connectLeafsTo()

static void connectLeafsTo ( ImplicitLocOpBuilder &  builder, Value  bundle, Value  value  )

static

Drive a value to all leafs of the input aggregate value.

This only makes sense when all leaf values have the same type, since the same value will be connected to each leaf. This does not work for aggregates with flip types.

Definition at line 150 of file LowerCHIRRTL.cpp.

References circt::firrtl::emitConnect(), and forEachLeaf().

forEachLeaf()

static void forEachLeaf ( ImplicitLocOpBuilder &  builder, Value  value, llvm::function_ref< void(Value)>  func  )

static

Performs the callback for each leaf element of a value.

This will create any subindex and subfield operations needed to access the leaf values of the aggregate value.

memDirAttrToPortKind()

static MemOp::PortKind memDirAttrToPortKind ( MemDirAttr  direction )

static

Converts a CHIRRTL memory port direction to a MemoryOp port type.

The biggest difference is that there is no match for the Infer port type.
