Hello, It is likely that I missing something however I have to ask. We are working on Mull project https://github.com/mull-project which deals with LLVM IR in the first place so it is often that we encounter errors like the following one when we do things like parseAssemblyString(IR, Err, GlobalCtx);`: ``` test: <string>:7237:187: error: invalid field 'variable' !1526 = distinct

Hello Alex, This is an interesting approach! Thank you for that! I understand the basic idea but sadly... My skills in handling the IR are not very high, so I can't imagine where and when to replace the calls to b() with the trampoline. The only thing I can handle would be creating that trampoline variable. Also will this approach be a problem for really time critical tasks? Since I replace

Hello, everybody. We are working on a tool for mutation testing. The work is still in progress and far away from being done. However, we have got some results already. And we would like to share them with you. But, let me give you a brief introduction first. ### Mutation Testing In a nutshell, Mutation Testing is a way to evaluate a quality of a test suite. The approach suggests introducing a

Hi, thanks for your answer. I can reproduce your error in my HP-UX system and solved it ;-)). I built socalled software-depots for distributing the openssh-package and put the start command in the postinstall-script. The shell of this postinstall script has the bahavior that intr ^C won't work properly. So I did your trick with "/sbin/init.d/sshd stop/start" from a shell where ^C

Hi Stanislav, Sorry -- I am not much help here. I would like to get ObjC runtime support for the JIT, but have not had time to look in to it closely. When I last tested the idea (a couple of years ago now) we used selector registration and objc_readClassPair to get basic test cases working as you have, but ran into (possibly similar) failures on non-trivial test cases. I think the interpretation

Hi All, ORC's new concurrent compilation model generates some interesting lifetime and thread safety questions around LLVMContext: We need multiple LLVMContexts (one per module in the simplest case, but at least one per thread), and the lifetime of each context depends on the execution path of the JIT'd code. We would like to deallocate contexts once all modules associated with them have

Many thanks for the sample code, Alex. In the end I did it the same way OrcMCJITReplacement does it. Constructors and destructors are called and, thanks to LocalCXXRuntimeOverrides, the program does not crash on exit! But it does seem like there should be a simpler way; the learning curve is steep... Geoff On Thu, 21 Jun 2018 at 12:28, Alex Denisov <1101.debian at gmail.com> wrote: >

When OrcMCJITReplacement is given a new module, it asks for the module's constructors, gives them names like $static_ctor.0, $static_ctor.1, etc., and saves the mangled names in a map. Later, to execute them, it uses runViaLayer(), which looks for those symbol names in the given JIT layer. Could one not simply execute the constructors straight away, rather than naming them and looking them up

Hi all, Following the thread from http://lists.llvm.org/pipermail/llvm-dev/2017-January/109029.html, I am sending this email to give a status on GlobalISel progress and situation. We are pushing GlobalISel from the state of prototype to a production quality framework. We welcome help with patches, reviews, feedbacks and so on. As explained during the last developer meeting, we are aiming at

Hi David, Stanislav, Sorry for the delayed reply. Short version: There hasn't been any progress on this just yet, as I have been busy with an overhaul of the underlying ORC APIs. 1) Hack up something in RuntimeDyldMachO to handle the data structures > currently generated by clang. This is fragile, because the interface > between the compiler and the runtime is not documented, and is

Hi again, I had tried to follow David's suggestion to take a step back and look into codegen instead of hacking on RuntimeDyld but then I quickly realized that I don't understand what exactly needs to be done to fully register Objective-C runtime. I decided to iterate on JIT code again and somehow I found that I can hook into SectionMemory by subclassing it and working with its

I am currently trying to use LLVM (version 3.2) to generate code for a cluster where each node in the cluster will be running a 64-bit X86 chip, but *not* necessarily the same version of the X86 chip throughout the cluster. I am specifying that I want Position-Independent Code produced because the generated machine code may get moved (before it is executed) to a different logical address that

Hello, I was looking for Damien Miller, Markus Friedl or Theo de Raadt to possibly answer an SFTP question. I am having trouble locating an example and think the task can not be done. Do you have an example of an unix host machine initiating a file transfer to an ibm z/OS and create a mvs file? I have examples from appendix A of the IBM Ported Tools for z?OS Users Guide that shows how

Hi all, I'm having some trouble with inline asm expressions, more specifically how to create the right FunctionType for a given constraint set. So far it has worked well for inputs, but not for outputs. The inline asm support in this language (which is D, LLVMDC[1]) is through asm *statements*. I never have inline asm *expressions*, and outputs are always via memory. I D my test looks like

Hi all. I'm looking for an advice on how to deal with inefficient code generation for Intel Nehalem/Westmere architecture on 64-bit platform for the attached test.cpp (LLVM IR is in test.cpp.ll). The inner loop has 11 iterations and eventually unrolled. Test.lea.s is the assembly code of the outer loop. It simply has 11 loads, 11 FP add, 11 FP mull, 1 FP store and lea+mov for index
