Tagged union holding either a T or a Error.
void push_back(const T &Elt)
This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

LLVM_ABI void TokenizeWindowsCommandLineNoCopy(StringRef Source, StringSaver &Saver, SmallVectorImpl< StringRef > &NewArgv)
Tokenizes a Windows command line while attempting to avoid copies.
This is an optimization pass for GlobalISel generic memory operations.
LLVM_ABI raw_ostream & dbgs()
dbgs() - This returns a reference to a raw_ostream for debugging messages.
Error make_error(ArgTs &&... Args)
Make a Error instance representing failure using the given error info type.
Entry for a single option instance in the option data table.
