Hi Nicolas, I plan on using the Avian GC (which is a precise, generational collector). Eventually, I'd like to fully integrate all of the runtime services Avian provides - even integrating the existing Avian JIT compiler, to allow for partially-AOT builds. Avian does indeed have it's own class library, but I would be very surp...

...are 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, to do aot compilation, Avian runs its (completely non-optimizing, but blazingly fast) JIT over all the methods in the selected classpath, and stores these methods in a bootimage, which it links statically with the main Avian executable. All...

Hi Joshua, > I'm trying to use the Java front-end (which, based on svn commits, appears > to be three-years-dead), > I'm trying to use llvm as a replacement aot compiler I'm not acquainted with the Avian JVM, but haven't you considered using VMkit llvm project, it contains .class/.jar to llvm compiler, also JIT compiler(native code compiler) and aot compiler.

Hi Joshua, What plans did you have for GC? No GC at all or Avian JVM has its own GC (and is it precise or not?)? If you're not planning on using VMKit's GCs, then 64-bit system should not be a big problem: the only problem that we have now is compiling GNU Classpath, and most probably Avian JVM has its own version of the class libraries? Also, note tha...

...ime 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: I'm trying to use llvm as a replacement aot compiler for the Avian JVM (see oss.readytalk.com). I figured I may be able to complete the java front end, and sufficiently parameterize it to be used with Avian (which will essentially just provide runtime services like GC and exception handling). Sincerely, Joshua Here is the output of the build (after ./configure)...

Hi Nicolas, Thanks for all your help, but if 64-bit systems are still a big problem, perhaps the VMKit AOT compiler is not the best solution to my problem. I'd like to be able to support the major (if not all all) platforms that the Avian JVM supports - x86 & x86_64 linux & windows, powerpc darwin and ARM.

Jeremy, This has nothing to do with LLVM or VMKit... but if you're interested: I've been working on a light-weight JVM called Avian ( http://oss.readytalk.com/avian/). It has a fast JIT compiler (that produces moderately good code, but no optimization). It doesn't have any .NET support currently, but given the deep similarities between .NET and Java, I think it wouldn't be a monumental task to add support. I've b...

Any idea how can I do this?

R-users, Background: I took roadside samples of avian species richness and I would like to model the relationship between species richness and habitat around my 500 + sample locations (in a file called ROADSIDE). However, one criticism is that roadside habitats do not represent habitats throughout the study area. I tend to disagree because I detect b...

Hello, I am wanting to use MRF to do multivariate regression. We are testing whether acoustic indices can predict structure (relative abundances) of vocalising avian community in UK and Ecuador. There are 26 acoustic indices, 65 UK species and 95 Ecuadorian species. I want to build a model for each ecozone (UK/ EC) using all species (relative abundance) as response matrix, and acoustic indices as predictors. I?d then like to know: - total variance explained &...

Hi Joshua, If you can get a running 32bit system, I'd suggest you do so, as you'll get up to speed right away. I can't test VMKit on a 64bits machine, and I have been aware that there are some compilation/execution problems. Besides, the current GCs of VMKit do not work on 64bits (neither MMTk nor GCMmap2).
