URL: https://github.com/apache/incubator-tvm/pull/5693
Following up from conversation in #5689, this PR implements these rules for
lifting or embedding constants in Partitioned Functions:
- Pattern input ExprPattern(relay.const):
- Only match constant nodes that contain the same constant value and
embed them in the partitioned functions. In this case, the arguments of
partitioned functions will be reduced.
- Pattern input ConstantPattern:
- Only match constant nodes and embed them in the partitioned
functions. In this case, the arguments of partitioned functions will be reduced.
- Pattern input VarPattern('x'):
- Match only the var node with an optional specified name hint. In this
case, the arguments of partitioned function is fixed.
- Pattern input wildcard:
- Match anything. In this case, the arguments of partitioned function
is fixed.
- Pattern AltPattern:
- Match either lhs or rhs. depending on which side matched, recursively
apply this matching logic and embed constants appropriately based on the
contained pattern.
