getLoadStoreNoWrapFlags()

LLVM::GEPNoWrapFlags getLoadStoreNoWrapFlags ( MemRefType type )

static

Returns GEP no-wrap flags for a memref load/store.

inbounds is always valid when indices are in-bounds per the memref spec. nuw requires every index*stride term to not unsigned-wrap, which holds iff all strides are statically non-negative. Negative strides would make the intermediate mul nuw overflow (e.g., idx * (-1 as u64) wraps for idx > 0).
