Member Typedef Documentation

CC1ToolFunc

using clang::driver::Driver::CC1ToolFunc = llvm::function_ref<int(SmallVectorImpl<const char *> &ArgV)>

Pointer to the ExecuteCC1Tool function, if available.

When the clangDriver lib is used through clang.exe, this provides a shortcut for executing the -cc1 command-line directly, in the same process.

Definition at line 305 of file Driver.h.

InputList

using clang::driver::Driver::InputList = SmallVector<InputTy, 16>

A list of inputs and their types for the given arguments.

Definition at line 235 of file Driver.h.

InputTy

using clang::driver::Driver::InputTy = std::pair<types::ID, const llvm::opt::Arg *>

An input type and its arguments.

Definition at line 232 of file Driver.h.

prefix_list

typedef SmallVector<std::string, 4> clang::driver::Driver::prefix_list

A prefix directory used to emulate a limited subset of GCC's '-Bprefix' functionality.

FIXME: This type of customization should be removed in favor of the universal driver when it is ready.

OpenMPRuntimeKind

enum clang::driver::Driver::OpenMPRuntimeKind

Enumerator
OMPRT_Unknown	An unknown OpenMP runtime. We can't generate effective OpenMP code without knowing what runtime to target.
OMPRT_OMP	The LLVM OpenMP runtime. When completed and integrated, this will become the default for Clang.
OMPRT_GOMP	The GNU OpenMP runtime. Clang doesn't support generating OpenMP code for this runtime but can swallow the pragmas, and find and link against the runtime library itself.
OMPRT_IOMP5	The legacy name for the LLVM OpenMP runtime from when it was the Intel OpenMP runtime. We support this mode for users with existing dependencies on this runtime library name.
