similar to: [LLVMdev] Trying to use patchpoint in MCJIT

patchpoint is intended to be used in VMs that do their own linking, and so you wouldn't expect the function parameter to be resolved by LLVM. Presumably, in VMKit, you could just plant a pointer constant to the function you wish to call initially? -Filip On Dec 17, 2013, at 2:42 PM, Gaël Thomas <gael.thomas00 at gmail.com> wrote: > Hi all, > > I'm trying to play with

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

Hi, Could you tell me if the following is some known issue? While performing the following simple test, I see my JVM crashing (consistently): 1. Open a connection to an ESXi driver/host (passing ConnectAuthDefault instance). 2. Close the connection. 3. Invoke GC When GC is triggered, at some point, some unallocated native memory is being tried to release. That's failing. The error thrown

Note: A couple of times I have seen errors while closing the connection (the trace ending with virFree). Also, a few times I have seen backtraces which show the flow going via esx driver and finally failing to close connection. Unfortunately I dont have those logs anymore. The execution results I have shared have been obtained using Libvirt built from source using the following config parameters:

Did you get a chance to debug the issue?

Hi all, I don't know if I understand everything, but it seems really interesting for a runtime developer, stackmap and patchpoint looks perfect for a lot of optimizations :) I just have few question to verify if I understand what are these stackmaps and patchpoints, and I discuss the GC after. * I have a first very simple scenario (useful in vmkit). Let's imagine that we want to lazily

Hi, I have been trying to install R on solaris 10. i could compile the source files following the steps in R admin.html manual but eventually i don't see the libR.so and libjvm.so file created anywhere. could you please specify me some step by step instructions for installing R in solaris? That would be much appreciated! Thanks and regards, Manjit

Dear list; I have R Version 2.3.1 (2006-06-01) installed on a AMD 64 machine with SUSE 10.1. I have Sun Java version 1.5.0-sun installed. I have used "install.packages("JGR", dep=TRUE) to install rJava, iplots and JGR. I would like to do a presentation of linux and R for the department! Compiling rJava do not give any error messages! But when trying to load

Hi, I've got a problem to use the SJava package with R. I have a SUN solaris 8 machine. Then I did R INSTALL -c SJava_0.65-0.tar.gz without problem Now I try the test provided on the web site: library(SJava) and here I receive the error message: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library

Apologies in advance for the long post. I'm currently using a Makefile to build my shared library. Pursuant to the R-exts manual, I'd like to switch to a Makevars file or a configure file if necessary. Having never used these types of make utilities before, I'm a bit lost. My package is quite simple. It only has one source file and one header: excelpoi.cpp excelpoi.h The reason I

Hi Andrew, hi all, I already saw that the old jit was (almost) deprecated. So, I'm currently playing with the new jit and it's look very interesting. (I'm working locally and I haven't pushed anything new on VMKit because I'm also changing a little the design vmkit). For the moment, MCJIT does not work with VMKit (but I haven't yet tested the safepoint/stackmap patch), I

Hi Andy, Thanks for the answer. I'm currently reading the internal code of MCJIT and it's really a great work (I was only using the ExecutionEngine interface for the moment). So, I agree, all what I need is already in the code (see below) :) 2013/11/14 Kaylor, Andrew <andrew.kaylor at intel.com>: > Hi Gaël, > > Thank you for the detailed explanation. It's very
