raw_pwrite_stream to string or stdout?
TargetMachine::addPassesToEmitFile(..)
requires as its 2nd argument an raw_pwrite_stream.
Is it possible to create such a thing which either writes into a
standard string or streams to outs() ?
Thanks,

raw_pwrite_stream to string or stdout?
Note that raw_fd_ostream is not seekable, and hence will not be suitable as
addPassesToEmitFile output stream.

Using an MCStreamer Directly to produce an object file?
...buffer:
std::string ofile("/home/users/avose/hpcgp/hpcgp_rundir/tmp.o");
std::unique_ptr<tool_output_file> Out = GetOutputStream(ofile);
if (!Out) {
return 1;
}
std::unique_ptr<buffer_ostream> BOS;
raw_pwrite_stream *OS = &Out->os();
if (!Out->os().supportsSeeking()) {
BOS = make_unique<buffer_ostream>(Out->os());
OS = BOS.get();
}
This also seems to do OK. Now I would think I can finally get around to
making the code emitter and the MCStreamer:
MCCodeEmitter *CE = TheTarget->createMCCodeEmitter(*MCII, *MRI, Ctx);
MCAsmBackend *...
