Hi Guys , We enabled the LTO on our code base and found that LTO uses the integrated/builtin assembler to emit the final optimized code .O (FileType= CGFT_ObjectFile) . Can we bypass this semantic ,for something like you emit .S file (FileType=CGFT_AssemblyFile), Then we pass this .S file to our native assembler and the linker .....any switch/ options do so ? i.e something like as we have "-no-integrated-as" for clang driver . Currently ,we...

...ronment part of the triple. (i686-pc-linux-gnu becomes i686-pc-linux-JIT). As the target triple is easy to change, this is currently the solution I use. What do you think ? Do you see another possibilities ? - Currently I'm using the LLVMTargetMachine::addPassesToEmitFile with FileType set to CGFT_ObjectFile, and with the triple environment name hack, I am able to create the correct streamer : if (Triple(TargetTriple).getEnvironmentName().equals("JIT")) { AsmStreamer.reset(createJITStreamer(*Context, *TAB, Out, MCE)); } else { AsmStreamer.reset(createMachOStreamer(*Context,...

I do have an opinion, but don't have enough time to comment in much depth. The approximate approach I had in mind sounds like what you describe, though, the JITObjectWriter is the core piece, the other pieces probably fall into place as it becomes obvious if they are needed. It should be pretty straightforward to bring up something which works for running code with no external symbols, if you

This sounds possibly problematic to me. The IR should be created with the correct address space to begin with. Changing this in the middle sounds suspect. > After this

Hi! Is it possible that you add an example how to write a .o with llvm? Just like examples/ModuleMaker but instead of printing to stdout writing a .o file as starting point for the new MC functionality. -Jochen
