[PATCH] D146148: Float_t and double_t types shouldn't be modified by #pragma clang fp eval_method

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

The user isn't modifying the `float_t` type definition, they're using it.  I think the diagnostic should say something like `cannot use type 'float_t' within '#pragma clang fp eval_method'; type is set according to the default eval method for the translation unit`.

Is there any way we can infer an attribute for these typedefs when they're declared, then diagnose it in `DiagnoseUseOfDecl`?  Some sort of "available_only_in_default_eval_method" attribute?
