[RFC] dereferenceable metadata
...oads as dead(in a Scalar IR form) and later that
prevented us to vectorize the operation, but before removing such
loads we could annotate the remaining loads in the series with
"dereferenceable" and later restore IR in a way that is suitable for
vectorization(see https://reviews.llvm.org/D35139 ). Also, please note
that’s the information that is lost when InstCombine kills the last
load in the series and there is no way to restore this information
later in following passes.
Thanks, Dinar.
