Rob, I can reproduce the behaviour you observe using llvm top-of-tree. I will try to look into it.

In the tutorial, it shows that multiple calls to pure functions (sin, cos) can be optimized. Without the

Cheers Lang! You were right, I was testing this on Linux. I was planning on committing these changes with the corresponding changes to the Kaleidoscope tutorial walk-through. Might be a bit of a surprise to have no explanation of what MCJITHelper and friends is doing. I'll try and make time to prepare some patches along these lines, as well as updating future chapters with the same fix.

Umm ok, but i've the strange feeling that i'm missing something.. First a simple question: getelementptr with

I'm using the gvn pass, not sure about basic-aa. I've copied the code as-is from http://llvm.org/docs/tutorial/LangImpl4.html#code and added "F->addFnAttr( Attribute::ReadOnly )" after "Function *F = Function::Create(FT, Function::ExternalLinkage, Name, TheModule)". The passes it sets up are: // Set up the optimizer pipeline. Start with registering info about

Hi all :) I'm new to llvm! I'm going through the kaleidoscope : compiling llvm IR to object code tutorial, code in the listings breaks and causes a segmentation fault. After some investigation through gdb, probably this constructor call, causing the segfault. |Program received signal SIGSEGV, Segmentation fault.|| ||0x00000000004afee0 in

I try to understand cmake build configuration. As an example, I copied Kaleidoscope from llvm examples to some other directory (e.g., /tmp/Kaleidoscope). What change(s) that I need to make to "CMakkeLists.txt" in order to build Kaleidoscope from /tmp/Kaleidoscope? Thank you. -------------- next part -------------- An HTML attachment was scrubbed...

(cc'ing llvm-dev) Hello Gregory, i just recompiled llvm from scratch, and was able to build the ocaml kaleidoscope bindings. Did you know the llvm's build system already can compile the kaleidoscope tutorials for you? You can run this to build them: make BUILD_EXAMPLES=1 Or just cd into the examples directory in your build directory, and run "make" there. Anyway, I think the

Hi David! Thanks for reaching out, the codegen part of the tutorial is fine, but when I try to generate the object code file, it throws segfault. Also please note that I'm using release build of llvm, actually I don't know whether that is the root cause or not. I also run through valgrind, it seems like a invalid read from stack. |||Error Summary: | |1 errors in context 1 of 1:

Can anyone point me in the right direction so i can have c like control flow in the Kaleidoscope example. for example in Kaleidoscope it's if a < 5 then //do something; to if (a < 5) { //do something } im trying to use LLVM to create an audio signal processing library/code for my music application to create music synths and audio effects. Thanks. -- View this message in

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
