[PATCH] D113107: Support of expression granularity for _Float16.

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Does GCC actually change the formal types of expressions to `float`, or is it doing this "no intermediate casts thing" as some sort of fp_contract-style custom emission of trees of expressions that involve `_Float16`?

In any case, doing operation-by-operation emulation seems like the right first approach rather than starting by doing the less conformant thing.
