◆ collectModels()

mlir::LogicalResult circt::arc::collectModels	(	mlir::ModuleOp	module,
		llvm::SmallVector< ModelInfo > &	models )

Collects information about all Arc models in the provided module, and adds it to models.

◆ collectStates()

mlir::LogicalResult circt::arc::collectStates	(	mlir::Value	storage,
		unsigned	offset,
		llvm::SmallVector< StateInfo > &	states )

Collects information about states within the provided Arc model storage storage, assuming default offset, and adds it to states.

◆ computeLLVMBitWidth()

std::optional< uint64_t > circt::arc::computeLLVMBitWidth ( mlir::Type type )

Compute the bit width a type will have when allocated as part of the simulator's storage.

This includes any padding and alignment that may be necessary once the type has been mapped to LLVM. The idea is for this function to be conservative, such that we provide sufficient storage bytes for any type.
