buffer.assume.noalias

← buffer dialect

Refine an existing buffer root with an explicit noalias contract. The result preserves the same storage identity, extent, memory-space, alignment, and nullability facts, and marks the root identity as comparable for disjointness proofs. External buffer arguments do not gain this proof by default.
