This file defines DenseMapInfo traits for DenseMap.
This file defines the DenseMap class.
This file defines the DenseSet and SmallDenseSet classes.
Allocate memory in an ever growing pool, as if by bump-pointer.
A structured debug information entry.
Utility class that carries the DWARF compile/type unit and the debug info entry in an object.
A string table that doesn't need relocations.
PointerIntPair - This class implements a pair of a pointer and small integer.
SmallString - A SmallString is just a SmallVector with methods and accessors that make it work better...
StringMap - This is an unconventional map that is specialized for handling keys that are "strings",...
size_type count(StringRef Key) const
count - Return 1 if the element is in the map, 0 otherwise.
bool insert(MapEntryTy *KeyValue)
insert - Insert the specified key/value pair into the map.
StringRef - Represent a constant reference to a string, i.e.
Small helper that resolves and caches file paths.
StringRef resolve(const std::string &Path, NonRelocatableStringpool &StringPool)
Resolve a path by calling realpath and cache its result.
Stores all information relating to a compile unit, be it in its original instance in the object file ...
This class gives a tree-like API to the DenseMap that stores the DeclContext objects.
PointerIntPair< DeclContext *, 1 > getChildDeclContext(DeclContext &Context, const DWARFDie &DIE, CompileUnit &Unit, bool InClangModule)
Get the child of Context described by DIE in Unit.
A DeclContext is a named program scope that is used for ODR uniquing of types.

bool setLastSeenDIE(CompileUnit &U, const DWARFDie &Die)
Set the last DIE/CU a context was seen in and, possibly invalidate the context if it is ambiguous.
std::error_code real_path(const Twine &path, SmallVectorImpl< char > &output, bool expand_tilde=false)
Collapse all .
StringRef filename(StringRef path, Style style=Style::native)
Get filename.
StringRef parent_path(StringRef path, Style style=Style::native)
Get parent path.
void append(SmallVectorImpl< char > &path, const Twine &a, const Twine &b="", const Twine &c="", const Twine &d="")
Append to path.
