EntryIndex startClobber (InlinedEntity Var, const MachineInstr &MI)
Entry & getEntry (InlinedEntity Var, EntryIndex Index)
bool hasNonEmptyLocation (const Entries &Entries) const
Test whether a vector of entries features any non-empty locations.
void trimLocationRanges (const MachineFunction &MF, LexicalScopes &LScopes, const InstructionOrdering &Ordering)
Drop location ranges which exist entirely outside each variable's scope.
bool empty () const
void clear ()
EntriesMap::const_iterator begin () const
EntriesMap::const_iterator end () const
LLVM_DUMP_METHOD void dump (StringRef FuncName) const
Static Public Attributes
static const EntryIndex NoEntry = std::numeric_limits<EntryIndex>::max()
Special value to indicate that an entry is valid until the end of the function.

For each user variable, keep a list of instruction ranges where this variable is accessible.

The variables are listed in order of appearance.
