similar to: [LLVMdev] Running LLVM JIT on qemu-system-arm

Hi James, Thanks for your information. Could you suggest any other framework that I could use for making a custom JIT for ARM? I am doing research on JIT compilation for a heterogeneous processor system.

Hi, Would it be possible to make the following slight change to ExecutionEngine::create()? I would like to be able to disable the automatic enumeration of loaded modules, and the subsequent searching for undefined symbols (using SearchForAddressOfSymbol). I propose adding an extra parameter to the function definition, defaulting to true. static ExecutionEngine *create(ModuleProvider *MP,

Hi Rob, Can you comment on exactly what the problem is you want to solve? Is it a performance issue with LoadLibraryPermanently, or do you simply not want the external symbols to be resolved from within the JIT? - Daniel On Wed, Jul 22, 2009 at 11:22 PM, Evan Cheng<evan.cheng at apple.com> wrote: > > On Jul 22, 2009, at 9:43 PM, Rob Grapes wrote: > >> Hi, >> >>

Hi Daniel, In my case ExecutionEngine::create() loads 40 modules, then each time I try to resolve a symbol that I know is in a DLL that I supply, it looks through all 40 modules first. This is on Windows, so I get the following modules loaded: ntdll.dll, kernel32.dll, USER32.dll, GDI32.dll, SHELL32.dll, ADVAPI32.dll, RPCRT4.dll, Secur32.dll, msvcrt.dll, SHLWAPI.dll, ole32.dll, OLEAUT32.dll,

You can add symbols from Archieve via StaticLibrarySearchGenerator.

How did you make your process symbols visible to ORC jit? Yes. It's the constructor that generates the undefined symbol error.

Winbind appears to lose connections every once in a while. Is there a way to tell which Domain Controller winbind is making connections to? I have 3 DCs currently and trying to track down the problem. Thanks, Toan

Greetings, LLVM wizards. We are using Clang and Orc JIT (v1) to compile and execute C++ code on the fly. If a C++ module calls functions from external libraries, we add them via DynamicLibrary::LoadLibraryPermanently(). The problem we have run into recently is when a module calls a function from the STL -- in particular this swap() function for input streams: #include <fstream>

>> llvm::sys::DynamicLibrary::LoadLibraryPermanently(nullptr) This is one is a bit tricky and hard to find. I spent quiet some time digging into MC and ORC JIT execution engines trying to find what makes them work. The problem is that this trick (LoadLibraryPermanently) happens inside of EngineBuilder, despite that the functionality belongs to a JIT engine itself, not to the builder. I

I found the following problem when I try to debug "target does not support mc emission" in linux (the same code executes OK in windows): Below is a snippet extracted from this method, if (UseMCJIT && ExecutionEngine::MCJITCtor) { ExecutionEngine *EE = ExecutionEngine::MCJITCtor(M, ErrorStr, JMM, OptLevel,

Hi, Today, I've made the transition from LLVM 2.1 to 2.3. I invoke opt with two dynamic libraries to "-load", the first of which contains transformation passes and support code whereas the second one provides extra passes which make use of the first library's support code. In other words, the symbols loaded in for the first library should be available when the second

Hello, Attached is a simple fix for getting error messages from dlerror in LoadLibraryPermanently. The current code modifies the value of a pointer that is passed by value, so the caller never gets the message.

Albert and Anton, thanks for all the answers. I tried to load a DLL with DynamicLibrary::LoadLibraryPermanently and it works perfectly, so there is no need to use ExecutionEngine::addGlobalMapping. However Function objects still need to be constructed since they are required when creating a call, right? Victor 2009/6/15 Albert Graef <Dr.Graef at t-online.de> > Victor Zverovich wrote:

Hi, In ExecutionEngine.cpp, when the JIT or the Interpreter have not been linked in then EngineBuilder::create fails without setting ErrorStr. I've attached a patch to fix this.

No worries. :) I'll try to keep this in mind and make sure I address it in future Kaleidoscope tutorial chapters - these issues tripped me up the first time I encountered them too.
