[cfe-commits] [PATCH 3/3] Make fp-contract=fast default for Freescale vendor

[Hal Finkel]

Lang, et al.,

Do you (or anyone else) have an opinion on this? Do we want to
introduce vendor-specific defaults for this? Should we wait until
contraction is fully implemented in clang and let them test the
differential performance (and what's the status on that)?

Thanks again,
Hal
