...th no modules: jitstate will be 0 and therefore we have a null-pointer exception. The function returns a boolean for success/failure, however, so you would expect to be able to call it and get false back. Should we be checking for jitstate != 0 before accessing the variable? - if (jitstate->getModule() == M) { + if (jitstate && jitstate->getModule() == M) { Verena

Hello, I want to add a global variable of arrayType in my MachineFunctionPass. However, I only get const Module from MachineFunction.getMMI().getModule(). I can't add any global variable to a const Module. Another way is to add a global variable in doInitialization in my MachineFunctionPass, but I can't determine the size of my arrayType for global variable in doInitialization. Is there any suggestion that can help me achieve this? Tha...

Hi, I am using LLVM 3.1, and wants to print the machine code of JIT IR I try the following method EngineBuilder builder(&ctx.getModule()); builder.setEngineKind(EngineKind::JIT); * TargetMachine * tm = builder.selectTarget(); tm->Options.PrintMachineCode = true;* engine = builder.create(); and somewhere in my code, I use runJITonFunction(); Another question is that I am not sure when JIT would dump machine code...

...ion. Can anyone tell me if I am wrong: ExecutionEngine: Module &CurMod; const TargetData *TD; JIT: TargetMachine &TM; TargetJITInfo &TJI; MachineCodeEmitter *MCE; I specifically did not protect the ExecutionEngine::CurMod member because a reference is returned via ExecutionEngine::getModule(). If access to it must be serialized, it must be done very carefully. I tried to make getModule return a constant reference, but that quickly led me into deep trouble in the world of const correctness. I've attached my patch against the latest CVS. There is one "trivial" fix wh...

Gordon, I think I can make it work if we have the following additional function in LLVM-C: LLVMModuleRef LLVMGetModule(LLVMModuleProviderRef MP) { return wrap(unwrap(MP)->getModule()); } Do you think you could add that? Can I send you a patch? Thanks & Regards, -Mahadevan.
