Utility function to add a system include directory with extern "C" semantics to CC1 arguments.

## ◆ getTargetAndModeFromProgramName()

ParsedClangName ToolChain::getTargetAndModeFromProgramName | ( | StringRef | ProgName | ) |
| static

Return any implicit target and/or mode flag for an invocation of the compiler driver as `ProgName`.

For example, when called with i686-linux-android-g++, the first element of the return value will be set to `"i686-linux-android"` and the second will be set to "--driver-mode=g++"`. It is OK if the target name is not registered. In this case the return value contains false in the field TargetIsValid.

Precondition
  `llvm::InitializeAllTargets()` has been called.

Parameters

  ProgName | The name the Clang driver was invoked with (from, e.g., argv[0]).

Returns
  A structure of type ParsedClangName that contains the executable name parts.

## ◆ printVerboseInfo()

virtual void clang::driver::ToolChain::printVerboseInfo | ( | raw_ostream & | OS | ) | const

Dispatch to the specific toolchain for verbose printing.

This is used when handling the verbose option to print detailed, toolchain-specific information useful for understanding the behavior of the driver on a specific platform.
