Member Function Documentation

collectConstants()

util::HashSet< rvsdg::SimpleNode * > jlm::hls::ConstantDistribution::collectConstants ( rvsdg::Region &  region )

staticprivate

Collects all constants within a region and recursively within its structural node's subregion.

Parameters

region

the region for which to collect constants

Returns

A set of constants.

Definition at line 107 of file distribute-constants.cpp.

collectOutputs()

util::HashSet< rvsdg::Output * > jlm::hls::ConstantDistribution::collectOutputs ( const rvsdg::SimpleNode &  constantNode )

staticprivate

For a given constant node constantNode, collect all gamma or theta node arguments/outputs where the constant node has users that are either another simple node or a lambda subregion result. The idea is that only outputs are of interest where there is a "real user" of a constant, and it is not just routed through a region.

Parameters

constantNode

The constant node for which to collect the outputs.

Returns

A set outputs that have "real users" of constantNode.

distributeConstantsInLambda()

void jlm::hls::ConstantDistribution::distributeConstantsInLambda ( const rvsdg::LambdaNode &  lambdaNode )

staticprivate

Distribute all constants within a lambda node.

Parameters

lambdaNode

The lambda node where the constants are distributed.

Definition at line 44 of file distribute-constants.cpp.

distributeConstantsInRootRegion()

void jlm::hls::ConstantDistribution::distributeConstantsInRootRegion ( rvsdg::Region &  region )

staticprivate

Traverse the root region as well as phi regions to find all lambda nodes where constants should be distributed.

Parameters

region

The region to traverse.

Definition at line 22 of file distribute-constants.cpp.

ConstantDistribution& jlm::hls::ConstantDistribution::operator= ( const ConstantDistribution &  )

Run()

void jlm::hls::ConstantDistribution::Run ( rvsdg::RvsdgModule &  module, util::StatisticsCollector &  statisticsCollector  )

overridevirtual

Perform RVSDG transformation.

Note

This method is expected to be called multiple times. An implementation is required to reset the objects' internal state to ensure correct behavior after every invocation.

Parameters

module	RVSDG module the transformation is performed on.
statisticsCollector	Statistics collector for collecting transformation statistics.

Implements jlm::rvsdg::Transformation.
