SourceLocation Loc
&#39;#&#39; location in the include directive
HeaderMappCollector collects all remapping header files.
std::string getIncludePath(const SourceManager &SM, SourceLocation Loc, const HeaderMapCollector *Collector)
This calculates the include path for Loc.
Definition: PathConfig.cpp:17
llvm::StringRef getMappedHeader(llvm::StringRef Header) const
Check if there is a mapping from Header or a regex pattern that matches it to another header name...
