...time ago (llvm-svn june 2008) I asked here about a way to output the assembly code of my JIT generated code to a string, so I could use it to read it on the screen. I came up with this solution: std::string Err; const llvm::TargetMachineRegistry::entry* _arch = llvm::TargetMachineRegistry::getClosestTargetForJIT(Err); std::string FeaturesStr; llvm::TargetMachine* target(_arch->CtorFn(*_module, FeaturesStr)); assert(target && "Could not allocate target machine!"); std::ostringstream os; target->addPassesToEmitFile(*_passManager, os, llvm::TargetMachine::Assembl...

...ne once per LLVM module, which is still acceptable. I almost implemented this solution, but I have problems accessing the architecture dependent bits of the Module, i.e. TargetMachine objects specific for the current architecture, as selected by the --march option of the compiler. I tried using the getClosestTargetForJIT and getClosestStaticTargetForModule functions of the TargetMachineRegistry class. But all that was without success. I always get back only X86-based targets (which is the target architecture of my development machine) even though I explicitly select another target for cross-compilation by doing -...

Hello, I would like to know how to go about printing the x86 assembly output for a compiled function (I'm using the JIT). I saw there is a X86IntelAsmPrinter on doxygen. However, it takes several arguments I don't know how to fill in. Is there a helper function to create such a pass? Once I have the pass created, do I just add it to a FunctionPassManager? Thank you for your time, -

Hello, I'm trying to catch assembly output and do some formatting for its presentation while being executed. I face a problem, which is clear from the error, although I have no clue on how to do it otherwise. If generating the code for its asm output and then for jit execution I get: ********** static llvm::MachineFunction& llvm::MachineFunction::construct(const llvm::Function*, const
