Isn't there someone to help me with this issue? I'm very upset about this stupid problem which wasted the whole day. BTW, I can create JIT from main.cpp, but not in the required source file (runtime.cpp), so this is not about linking.

I see two problems in your code 1) you need to #include "llvm/ExecutionEngine/JIT.h" 2) you must pass an empty string to EngineBuilder::setErrorStr. See JIT::createJIT for the reason.

Hi, guys. Have a strange problem with LLVM in my project ( https://github.com/ababo/AntOS). Cannot instantiate JIT execution engine (NULL returns; message: Interpreter has not been linked in.). As you can see from the code I call InitializeNativeTarget. Also I tried to directly include the "llvm/ExecutionEngine/JIT.h" header, but with no success. I link with `llvm-config --ldflags

OK, that's my fault. I'm running jitted code on linux x86. 2011/11/9 Duncan Sands <baldrick at free.fr> > Hi Semion, > > > In my case the LLVM is built with assertions, but this doesn't help.

Which version of LLVM? At any rate I don't recall TLS working for the JIT. It may take some work. -eric On Nov 9, 2011, at 4:46 AM, Semion Prihodko wrote: > OK, that's my fault.

In my case the LLVM is built with assertions, but this doesn't help. From your answer I conclude that thread-local globals are fully implemented in x86 JIT. So this is strange... 2011/11/9 Duncan Sands <baldrick at free.fr> > Hi Semion, > > > Really strange situation: when I modify a thread-local GlobalVariable I > get a > > segfault.

...IT or I should use the old approach with llvm.eh instrinsics? Thanks. 2011/11/9 Eric Christopher <echristo at apple.com> > Which version of LLVM?

Hi! I have a little problem using LLVM and will be happy to get a solution. I need to handle in C++ code an uncaught unwind instruction while calling JIT (now I get segfault). I mean something like nonexistent ExecutionEngine::invokeFunction instead of callFunction. Setting llvm::JITExceptionHandling to true and enclosing the JIT-call within try/catch block does not help here, because there is no

Hi, guys. I have a beginner's question. The virtual machine I develop have instructions to dynamically allocate variable in stack and to free it (consistency of such instructions is checked before the actual jitting). To allocate memory in stack we have alloca IR instruction, but I didn't find any instruction to free it (such variables will be freed only when an enclosing function will

oops... so how can unwind stack up to invoke call? Is there an alternative to establish a custom exception handling? 2011/11/7 Duncan Sands <baldrick at free.fr> > >> Hi Semion, the unwind instruction has been removed from LLVM.

Hi, guys. Really strange situation: when I modify a thread-local GlobalVariable I get a segfault. It seems to be a bug, doesn't it? Can u suggest me some solution?

Hi Semion, > Really strange situation: when I modify a thread-local GlobalVariable I get a > segfault. It seems to be a bug, doesn't it? Can u suggest me some solution? build LLVM with assertions enabled. Then you may well get an assertion failure with a helpful error message rather than an obsc...

Hello, I'm french and I have some difficulties in carry out the semiones under R with an aim to carry out an interpolation by krigeage. My goal is to obtain a chart of the distribution of precipitations/temperatures in Europe starting from 73 different stations (and, of course, distributed irregularly on the chart, where use of the krigeage). Here, I carried out this...

Hi, guys! I write a virtual machine which uses LLVM as back-end code generator. The following function code causes strange "UNREACHABLE executed!" error: define void @p1(%1*) { %2 = call i8* @llvm.stacksave() %3 = alloca %0 %4 = getelementptr %0* %3, i64 1 %5 = ptrtoint %0* %3 to i64 %6 = ptrtoint %0* %4 to i64 %7 = sub i64 %6, %5 %8 = bitcast %0* %3 to i8* call void

Hi, guys. I'm a newbie to LLVM and have a very simple question. Which instructions should I use (in terms of IRBuilder calls) to allocate an array of bytes in stack (alloca?), then to work with it (from a given offset) as with integer (bitcast?). I mean something like that: unsigned char var[8]; unsigned int offset = 3; int val = *(int*)(&var+offset); /* read */ *(int*)(&var+offset)
