Hi Yafei, First 2 chapters of the tutorial is up-to-date with ORC v2 APIs. I hope nothing changed in docs and code. Did you got compilation errors?

For example, the illustrate part says "ES.getMainJITDylib().setGenerator" while the full code list says "ES.getMainJITDylib().addGenerator", I guess the API is changed, the tutorial part is up to date while the full code list leaves to the old version.

When I declare some functions in my IR code which belongs to the C standard library(printf for example), the JIT will report that symbol cannot found. So is there any way I can add these libraries to my JIT? P.S. When I using lli, the printf will work, I guess lli is a JIT(right?) and it somehow knows where to find the symbol printf -------------- next part -------------- An HTML attachment was

Hi Yafei, As david told, you can make the symbols of your host process visible to the JIT'd code through DynamicLibrarySearchGenerator::getForCurrentProcess.

I found a private ErrorStr member, but didn't find the get function of this member, could you tell me how I can get the error message?

Hi all, I am using LLVM for JIT use-case and compile functions on the fly. I want to "free" the modules after some time and reclaim any memory associated with it. I am using the SimpleORC API <https://llvm.org/docs/tutorial/BuildingAJIT1.html> now. Is there an API to "free" all the memory associated with the module? I use one "compiler" instance (think similar

Hi, I wrote a compiler that generate IR code and run it on the JIT, and there randomly crashed due to "corrupted size vs. prev_size" depends on the IR code generated from the source code. Here's how I created the JIT: llvm::InitializeNativeTarget(); llvm::InitializeNativeTargetAsmPrinter(); llvm::InitializeNativeTargetAsmParser(); // create jit llvm::orc::ExecutionSession

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 am trying to run the toy example provided on http://llvm.org/docs/tutorial/BuildingAJIT1.html. However, I am running into a file not found error for llvm/ExecutionEngine/Orc/Core.h. Meanwhile other llvm headers seem to link properly. Can someone help me out, please? Thanks in advance.

I just copy the latest code in HowToUseJIT and run, but the EngineBuilder(std::move(Owner)).create() keeps return null, any idea why?

Hi Praveen, Thanks for pointing that out :) That's my mistake. I might have been misidentifying the issue with the assert statement. With those fixes made function calls seem to all call the first function called in the REPL. For example: ready> def fib(n) if (n < 2) then n else fib(n - 1) + fib(n - 2); ... ready> fib(40); Evaluated to 102334155.000000 ready> fib(10); # This

Sir, I am working on a project to provide LLVM JIT support for a specific processor architecture. I have an overall idea about llvm. Please guide where to start from a practical or implementation view point. Regards, Siddharth -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi David, Thanks for your answer. Just to clarify, I would like to create 2 3 instructions put them in a function and execute them. Do you still think the JIT would be the best option?

HI Lang, Thanks a bunch for the reply. That worked great for on my end and is a pretty tiny change. Really appreciate all the work you've done on this new JIT stuff and putting together those great tutorials.

Is the ORC API currently stable enough to be recommended for use? If so, what documentation and example code represents the current recommended way of doing things with it? https://llvm.org/docs/tutorial/BuildingAJIT1.html says: "Warning: This text is currently out of date due to ORC API updates. The example code has been updated and can be used. The text will be updated once the API churn

Hello LLVM developers, I am developing a small project using LLVM. The objective is to provide dynamic loading via JIT compilation of C++ code contained in a (TS) module. For this reason, I would like to return an explicitly raw void pointer (resembling libdl's `void *dlsym(void *, char const *);` as closely as possible) to the compiled result. The MCJIT class offers the most convenient API

Hi all, I am following the LLVM JIT tutorial API based on: https://llvm.org/docs/tutorial/BuildingAJIT1.html I have 2 independent questions: 1. The tutorial mentions that "*will defer compilation of the module until any of its definitions is looked up*". Does that mean to force eager compilation, i have to keep track of all functions added to the Module and do a lookup? I want the

Hi, I'm learning to use llvm api to generate IR code, I got two good tutorials, https://llvm.org/docs/tutorial/ and https://www.ibm.com/developerworks/library/os-createcompilerllvm1/index.html, but non of those showed how to implement a function pointer(or at least there is but I didn't find out). For example I got a c style code like this: int foo(int i) { return ++i; } int

Correct, with a couple of nit picks. Relocation isn't an optimization the collector performs.  It's a key primitive the collector is built upon.  Being unable to relocate is not an allowed state.  (i.e. pinning can't be required by the compiler) When you talk about variables, that's true for the *source* language and for the *abstract* machine before lowering.  After lowering
