DEBUG_TYPE

#define DEBUG_TYPE   "firrtl-infer-domains"

Typedef Documentation

DomainValue

using DomainValue = mlir::TypedValue<DomainType>

Definition at line 60 of file InferDomains.cpp.

ExportTable

using ExportTable = DenseMap<DomainValue, TinyPtrVector<DomainValue> >

A map from domain IR values defined internal to the moduleOp, to ports that alias that domain.

These ports make the domain useable as associations of ports, and we say these are exporting ports.

Definition at line 279 of file InferDomains.cpp.

PendingExports

using PendingExports = llvm::MapVector<DomainValue, unsigned>

A map from local domains to an aliasing port index, where that port has not yet been created.

Eventually we will be exporting the domain value at the port index.

Definition at line 266 of file InferDomains.cpp.

PendingSolutions

using PendingSolutions = DenseMap<VariableTerm *, unsigned>

A map from unsolved variables to a port index, where that port has not yet been created.

Eventually we will have an input domain at the port index, which will be the solution to the recorded variable.

PortInsertions
