Invalidate all interleave groups.

Synopsis

Declared in <llvm/Analysis/VectorUtils.h>

bool
invalidateGroups();

Description

Used, for example, when all blocks in the loop will be predicated contrary to the original assumption. Although we currently prevent group formation for predicated accesses, we may be able to relax this limitation in the future once we handle more complicated blocks. Returns true if any groups were invalidated.

Return Value

True if any interleave groups were invalidated.
