This graph shows which files directly or indirectly include this file:

Go to the source code of this file.

Classes
class	llvm::DebugInfoFinder
	Utility to find all debug info in a module. More...
class	llvm::at::DbgAssignIt
	High level: this is an iterator for llvm.dbg.assign intrinsics. More...
struct	llvm::at::VarRecord
	Helper struct for trackAssignments, below. More...
struct	llvm::at::AssignmentInfo
	Describes properties of a store that has a static size and offset into a some base storage. More...
class	llvm::AssignmentTrackingPass
	Convert @llvm.dbg.declare intrinsics into sets of @llvm.dbg.assign intrinsics by treating stores to the dbg.declare'd address as assignments to the variable. More...

Namespaces
	llvm
	This is an optimization pass for GlobalISel generic memory operations.
	llvm::at
	Assignment Tracking (at).

Typedefs
using	llvm::at::AssignmentInstRange = iterator_range< SmallVectorImpl< Instruction * >::iterator >
	A range of instructions. More...
using	llvm::at::AssignmentMarkerRange = iterator_range< DbgAssignIt >
	A range of llvm.dbg.assign intrinsics. More...
using	llvm::at::StorageToVarsMap = DenseMap< const AllocaInst *, SmallSet< VarRecord, 2 > >
	Map of backing storage to a set of variables that are stored to it. More...

Functions
TinyPtrVector< DbgVariableIntrinsic * >	llvm::FindDbgAddrUses (Value *V)
	Finds all intrinsics declaring local variables as living in the memory that 'V' points to. More...
TinyPtrVector< DbgDeclareInst * >	llvm::FindDbgDeclareUses (Value *V)
	Like FindDbgAddrUses, but only returns dbg.declare intrinsics, not dbg.addr. More...
void	llvm::findDbgValues (SmallVectorImpl< DbgValueInst * > &DbgValues, Value *V)
	Finds the llvm.dbg.value intrinsics describing a value. More...
void	llvm::findDbgUsers (SmallVectorImpl< DbgVariableIntrinsic * > &DbgInsts, Value *V)
	Finds the debug info intrinsics describing a value. More...
DISubprogram *	llvm::getDISubprogram (const MDNode *Scope)
	Find subprogram that is enclosing this scope. More...
DebugLoc	llvm::getDebugValueLoc (DbgVariableIntrinsic *DII)
	Produce a DebugLoc to use for each dbg.declare that is promoted to a dbg.value. More...
bool	llvm::StripDebugInfo (Module &M)
	Strip debug info in the module if it exists. More...
bool	llvm::stripDebugInfo (Function &F)
bool	llvm::stripNonLineTableDebugInfo (Module &M)
	Downgrade the debug info in a module to contain only line table information. More...
void	llvm::updateLoopMetadataDebugLocations (Instruction &I, function_ref< Metadata *(Metadata *)> Updater)
	Update the debug locations contained within the MD_loop metadata attached to the instruction I, if one exists. More...
unsigned	llvm::getDebugMetadataVersionFromModule (const Module &M)
	Return Debug Info Metadata Version by checking module flags. More...
AssignmentInstRange	llvm::at::getAssignmentInsts (DIAssignID *ID)
	Return a range of instructions (typically just one) that have ID as an attachment. More...
AssignmentInstRange	llvm::at::getAssignmentInsts (const DbgAssignIntrinsic *DAI)
	Return a range of instructions (typically just one) that perform the assignment that DAI encodes. More...
AssignmentMarkerRange	llvm::at::getAssignmentMarkers (DIAssignID *ID)
	Return a range of dbg.assign intrinsics which use \ID as an operand. More...
AssignmentMarkerRange	llvm::at::getAssignmentMarkers (const Instruction *Inst)
	Return a range of dbg.assign intrinsics for which Inst performs the assignment they encode. More...
void	llvm::at::deleteAssignmentMarkers (const Instruction *Inst)
	Delete the llvm.dbg.assign intrinsics linked to Inst. More...
void	llvm::at::RAUW (DIAssignID *Old, DIAssignID *New)
	Replace all uses (and attachments) of Old with New. More...
void	llvm::at::deleteAll (Function *F)
	Remove all Assignment Tracking related intrinsics and metadata from F. More...
void	llvm::at::trackAssignments (Function::iterator Start, Function::iterator End, const StorageToVarsMap &Vars, const DataLayout &DL, bool DebugPrints=false)
	Track assignments to Vars between Start and End. More...
std::optional< AssignmentInfo >	llvm::at::getAssignmentInfo (const DataLayout &DL, const MemIntrinsic *I)
std::optional< AssignmentInfo >	llvm::at::getAssignmentInfo (const DataLayout &DL, const StoreInst *SI)
