similar to: Berlin: LLVM Hackday #1, Betahaus, Oct. 22nd

I have a similar build tree to what you describe on Windows, but I get this: $ clang -c -emit-llvm repro_input.cpp -std=c++11 -o t.bc $ lli t.bc LLVM ERROR: Program used external function '??_7type_info@@6B@' which could not be resolved! It looks like people have already reported similar issues. Have you done anything to get past this kind of problem? On Sat, Oct 22, 2016 at 7:18 AM,

HI Stefan, CC'ing Reid Kleckner, who might have some insight here, and llvm-dev as this may be of interest to other windows JIT users. I am facing the issue that C++ dynamic_cast doesn't work for types > loaded from object files with RuntimeDyLd. <snip> Do you think it is possible that RuntimeDyLd misses type info data in > the COFF file or doesn't wire it up

Appreciations for the initiative! There are some people in the Berlin C++ user group [1] who may be interested. Also there was an active compiler meetup group [3] a few years ago. As far as I know these guys mostly joined the Strange Group Berlin [2], but may still be interested in a more compiler-focused meetup. For the people cc'd: please let us know who'd like to participate in a LLVM

"git remote get-url" is apparently fairly new, the old version is "git config remote.origin.url". Might be worth using that for compatibility.

Hi Stefan Thank you! In case, you missed in llvm-dev listing: you can find the proposal here : link. <https://docs.google.com/document/d/1202EcXlWMQ8yxu5qD0b5fE0a_kihlcaPNpZo_Jk0YeQ/edit?usp=sharing> Thanks for working on summarising the Bugzilla tickets to track the recent changes in ORC this is really helpful.

Hello everyone A previous thread about OrcJIT brought up bug reports on Bugzilla. A quick search gives 20+ results: https://bugs.llvm.org/buglist.cgi?component=OrcJIT&list_id=162232&query_format=advanced&resolution=--- While some of them are obviously outdated (addModuleSet API cleanup [1]), others may actually be relevant again (Small code model? [2]). If you reported one of them,

Hi Stefan, David, This is very interesting stuff - it adds a dimension of error security that Error/Expected can't provide on their own. I think it would be interesting to try to build a tool around this. Did you identify many cases where "real work" (in your example, the nullptr dereference" was being done in an error branch? My suspicion is that that should be rare, but that

Hey Lang, That is really cool :D Is the creation of that table a Windows thingy or is this the way the LLVM handles it? Also… since it is COFF related – the never ending story of “finding my global constructors” first of all: Yes! I tried using the “initialize” function of LLVMJIT – however this only worked when I was loading a Module. When I added the object file (from the same source) the

Hey Lang and Stefan, Using dllimport on my “planschiValue” actually worked! But I have no idea why, because the relocation is still a REL32 if I use dumpbin… So how is it possible for that to work? However… when I load an COFF object file, am I able to change the relocations to dllimport somehow? I honestly can’t imagine how this would work since the machine code is probably already adjusted to

Hi all In case anyone has a remote to the (unofficial) https://github.com/llvm-mirror, please note that all the repos are at least 8 days behind. There's no warning about it. The page still says it's "Updated every five minutes". Best Stefan -- https://flowcrypt.com/pub/stefan.graenitz at gmail.com

No issues pushing commits here, (despite it being my first commit via git!).

Yes definitely, testing a small piece of code like the GlobPattern::create() example, it would mostly indicate missing unit tests or insufficient test data. In contrast to unit tests, however, it can also verify correct handling of errors passed between function call hierarchies in more complex scenarios. For this I should point to the other example in the code, where it's applied to

Hello everyone, My name is Alex, I'm hobbyist compiler hacker who lives in Berlin, Germany now. I'm thinking about organising "LLVM Social" meetups in Berlin, however I don't really know how many people are here, and how many of them are interested in getting in touch. If you want to participate or have any questions - feel free to answer to this thread, or to send me a

Hi Björn I made a workaround for this specific issue a long time ago for the Projucer C++ JIT Engine. It basically forwards the call to another stub that provides enough space to encode a full 64-bit address. The patch is based on LLVM 3.9, so I guess it won't work out-of-the-box on a recent release, but it may give you enough hints to figure it out on your own:

Hi Stefan, I just tried the -jit-kind=orc-lazy with lli executable and it solves the problem on Ubuntu 18.04 (still does not work on Windows 10). But this solution is good enough for me now.

Hi Igor, not sure if that will work, but have you tried lli -jit-kind=orc-lazy ? The default is still MCJIT: https://github.com/llvm/llvm-project/blob/master/llvm/tools/lli/lli.cpp#L88 On 13/01/2020 19:07, David Blaikie via llvm-dev wrote: > (+Lang for JIT/interpreter questions) > > On Sun, Jan 5, 2020 at 5:00 PM Igor Gomon via llvm-dev > <llvm-dev at lists.llvm.org
