Herald added a project: clang.

Pragma 'clang fp' is extended to support two new options, 'rounding' and
'exceptions'. They allow to specifying floating point environment more
precisely than '#pragma STDC FENV_ACCESS' does. Syntax of the pragma is
described in LanguageExtensions.rst.
The primary goal of this change is to facilitate development of support
for floating point operations in non-default or dynamic environment.
