the
target has IEEE-754 conforming binary32 float and binary64 double
(not mixed endian) representation, standard SNaN representation,
double and single precision arithmetics has similar latency and it
has no legacy SVID matherr support, only POSIX errno and fenv
exception based error handling.
