I can't seem to find a way to do that llvm seems to want all sources in one directory.

...r 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 I want to do is use the llvm code generation in place of the Avian...

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, 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: C...

...ld 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: 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 bu...

...language to 64-bit native, and this has posed a few interesting challenges. The most pressing issue for me now is that stack walking is very different on Win64. It is not immediately clear to me if LLVM (3.8 or ToT) is in a position to enable reliable stack walks. Please note I'm using purely AoT compilation here with a custom linker/binary image emitter. I can sort of hack things up in JITted code using a manual process to populate data for RtlAddFunctionTable but I'm ultimately not interested in JIT code generation. I've managed to intercept data destined for the .pdata and .xda...

...le with this runtime environment, but I'm going to declare those out of scope for the moment, to prevent the discussion from ranging too far afield. At the same time, you'd probably want a few core types (like String) to be standardized. This runtime environment would be mainly targeted at AOT (Ahead Of Time) compiled languages. That is the primary distinguishing feature compared to something like the JVM or CLR. Given that brief description, my questions to the forum are: - Is something like this technically feasible? Or is it too ambitious? - Is this something that people would...

Hi Does anybody use *StartJnjvmWithJIT* from jvjvm.cpp in VMKit? Becuase , I am looking to use without JIT when we are running the Java byte code. My concern is StartJnjvmWithJIT getting three argument *int argc, char** argv, char* mainClass* - why we need to pass *argv and mainclass* arguments here? please help me on this. Regards Sri. -------------- next part -------------- An

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.

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 use a patchpoint to generate a safepoint...
