Hi Mike, Sounds like an interesting project. Here's some ideas for you on the LLVM Makefile System. If you haven't, I *strongly* suggest you read the makefile and project documentation (docs/MakefileGuide.html and docs/Projects.html). There is much information there that you need to understand. LLVM is set up so that a single directory builds a single result. Since your source code

Hi Minas, Thanks! I wasn't aware that VMKit had the ability to generate llvm code from .class / .jar files - I thought all of its code-generation capabilities were very closely tied to the VM itself. I'll look into this. The motivation behind this project is to be able to get both the small size and fast startup times of Avian, along with the speed of llvm-generated code. Currently,

Hi all I'm writing a direct llvm backend for gcjx a new java fronted for gcc. I'm now ready to tackle creating the structures to represnt classes I read the gcc 4.0 patches and it seems that the llvm struct is padded and aligned using the info from the gcc tree. In my case I don't have this information. I'm willing to intially let llvm align and pad the struct but its not clear

Hi all, I'm developing a novel language that has historically used LLVM for code generation, behind a custom self-hosted front-end. The runtime for this language offers a garbage collector. In the past I've been on 32-bit Windows where precise garbage collection is relatively straightforward (as long as FPO is disabled). Walking the stack is a simple bit of pointer chasing and some

Can we accept the patch which makes this work? There is a patch in the bug report for the MCJIT case. I'm confused why AOT and MCJIT case would be different but without it the information isn't registered.

Hi, I'm new to VMKit and I'm trying to use its AOT Java compiler but I'm immediately getting an error message which I don't understand. Everything was compiler as suggested in the Getting Started tutorial, using GNU Classpath. I try to run: llcj ../../tools/trainer/Release+Asserts/HelloWorld.class and get the following output: Can not materiale a function in AOT mode.0

Oups, sorry for the mistake, llcj (not llc:)) is not more maintained!

For JITs it would appear that there is a patch needed for some kind of relocations. https://llvm.org/bugs/show_bug.cgi?id=24233 Is the patch really needed? What does it do? I'm not an expert here so asking. On Sun, Jul 3, 2016 at 2:48 AM, David Majnemer via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > > On Sat, Jul 2, 2016 at 5:22 PM, Michael Lewis via llvm-dev >

I followed instructions in this page to setup my environment: http://vmkit.llvm.org/get_started.html My llvm, llvm-gcc, and vmkit are not SVN version.

Hi, I'm trying to use the Java front-end (which, based on svn commits, appears to be three-years-dead), and I'm running into some build errors. In that time did llvm change from building with exception handling and rtti to building without? I remember reading somewhere that llvm code should use dyn_cast instead of dynamic_cast. Do these need to be changed here? A little background:

Ok I see. Of course, at runtime, it's enough for dynamic linking or for deoptimization. However, wmkit acts both as a jit and as an aot. For the aot, it means that I can not use patchpoint and that I should have two different compilation strategy. It's not so difficult, but in this case, I can not use patchpoints to generate gc's stackmap for the aot (basically, I think that I could

Hello, As part of a MSIL (i.e. C#) to LLVM frontend I am currently working on ( https://github.com/xen2/SharpLang ), I would need some help/hint about how to properly design "PInvoke callbacks". Through "PInvoke" mechanism .NET allows you to call C functions, i.e.: C#: [DllImport("libc.so")] extern void mempcy(void* dest, void* src, int size); // declaration of C

Hi! I am going to use non-snowball russian stemmer with Xapian. There is a good one at http://www.aot.ru. I've found that current implementation of Xapian::Stem does not allow it (there is no public interface for Xapian::Stem::Internal). Do you apply patches? Are there any recommendations for writing patches? Regards, Oleg Obolenskiy highpower at mail.ru

Hi Mike, hope you are doing well with the llvm gcjx backend. I am currently writing an llvm backend for a C like language for tracing (like D in dtrace). I am very interested in this area. Do you currently put your work in a repository? (maybe as Tom suggested gcjx.sf.net would be an easy start - since it would not require gcc committer status). I am keen on getting LLVM support for gcj. Maybe we
