@@ -3197,41 +3197,6 @@ The pragma can also be used with ``off`` which turns FP contraction off for a
section of the code. This can be useful when fast contraction is otherwise
enabled for the translation unit with the ``-ffp-contract=fast`` flag.
-The ``#pragma float_control`` pragma allows precise floating-point
-semantics and floating-point exception behavior to be specified
-for a section of the source code. This pragma can only appear at file scope or
-at the start of a compound statement (excluding comments). When using within a
-compound statement, the pragma is active within the scope of the compound
-statement. This pragma is modeled after a Microsoft pragma with the
-same spelling and syntax. For pragmas specified at file scope, a stack
-is supported so that the ``pragma float_control`` settings can be pushed or popped.
-
-When ``pragma float_control(precise, on)`` is enabled, the section of code
-governed by the pragma uses precise floating point semantics, effectively
-``-ffast-math`` is disabled and ``-ffp-contract=on``
-(fused multiply add) is enabled.
-
-When ``pragma float_control(except, on)`` is enabled, the section of code governed
-by the pragma behaves as though the command-line option
-``-ffp-exception-behavior=strict`` is enabled,
-when ``pragma float_control(precise, off)`` is enabled, the section of code
-governed by the pragma behaves as though the command-line option
-``-ffp-exception-behavior=ignore`` is enabled.
-
-The full syntax this pragma supports is
-``float_control(except|precise, on|off [, push])`` and
-``float_control(push|pop)``.
-The ``push`` and ``pop`` forms, including using ``push`` as the optional
-third argument, can only occur at file scope.
