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 to KaleidoscopeJIT class with its ExecutionSession, CompileLayer etc.) in my process. Is there an API to reset all memory used? Does deleting the &quo...

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...

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.

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:

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 https://llvm.org/docs/tutorial/BuildingAJIT1.html says: "Warning: This text is currently out of date due to ORC API updates.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 dies down." Does that mean the example code presented on the page, or some of the files under llvm/examples? If...

Hi all, I'm trying to understand how the Module object works more in details, so suppose I've an empty module and I'd like to know if it is possible to add instructions at runtime and execute it.

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 module...

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

Hello, I am a bit curious about the rationale for the current callback-based object cache API. For Numba, it would be easier if there would be a simple procedural API: - one method to get a module's compiled object code - one method to load/instantiate a module from a given piece of object code I manage to get around the callback-based API to do what I want, but it's a bit weird to work

Hi Kevin, Koffie, We will start migrating to ORC for next release, but for now, this release > invoke delete after remove right? MCJIT's removeModule method does not delete the module. You'll need to do that manually. OrcMCJITReplacement is a bug-for-bug compatible implementation of MCJIT using ORC components, so it does not free the memory either. Does this mean MCJIT is

Hi, I want to use a function defined in c(++)-code from code generated by llvm. For this I use ExecutionEngine.addGlobalMapping(). I started with the JIT execution engine and everything worked, then I switched to the interpreter engine and it stopped working, but only if compiled on a Linux system. More precisely it works if I use llvm 3.8.1 + gcc (Linux) + JIT llvm 3.8.0 + mingw-gcc

Hi Koffie, I'd highly recommend switching to ORC from MCJIT. It is much more flexible when it comes to memory-management. 1. I took the approach of 1 execution engine with multiple modules (I'm not > removing modules once they have been added). During profiling, I noticed > that the memory usage is high with a lot of code.
