Member Typedef Documentation

◆ InputList

typedef SmallVector<std::pair<types::ID, const llvm::opt::Arg *>, 16> clang::driver::Driver::InputList

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

Definition at line 169 of file Driver.h.

◆ prefix_list

Member Enumeration Documentation

◆ 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.

Returns: True if the entire string was parsed and there are no extra characters remaining at the end.
