Hi Dmitri, You're right. The lli code should be cleaned up. As David said, there was a time when the call to invalidate the instruction cache was necessary. It isn't necessary anymore. -Andy -----Original Message----- From: Dmitri Rubinstein [mailto:dmitri.rubinstein at googlemail.com] Sent: Tuesday, June 04, 2013 7:20 AM To: David Tweed Cc: Kaylor, Andrew; LLVM Dev Subject: Re:

Hello All I 'm studing LLVM/Clang and trying to follow the Kaleidoscope tutorial (Release 2.6 version). I found some minir docu-bugs and added them to Bugzilla. However, Now I found a show-stopper for me, the toy (v4) demo does build, but does crash, on any input. Even a simpe ';'! Looking into the (demo-code) found the that the JIT can't be build/ created,/loaded/... Which

Look at what is in <llvm source root>/examples/Kaleidoscope/toy.cpp. This is the final version of the tutorial and worked the last time I played with 2.6.

Hi all, I tried to modify Kaleidoscope Tutorial (toy.cpp from llvm/examples/Kaleidoscope/Chapter7, LLVM 3.3 release branch) in order to use MCJIT instead of JIT. I get segmentation fault when running toy.cpp with fibonacci example from the tutorial. My modified toy.cpp is in attachment and still works with JIT (when #define USE_MCJIT line is commented out). I read discussions regarding

Hi Dmitri, You might want to try replacing the call to JMM->invalidInstructionCache() with a call to TheExecutionEngine->finalizeObject(). If you are getting a non-NULL pointer from getPointerToFunction but it crashes when you try to call it, that is most likely because the memory for the generated code has not been marked as executable. That happens inside finalizeObject, which also

Hi all, I am new to LLVM and have been working through the Kaleidoscope tutorial. Everything is working fine so far except for local externs (as opposed to things like the math functions, which are working). Note that I have seen this bug with the reference code listing, as well as my own code. link to code: https://llvm.org/docs/tutorial/LangImpl05.html#full-code-listing [c34n10 kaleidoscope]

Hi, I'm learning the tutorial. http://llvm.org/docs/tutorial/ I'm wondering if there is already a git repository of the examples in the tutorial so that I don't have to copy the code from the webpage. Thanks! -- Regards, Peng

Hi all, I'm a new user to LLVM. Not really sure if this is the correct place to post, since there isn't really any other forums around. Anyway, the issue I'm encountering is that, I was trying out the first tutorial (http://llvm.org/docs/tutorial/JITTutorial1.html). I attempted to do this in another folder that was copied from llvm/projects/sample. I created a new folder called

I'm going through the Kaleidoscope tutorial, adding the codegen() functions: https://llvm.org/docs/tutorial/LangImpl03.html. I cannot find any discussion of header files to include, (other than the include of llvm/ADT/STLExtras.h in the lexer/parser code), and the compilation is failing due to several undefined symbols: LogErrorV, Value, LLVMContext, APFloat, and others. I've been hunting

Hi Everyone, If you're JITing with LLVM and haven't made the switch to MCJIT already, now is the time. As per discussions on the mailing list and at the last dev meeting, LLVM 3.5 will be the last release to support the old JIT infrastructure. Now that LLVM 3.5 has branched, we plan to start removing the old JIT from the mainline. If you're looking for help in making the switch, Andy

Good morning everyone, It seems the LLVM tutorial is not up to date anymore and doesn't compile as is... The function makeLLVMModule() function doesn't compile at all. Here is a fix: Module *makeLLVMModule() { // Caches the global context to share it with new Module() and IntegerType::get() calls LLVMContext &context = getGlobalContext(); // Module Construction

Hi folks, I'm working on migrating a JIT compiler from the old ORCv1 JIT APIs to the newer ORCv2 ones and am having some trouble getting the code from chapter 1 of the "Building a JIT" [1] tutorial working properly. I have previously walked through the "My First Langauge" [2] tutorial and that went smoothly using the provided JIT class, but using the one from the JIT

Hi, I’d like to propose adding a new example directory (llvm/examples/IRTransforms) as a new home for example code used by various tutorials. After talking to a few people at the Developers meeting, it became clear to me that it would be valuable to have the code examples for various tutorials in-tree to keep them from bit-rotting and make it very easy to build them. I’d suggest adding new IR

Hello, i mainly code in c/c++ on linux. I would like to know if I can generate code at runtime using llvm, like libgccjit -> https://gcc.gnu.org/onlinedocs/jit/ My needs are : create functions, conditions, loops at runtime. libgccjit does the job pretty well but I would like to test llvm too (licence issue). Is it possible ? Is there a resource that helps in that regard ? Kaleidoscope
