static bool isStdout(StringRef Filename)
CleanupInstaller(StringRef Filename)
std::string Filename
The name of the file.
bool Keep
The flag which indicates whether we should not delete the file.
StringRef - Represent a constant reference to a string, i.e.
ToolOutputFile(StringRef Filename, std::error_code &EC, sys::fs::OpenFlags Flags)
This constructor's arguments are passed to raw_fd_ostream's constructor.
std::error_code remove(const Twine &path, bool IgnoreNonExisting=true)
Remove path.
void DontRemoveFileOnSignal(StringRef Filename)
This function removes a file from the list of files to be removed on signal delivery.
bool RemoveFileOnSignal(StringRef Filename, std::string *ErrMsg=nullptr)
This function registers signal handlers to ensure that if a signal gets delivered that the named file...
This is an optimization pass for GlobalISel generic memory operations.
raw_fd_ostream & outs()
This returns a reference to a raw_fd_ostream for standard output.
@ Keep
No function return thunk.
Implement std::hash so that hash_code can be used in STL containers.
