llvm::StringMap<llvm::AssertingVH<llvm::Constant>, llvm::BumpPtrAllocator> clang::CodeGen::InternalVars

An ordered map of auto-generated variables to their unique names. It stores variables with the following names: 1) ".gomp_critical_user_" + <critical_section_name> + ".var" for "omp critical" directives; 2) <mangled_name_for_global_var> + ".cache." for cache for threadprivate variables.
