[PATCH] D68231: [SLC] Allow llvm.pow(x,2.0) -> x*x etc even if no pow() lib func

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

The patch description is only stating the previous status-quo as a fact,
but gives no reasoning as to why it should change, why it is legal/okay to change it.

Is this really sane?
Can we really invent calls to non-builtin (aka potentially user-provided/overriden) C math function?
