...mple, 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.

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? On Thu, 19 Sep 2019 at 00:47, David Blaikie via llvm-dev < llvm-dev at lists.llvm.org> wrote: > +Lang for JIT things > > On Tue, Sep 17, 2019 a...

Hi Yafei, As david told, you can make the symbols of your host process visible to the JIT'd code through DynamicLibrarySearchGenerator::getForCurrentProcess. On Thu, 19 Sep 2019 at 00:46, David Blaikie via llvm-dev < llvm-dev at lists.llvm.org> wrote: > +Lang Hames <lhames at gmail.com&gt...

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

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

In the Tutorial of the JIT https://llvm.org/docs/tutorial/BuildingAJIT1.html, illustrations and the full code listing are not the same, and the full code listing will not compile, this will make a lot of trouble to beginners since the JIT API is changing all the time. -------------- next part -------------- An HTML attachment was scrubbed...

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

I just copy the latest code in HowToUseJIT and run, but the EngineBuilder(std::move(Owner)).create() keeps return null, any idea why? Here's my CMakeList: cmake_minimum_required(VERSION 3.12) project(llvm_test) set(CMAKE_CXX_STANDARD 14) find_package(LLVM REQUIRED CONFIG) llvm_map_components_to_libnames(llvm_libs support core irreader orcjit native) add_executable(llvm_test main.cpp)

We know that in C++, the constructor of a static member will get called when the program starts up. I checked the generated IR code and found this is implemented by defining a __cxx_global_var_init() function and marked it as section ".text.startup" and assign it to @llvm.global_ctors. We also know that in C++, the constructor of a static thread_local member will *not* get called when

Hi, I want to create a double constant from a float constant, here's my code: auto* constFloat1 = static_cast<llvm::ConstantFP*>(llvm::ConstantFP::get(llvm::Type::getFloatTy(context), 3.1)); assert(constFloat1->getType() == llvm::Type::getFloatTy(context)); auto* constFloat2 = llvm::ConstantFP::get(llvm::Type::getDoubleTy(context), constFloat1->getValueAPF());

Hi all, I'm investigating on integrating a gc to my llvm project, and when I read this document <http://llvm.org/docs/Statepoints.html>, one sentence confused me: However, for a collector which wishes to relocate objects directly reachable from running code, a higher standard is required. I don't understand what the move "relocate objects directly reachable from running

Hi all, I wrote a compiler front end which generates IR codes, but due to the logic, the IR codes have a lot of instructions like unnecessary br jump, basic block creation, load instructions and expression which can be simplified. now I want to use built in passes to optimize the generated code, but after I read the tutorial: https://llvm.org/docs/tutorial/MyFirstLanguageFrontend, I found that I
