You may want to use llvm.minnum directly (providing the semantics are indeed equivalent). Otherwise it will need fastmath to fuse these together, which isn't the same as the original intrinsic.

Fix non-predicated floats.

Thanks. I'm happy if simon does not have any extra comments.

I do, but only an indentation quibble.


It's a ludicrously minor nitpick, but if you could indent this NameOverride much further left, to indicate that it's a second base class alongside Intrinsic and not part of the template parameters of Intrinsic, that would be clearer. Same for the one below.

Address whitespace nit.

Nit terminated with extreme prejudice.
