Classes
struct	circt::llhd::ConstProjectionRange
	Portion of a signal selected by a projection, with a statically known offset and width in bits. More...
struct	circt::llhd::DynProjectionRange
	Portion of a signal selected by a projection with a dynamic index. More...

Namespaces
namespace	circt

Typedefs
using	circt::llhd::ProjectionRange = std::variant<ConstProjectionRange, DynProjectionRange>
	Portion of the signal operand that is selected by a projection.

Functions
bool	circt::llhd::isDynamic (const ProjectionRange &range)
	Helper to check if a projection range is dynamic or not.
Type	circt::llhd::getStoredType (Value slot)
	Return the type stored in a signal or projection.
bool	circt::llhd::isProjection (const Operation *op)
	Check if an op is one of the supported projection types.
std::optional< ProjectionRange >	circt::llhd::getProjectionRange (Operation *op)
	Calculate a projection's range.
bool	circt::llhd::isProvablyDisjoint (const ProjectionRange &a, const ProjectionRange &b)
	Check whether two projections provably describe disjoint storage.
Operation *	circt::llhd::getRootSignal (Value sig)
	Given a signal or a projection, walk back the projection chain until you find the root signal declaration.
std::pair< Operation *, std::optional< ProjectionRange > >	circt::llhd::getRootSignalAndRange (Value sig)
	Given a signal or a projection, find the root signal declaration by traversing the projection chain.
