Hi,
I am trying to implement a simple pass that merges a certain pattern into a
single "normalize" op. I use the **register_pattern_table** which I understand
is support to register the pass.
def make_pattern():
data = wildcard()
data2 = wildcard()
data3 = wildcard()
copy_op = is_op("copy")(data)
reshape1_op = is_op("reshape")(data2)
substract_op = is_op("subtract")(copy_op, reshape1_op)
reshape2_op = is_op("reshape")(data3)
divide_op = is_op("reshape")(substract_op, reshape2_op)
return divide_op
@register_pattern_table
def normalize_pattern():
normalize_pat = ("normalize", make_pattern())
normalize_patterns = [normalize_pat]
return normalize_patterns
I import this code in my test but nothing happens. the code is not called. what
am I missing?
It will really help if you could show me a tutorial or example of adding a
pattern matching pass end-to-end.
