Detailed Description

A debug info location.

This class is a wrapper around a tracking reference to an DILocation pointer.

To avoid extra includes, DebugLoc doubles the DILocation API with a one based on relatively opaque MDNode pointers.

default

Referenced by getFnDebugLoc().

◆ DebugLoc() [2/3]

DebugLoc::DebugLoc ( const DILocation * L )

Construct from an DILocation.

Definition at line 17 of file DebugLoc.cpp.

◆ DebugLoc() [3/3]

DebugLoc::DebugLoc ( const MDNode * N )

explicit

Construct from an MDNode.

Note: if N is not an DILocation, a verifier check will fail, and accessors will crash. However, construction from other nodes is supported in order to handle forward references when reading textual IR.

DebugLoc DebugLoc::appendInlinedAt	(	const DebugLoc &	DL,

static

Rebuild the entire inlined-at chain for this instruction so that the top of the chain now is inlined-at the new call site.

Parameters

InlinedAt The new outermost inlined-at in the chain.

◆ getFnDebugLoc()

DebugLoc DebugLoc::getFnDebugLoc ( ) const

Find the debug info location for the start of the function.

Walk up the scope chain of given debug loc and find line number info for the function.

FIXME: Remove this. Users should use DILocation/DILocalScope API to find the subprogram, and then DILocation::get().

llvm::DebugLoc::operator bool ( ) const

Check for null.

Check for null in a way that is safe with broken debug info. Unlike the conversion to DILocation, this doesn't require that Loc is of the right type. Important for cases like llvm::StripDebugInfo() and Instruction::hasMetadata().
