inlinestatic

Walk the given IST operation and invoke the callback for all encountered inner symbols.

This variant allows callbacks that return LogicalResult OR void, and wraps the underlying implementation.

◆ walkSymbols() [2/2]

LogicalResult circt::hw::InnerSymbolTable::walkSymbols	(	Operation *	op,

static

Walk the given IST operation and invoke the callback for all encountered inner symbols.

This variant is the underlying implementation. If callback returns failure, the walk is aborted and failure is returned. A successful walk with no failures returns success.
