jlm::llvm::TracedPointerOrigin Struct Reference

#include <Trace.hpp>

Collaboration diagram for jlm::llvm::TracedPointerOrigin:

Public Member Functions
std::optional< int64_t >	getOffsetInBytes () const noexcept

Public Attributes
const rvsdg::Output *	BasePointer = nullptr
std::optional< std::vector< GetElementPtrOperation::Constant > >	gepConstants {}

Detailed Description

Represents the result of tracing a pointer p to some origin, as a traced base pointer value plus the encountered statically known GetElementPtrOperation offsets.

If the offsets are present, that means p = base pointer + offsets

If the offsets are not present, that means p = base pointer + [unknown offset]
