@ -2033,47 +2033,11 @@ This macro is defined, with value 1, if (and only if) the NeXT runtime
runtime is used, this macro is not defined, so that you can use this
macro to determine which runtime (NeXT or GNU) is being used.
@item __TARGET_BITS_ORDER__
This macro describes the target's bits order in a byte. Its value is
@code{__GCC_LITTLE_ENDIAN__} or @code{__GCC_BIG_ENDIAN__}.
@item __TARGET_BYTES_ORDER__
This macro is defined with value @code{__GCC_LITTLE_ENDIAN__} or
@code{__GCC_BIG_ENDIAN__} if the target's bytes order within a word
is little-endian or big-endian, respectively.
@item __TARGET_INT_WORDS_ORDER__
This macro is defined with value @code{__GCC_LITTLE_ENDIAN__} or
@code{__GCC_BIG_ENDIAN__} if the target's words order within a
multi-word integer datum is little-endian or big-endian, respectively.
@item __TARGET_FLOAT_WORDS_ORDER__
This macro is defined with value @code{__GCC_LITTLE_ENDIAN__} or
@code{__GCC_BIG_ENDIAN__} if the target's words order within a
multi-word floating-point datum is little-endian or big-endian, respectively.
@item __TARGET_FLOAT_FORMAT__
This macro is defined to describe the floating-point format used by the
target. It has value in the set comprised of:
@code{__UNKNOWN_FORMAT__}, @code{__IEEE_FORMAT__},
@code{__IBM_FORMAT__}, @code{__C4X_FORMAT__} and @code{__VAX_FORMAT__}.
@item __TARGET_USES_VAX_F_FLOAT__
This macro is defined with value 1 if the target uses the VAX F-format
for the single precision floating-point data type; else if has value 0.
@item __TARGET_USES_VAX_D_FLOAT__
@item __TARGET_USES_VAX_G_FLOAT__
These macros are always defined, with values 0 or 1. If
@code{__TARGET_FLOAT_FORMAT__} is @code{__VAX_FORMAT__} then they have
mutually exclusive values; else both have value 0. Non-zero
@code{__TARGET_USES_VAX_D_FLOAT__} means the target uses the VAX
D-format for the double precision floating-point data type; non-zero
@code{__TARGET_USES_VAX_G_FLOAT__} means the VAX G-format is used.
@item __TARGET_USES_VAX_H_FLOAT__
When non-zero, the target uses the VAX H-format for the extended
precision floating-point data type.
