TargetMachine::CGFT_AssemblyFile is exactly what I am trying to write out.

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,

...et access to the assembler of a jit-compiled function/module using llvm 3.8 and later. In 3.8 the interface to addPassesToEmitFile has changed and my old method doesn't work any more. In principle one gets the asm with targetMachine->addPassesToEmitFile( PM , *OS , llvm::TargetMachine::CGFT_AssemblyFile ) where *OS is a raw_pwrite_stream. The problem is that I only find use cases of raw_pwrite_stream where the derived class raw_svector_ostream is initialized on a SmallString, like SmallString<128> Str; raw_svector_ostream OS(Str); However, the assembler of the modules could be arbitrary...

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 thought of hacking the LTOCodeGenerator.cpp for the same . The bottom-line is that ,we need to u...

...ace. I mainly asked Yabin to provide a version that addresses concerns raised by Justin, to give further reviewers an up to date version to look at. With your comment, you actually pointed out a bug. Instead of: Target->addPassesToEmitFile(PM, FOS, TargetMachine::CGFT_AssemblyFile, CodeGenOpt::Default) We should use: bool UseVerifier = true; Target->addPassesToEmitFile(PM, FOS, TargetMachine::CGFT_AssemblyFile, UseVerifier) Though, I don't think that is the problem you where talki...

Hello! I'm using LLVM's JIT in my project. Is there any way to view assembly code of functions it generates without disassembling them from the memory?
