Combine the metadata of two instructions so that K can replace J. This specifically handles the case of CSE‐like transformations. Some metadata can only be kept if K dominates J. For this to be correct, K cannot be hoisted.

Synopsis

Declared in <llvm/Transforms/Utils/Local.h>

void
combineMetadataForCSE(
    Instruction* K,
    Instruction const* J,
    bool DoesKMove);

Description

Unknown metadata is removed.
