[PATCH] D15120: Add support for __float128 type to be used by targets that support it

[John McCall via cfe-commits]

rjmccall added a comment.

I think it's not unlikely that float128_t will see future standardization (as an optional extension, of course), and it would be strange for an operation between two types to not consistently yield the type of higher rank.

I could see an argument that we should not treat float128_t as a distinct type from long double on targets where they have the same implementation.  That might avoid the need for special-case manglings.
