Detailed Description

The options of a library that declares them in TableGen rather than as cl::opt (see llvm/Option/LibraryOptions.h).

ParseCommandLineOptions hands every argument naming one of them to parse(). This lets libraries move off cl::opt while tools still parse argv with cl::, and goes away once tools parse argv without cl::.

Member Function Documentation

forEachOption()

virtual void llvm::cl::LibraryOptions::forEachOption ( function_ref< void(StringRef Spelling, StringRef MetaVar, StringRef Help)> Fn ) const

pure virtual

Calls Fn with the spelling of each option without its prefix (e.g.

"x" or "x="), its metavariable, and its help text. Only -help-hidden lists the options.

References Help().

parse()

virtual Error llvm::cl::LibraryOptions::parse ( ArrayRef< const char * > Args, unsigned & Consumed )

pure virtual

Parses the option spelled by Args[0], which may take Args[1] as its value, and sets Consumed to the number of arguments it spans.

The strings in Args remain valid until reset().

Implemented in llvm::opt::LibraryOptionsParser.

reset()

virtual void llvm::cl::LibraryOptions::reset ( )

pure virtual

Restores the default values.

Implemented in llvm::opt::LibraryOptionsParser.
