| std::function<std::optional<ArrayRef<dependency_directives_scan::Directive> >( FileEntryRef)> clang::PreprocessorOptions::DependencyDirectivesForFile |
Function for getting the dependency preprocessor directives of a file.
These are directives derived from a special form of lexing where the source input is scanned for the preprocessor directives that might have an effect on the dependencies for a compilation unit.
Enables a client to cache the directives for a file and provide them across multiple compiler invocations. FIXME: Allow returning an error.

True indicates that a preamble is being generated.
When the lexer is done, one of the things that need to be preserved is the conditional if stack, so the ASTWriter/ASTReader can save/restore it when processing the rest of the file. Similarly, we track an unterminated #pragma assume_nonnull.

| std::string clang::PreprocessorOptions::PCHThroughHeader |
If non-empty, the filename used in an #include directive in the primary source file (or command-line preinclude) that is used to implement MSVC-style precompiled headers.
When creating a PCH, after the #include of this header, the PCH generation stops. When using a PCH, tokens are skipped until after an #include of this header is seen.

When true, we are creating a PCH or creating the PCH object while expecting a #pragma hdrstop to separate the two.
Allow for a missing #pragma hdrstop, which generates a PCH for the whole file, and creates an empty PCH object.

Whether the compiler instance should retain (i.e., not free) the buffers associated with remapped files.
This flag defaults to false; it can be set true only through direct manipulation of the compiler invocation object, in cases where the compiler invocation and its buffers will be reused.

Referenced by InitializePredefinedMacros().
When enabled, preprocessor is in a mode for parsing a single file only.
Disables #includes of other files and if there are unresolved identifiers in preprocessor directive conditions it causes all blocks to be parsed so that the client can get the maximum amount of information from the parser.
