createZeroValue() [1/2]

static Value createZeroValue ( ImplicitLocOpBuilder &  builder, FIRRTLBaseType  type  )

static

Construct a null value of the given type using the given builder.

getResetName()

static StringAttr getResetName ( Value  reset )

static

Return the name of a reset.

The reset value must either be a module port or a wire/node operation.

Definition at line 64 of file FullReset.cpp.

References getResetNameAndModule().

getResetNameAndModule()

static std::pair< StringAttr, FModuleOp > getResetNameAndModule ( Value  reset )

static

Return the name and parent module of a reset.

The reset value must either be a module port or a wire/node operation.

insertResetMux()

static bool insertResetMux ( ImplicitLocOpBuilder &  builder, Value  target, Value  reset, Value  resetValue  )

static

Helper function that inserts reset multiplexer into all ConnectOps with the given target.

Looks through SubfieldOp, SubindexOp, and SubaccessOp, and inserts multiplexers into connects to these subaccesses as well. Modifies the insertion location of the builder. Returns true if the resetValue was used in any way, false otherwise.
