Detailed Description

This class keeps track of modules and interfaces that need to be renamed, as well as module ports, parameters, declarations and verif labels that need to be renamed.

This can happen either due to conflicts between them or due to a conflict with a Verilog keyword.

Once constructed, this is immutable.

GlobalNameResolver() [1/2]

GlobalNameResolver::GlobalNameResolver	(	mlir::ModuleOp	topLevel,
		const LoweringOptions &	options
	)

Construct a GlobalNameResolver and perform name legalization of the module/interfaces, port/parameter and declaration names.

Construct a GlobalNameResolver and do the initial scan to populate and unique the module/interfaces and port/parameter names.
