llvm dev - May 2013 - [LLVMdev] How to write output of a backend to a memory buffer instead of a into a file?

Right now, I am using

TargetMachine::addPassesToEmitFile 
<http://llvm.org/docs/doxygen/html/classllvm_1_1LLVMTargetMachine.html#a356929c1f0d202e4a9d3202aff1dbb05>

to write the output of a backend to a file. How can I tell LLVM to write 
into a memory buffer instead?

Look at addPassesToEmitMC. One example would be its usage in MCJIT
(lib/ExecutionEngine/MCJIT/MCJIT.cpp), which indeed emits the binary into
memory and loads it from there.
