static COFFOptTable optTable

static constexpr opt::OptTable::Info infoTable[]

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.

StringRef - Represent a constant reference to a string, i.e.

constexpr const char * data() const

data - Get a pointer to the start of the string (which may not be null terminated).

StringRef save(const char *S)

Twine - A lightweight data structure for efficiently representing the concatenation of temporary valu...

Expected< opt::InputArgList > parse(StringRef Str)

InputArgList ParseArgs(ArrayRef< const char * > Args, unsigned &MissingArgIndex, unsigned &MissingArgCount, Visibility VisibilityMask=Visibility()) const

Parse an list of arguments into an InputArgList.

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.

raw_ostream & dbgs()

dbgs() - This returns a reference to a raw_ostream for debugging messages.

Entry for a single option instance in the option data table.
