This class implements an extremely fast bulk output stream that can only output to a stream.
Definition: raw_ostream.h:52
virtual bool is_displayed() const
This function determines if this stream is connected to a "tty" or "console" window.
Definition: raw_ostream.h:347
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
raw_fd_ostream & errs()
This returns a reference to a raw_ostream for standard error.
bool CheckBitcodeOutputToConsole(raw_ostream &stream_to_check)
