...I'm running it on Kubuntu. Now that you mention it I did have a problem during vmkit setup.

Hi Phillip, I've been looking into the Capture Tracking Improvements and I was wondering if there was any research/documentation that you know of that I could use as background reading? Many thanks, Scott

Hey Scott, There has been quite a lot of research on capture tracking (aka escape analysis) for Java and other dynamic languages. See e.g.: https://wiki.openjdk.java.net/display/HotSpot/EscapeAnalysis http://docs.oracle.com/javase/7/docs/technotes/guides/vm/performance-enhancements-7.html http://dl.acm.org/citation.cfm?doid=320384.320386 Nuno -----Original Message----- From: Scott Egerton via llvm-dev Sent: Saturday, May 28, 2016 5:10 PM To: Philip Reames Cc: llvm-dev Subject: [llvm-dev] [GSo...

...this work, has this proposal been discussed before? Are there any known gotchas which prevented it from being implemented? I've found this file. I'm not sure if it's part of the LLVM distribution, or a branch: https://llvm.org/svn/llvm-project/llvm/tags/Apple/llvmCore-2092/lib/Analysis/EscapeAnalysis.cpp It contains a comment: "Returns allow the return value to escape. This is mostly important for malloc to alloca promotion." I'm using LLVM 2.7.

Hi Nataraj, Which platform are you running on? Did you follow all the steps on vmkit.llvm.org getting started page, especially for GNU Classpath? Thanks!

Hi, I intent to use VMKIT to convert java byte codes to LLVM IR I have installed VMKIT 0.26, on running jnjvm (as ./jnjvm Hello.class) in Release/bin I get the same error irrespective of class content : jnjvm: JavaClass.cpp:469: jnjvm::JavaObject* jnjvm::Class::doNew(jnjvm::Jnjvm*): Assertion `(this->isInitializing() || classLoader->getCompiler()->isStaticCompiling()) &&

Thanks Alysson. Unfortunately, those instructions don't work for me (I followed them exactly using a clean system) -- probably because of the recent changes to the svn heads. After fixing EscapeAnalysis in vmkit to use the updated CallInst.getArgOperand interface I hit the error below. I was interested in using mmtk with the system (as recommended), but that requires a llvm-gcc build (and additional config parameters). None of this works for me despite multiple tries (32bit, 64bit, different dist...

That does exist in head, but strangely enough I can't find any implementation of it? It looks like it was removed when we straightened out value...

Hi Zoe, maybe you've already solved your problem with VMKit configuration, but here you can find a mini-tutorial that I've done to guide people on VMKit installation. http://www2.dcc.ufmg.br/laboratorios/llp/wiki/doku.php?id=afpf Best regards, Alysson On Wed, Jun 30, 2010 at 1:34 PM, nicolas geoffray < nicolas.geoffray at gmail.com> wrote: > Hi Zoe, > > Unfortunately, I

Hi Zoe, Unfortunately, I don't have access to a x64 machine anymore, so I can't test that architecture on vmkit. Could you install a virtual machine on your machine that is x86_32? I know it has been successfully built and ran on x86_32 on different systems. Cheers, Nicolas On Wed, Jun 30, 2010 at 7:49 AM, Zoe Wolk <zoewolk at gmail.com> wrote: > Hi again Nicolas, > >
