// RUN: mlir-opt %s -affine-vectorizer-test -compose-maps 2>&1 | FileCheck %s
// For all these cases, the test traverses the `test_affine_map` ops and
// composes them in order one-by-one.
// For instance, the pseudo-sequence:
// "test_affine_map"() { affine_map = f } : () -> ()
// "test_affine_map"() { affine_map = g } : () -> ()
// "test_affine_map"() { affine_map = h } : () -> ()
// will produce the sequence of compositions: f, g(f), h(g(f)) and print the
// AffineMap h(g(f)), which is what FileCheck checks against.
