--- Comment #13 from Adam Nemet <anemet at apple.com> ---
This was added in several commits to the IR and SDAG (e.g. r298939). Clang also
gained a new pragma (#pragma clang fp contract(on/off/fast)) for fine-grained
control beyond -ffp-contract=fast.

This flag is not yet exposed in MIR.  File PR33713 for that.
