Public Member Functions
LexicalScopes ()=default
LLVM_ABI void initialize (const Module &)
Scan module to build subprogram-to-function map.
LLVM_ABI void scanFunction (const MachineFunction &)
Scan machine function and constuct lexical scope nest, resets the instance if necessary.
LLVM_ABI void resetModule ()
Reset the instance so that it's prepared for another module.
LLVM_ABI void resetFunction ()
Reset the instance so that it's prepared for another function.
bool empty ()
Return true if there is any lexical scope information available.
LexicalScope * getCurrentFunctionScope () const
Return lexical scope for the current function.
LLVM_ABI void getMachineBasicBlocks (const DILocation *DL, SmallPtrSetImpl< const MachineBasicBlock * > &MBBs)
Populate given set using machine basic blocks which have machine instructions that belong to lexical scope identified by DebugLoc.
LLVM_ABI bool dominates (const DILocation *DL, MachineBasicBlock *MBB)
Return true if DebugLoc's lexical scope dominates at least one machine instruction's lexical scope in a given machine basic block.
LLVM_ABI LexicalScope * findLexicalScope (const DILocation *DL)
Find lexical scope, either regular or inlined, for the given DebugLoc.
ArrayRef< LexicalScope * > getAbstractScopesList () const
Return a reference to list of abstract scopes.
LexicalScope * findAbstractScope (const DILocalScope *N)
Find an abstract scope or return null.
LexicalScope * findInlinedScope (const DILocalScope *N, const DILocation *IA)
Find an inlined scope for the given scope/inlined-at.
LexicalScope * findLexicalScope (const DILocalScope *N)
Find regular lexical scope or return null.
LLVM_ABI LexicalScope * getOrCreateAbstractScope (const DILocalScope *Scope)
Find or create an abstract lexical scope.
const Function * getFunction (const DISubprogram *SP) const
Get function to which the given subprogram is attached, if exists.
