similar to: Nice way to add load shared library for use in JIT

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:

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

You can add symbols from Archieve via StaticLibrarySearchGenerator.

>> 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

Hi all, I'm struggling to get lli work on qemu-system-arm. I already boot the system with a debian squeeze rootfs which contains a statically cross-compiled lli for armel. When I run ./lli hello.bc, I got the following error msg: ./lli: error creating EE: /lib/: cannot read file data: Is a directory afaik, this error is related to lli using dlopen() with a NULL path to resolve symbols for

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>

This message didn't seem to have been somewhat forgotten. Here is a reply. When you constructed the data.frame, all strings were converted to factors. If you didn't want that, it would have been possible to specify it: df<-data.frame(a=a,b=b,c=c,stringsAsFactors=F) Then everything would work as intended: one.line<-as.character(df[df$a=="Abraham",]) Actually, the real

Hi, Probably some of the leaks Valgrind reports are spurious, but the numbers seem to be significant enough to demand some attention: ==10132== LEAK SUMMARY: ==10132== definitely lost: 15,624 bytes in 558 blocks. ==10132== indirectly lost: 44,548 bytes in 1,591 blocks. ==10132== possibly lost: 37,576 bytes in 98 blocks. ==10132== still reachable: 1,336,876 bytes in 1,364 blocks.

Hi Larry, Thanks so much! This seems to do the trick. I would have spun my wheels for > a long time before discovering all of this, wow. 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. Do I even want to know what additional chickens need to be sacrificed

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,

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.

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

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,

Hi all, Is there a function attribute or otherwise way to query whether a function could write to memory that outlives itself? For example writing to a global or memory passed in via a function argument would be writing to memory that outlives the function, but writing to a stack variable or allocation that isn't returned would not.
