The AST branch is merged into hcl-mlir branch, and implementation of hcl.max, hcl.min is added by this commit: afe4471

Test case added here:

heterocl/tests/test_reduce.py

Lines 5 to 44 in afe4471

def _test_maxpool(in_shape, out_shape, stride, kernel, test_dtype):
def max_pool(data):
h = hcl.reduce_axis(0, kernel)

return hcl.compute(
out_shape,
lambda hh, ww: hcl.max(
data[stride * hh + h, stride * ww + w], axis=[h, w], dtype=test_dtype
),
name="max_pool",
dtype=test_dtype,
)
A = hcl.placeholder(in_shape, "A", dtype=test_dtype)
s = hcl.create_schedule([A], max_pool)
f = hcl.build(s)
