Member Variables

public IntrusiveRefCntPtr<clang::DiagnosticsEngine> Diags = nullptr

Receives diagnostics encountered while parsing command-line flags. If not provided, these are printed to stderr.

public IntrusiveRefCntPtr<llvm::vfs::FileSystem> VFS = nullptr

Used e.g. to probe for system headers locations. If not provided, the real filesystem is used. FIXME: the driver does perform some non-virtualized IO.

public bool RecoverOnError = false

Whether to attempt to produce a non-null (possibly incorrect) invocation if any errors were encountered. By default, always return null on errors.

public bool ProbePrecompiled = false

Allow the driver to probe the filesystem for PCH files. This is used to replace -include with -include-pch in the cc1 args. FIXME: ProbePrecompiled=true is a poor, historical default. It misbehaves if the PCH file is from GCC, has the wrong version, etc.

public std::vector<std::string>* CC1Args = nullptr

If set, the target is populated with the cc1 args produced by the driver. This may be populated even if createInvocation returns nullptr.
