Detailed Description

This class provides information about the result of a visit.

After walking all the users (recursively) of a pointer, the basic infrastructure records some commonly useful information such as escape analysis and whether the visit completed or aborted early.

◆ getAbortingInst()

Instruction* llvm::detail::PtrUseVisitorBase::PtrInfo::getAbortingInst ( ) const
inline

Get the instruction causing the visit to abort.

Returns
a pointer to the instruction causing the abort if one is available; otherwise returns null.

◆ getEscapingInst()

Instruction* llvm::detail::PtrUseVisitorBase::PtrInfo::getEscapingInst ( ) const
inline

Get the instruction causing the pointer to escape.

Returns
a pointer to the instruction which escapes the pointer if one is available; otherwise returns null.

◆ isEscaped()

bool llvm::detail::PtrUseVisitorBase::PtrInfo::isEscaped ( ) const
inline

Is the pointer escaped at some point?

◆ reset()

void llvm::detail::PtrUseVisitorBase::PtrInfo::reset ( )
inline

◆ setAborted()

void llvm::detail::PtrUseVisitorBase::PtrInfo::setAborted ( Instruction I = nullptr)
inline

Mark the visit as aborted.

Intended for use in a void return.

Parameters
IThe instruction which caused the visit to abort, if available.

◆ setEscaped()

void llvm::detail::PtrUseVisitorBase::PtrInfo::setEscaped ( Instruction I = nullptr)
inline

◆ setEscapedAndAborted()

void llvm::detail::PtrUseVisitorBase::PtrInfo::setEscapedAndAborted ( Instruction I = nullptr)
inline

Mark the pointer as escaped, and the visit as aborted.

Intended for use in a void return.

Parameters
IThe instruction which both escapes the pointer and aborts the visit, if available.
