[PATCH] D74436: Change clang option -ffp-model=precise to select ffp-contract=on

[Melanie Blower via Phabricator via cfe-commits]

mibintc added inline comments.


================
Comment at: clang/docs/UsersManual.rst:1501
 
-   * ``precise`` Disables optimizations that are not value-safe on floating-point data, although FP contraction (FMA) is enabled (``-ffp-contract=fast``).  This is the default behavior.
+   * ``precise`` Disables optimizations that are not value-safe on floating-point data, although FP contraction (FMA) is enabled (``-ffp-contract=on``).  This is the default behavior.
    * ``strict`` Enables ``-frounding-math`` and ``-ffp-exception-behavior=strict``, and disables contractions (FMA).  All of the ``-ffast-math`` enablements are disabled. Enables ``STDC FENV_ACCESS``: by default ``FENV_ACCESS`` is disabled. This option setting behaves as though ``#pragma STDC FENV_ACESS ON`` appeared at the top of the source file.

Good idea thanks. Can I do that in a separate patch?
