+/* 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.
