@ -2389,6 +2389,40 @@ These macros are defined with value 1 if the backend supports the
the include file @file{math.h} can define the macros
@code{FP_FAST_FMA}, @code{FP_FAST_FMAF}, and @code{FP_FAST_FMAL}
for compatibility with the 1999 C standard.
@item __GCC_IEC_559
This macro is defined to indicate the intended level of support for
IEEE 754 (IEC 60559) floating-point arithmetic. It expands to a
nonnegative integer value. If 0, it indicates that the combination of
the compiler configuration and the command-line options is not
intended to support IEEE 754 arithmetic for @code{float} and
@code{double} as defined in C99 and C11 Annex F (for example, that the
standard rounding modes and exceptions are not supported, or that
optimizations are enabled that conflict with IEEE 754 semantics). If
1, it indicates that IEEE 754 arithmetic is intended to be supported;
this does not mean that all relevant language features are supported
by GCC. If 2 or more, it additionally indicates support for IEEE
754-2008 (in particular, that the binary encodings for quiet and
signaling NaNs are as specified in IEEE 754-2008).
This macro does not indicate the default state of command-line options
that control optimizations that C99 and C11 permit to be controlled by
standard pragmas, where those standards do not require a particular
default state. It does not indicate whether optimizations respect
signaling NaN semantics (the macro for that is
@code{__SUPPORT_SNAN__}). It does not indicate support for decimal
floating point or the IEEE 754 binary16 and binary128 types.
@item __GCC_IEC_559_COMPLEX
This macro is defined to indicate the intended level of support for
IEEE 754 (IEC 60559) floating-point arithmetic for complex numbers, as
defined in C99 and C11 Annex G. It expands to a nonnegative integer
value. If 0, it indicates that the combination of the compiler
configuration and the command-line options is not intended to support
Annex G requirements (for example, because @option{-fcx-limited-range}
was used). If 1 or more, it indicates that it is intended to support
those requirements; this does not mean that all relevant language
features are supported by GCC.
