similar to: Best Practices for Cloning A Module

Sorry to resurrect an old thread, but I finally got around to testing this approach (round tripping through bitcode in memory) and it works beautifully - and isn't that much slower than cloning. I have noticed however that the copy process isn't thread-safe. The problem is that in Function, there is lazy initialization code for arguments: void CheckLazyArguments() const { if

You could probably round trip it through bitcode in memory. I think all of the IR cloning functionality assumes that only one context is being used. Even if the serialization isn't efficient as a clone could be, it should give you very high confidence that everything Just Works. :) On Tue, Jun 18, 2013 at 1:16 PM, Andrew Clinton <andrew at sidefx.com> wrote: > I have a

OK. I'm getting out the fireproof suit because it's coming and my hackles have been raised by a number of comments on the list of late.

All, I am currently trying to find a better way to do change management for my puppet code. Currently we have a single Master with two environments (test and prod). Each module has it''s own git repo, as does our node defs and our hiera data repository. The ''test'' environment is used to control the servers used by our devs and QA team, and prod are the actual

I have a Module/LLVMContext that I'd like to clone and manipulate in different threads (each thread may perform different translation / optimization, so they need unique copies). Currently this process has to be locked, since each clone of the Module still refers to the same LLVMContext. Is there a way to clone both the Module and LLVMContext so that the copies can be manipulated

I am developing an R package for internal use, and eventually for public release. My understanding is that there is no easy way to avoid copying function arguments in R (i.e. we don't have the concept of pointers in R), which makes me wary of freely creating chains of function calls since each function call implies data copy overhead. Is the above assessment fair? Are there any good write-ups

Thank you for your help. It's working now. I wasn't aware of the usefulness of the User class. The ValueMapper.cpp's "RemapInstruction()" also helped me a lot to remap phi nodes and metadatas.

Hello there, I have libvirt/kvm installed on a HP DL380 server and it seems to be cloning a template image very slowly, in fact a 50GB image just doesn't gets stuck after 7%. Is there a reason why this might be happening? I've tried the same setup on a desktop and never had this issue. The command and setup is listed below: virt-clone -o template.img -n new-clone -f .../new-clone.img

Hello, I need to design a fairly simple front-end for someone to use an R script system that I've built. My thought was to just use the text based menus available in the base R package, perhaps in some kind of loop. How have other people done this? Any "best practices" that you can recommend?

Please reply-all so that the thread is kept on llvmdev. The LLVM Programmer's Manual has examples of how to iterate over many common structures, such as instructions in a basic block[1]. Other than that, you can check the source code or doxygen[2]. Basically, you loop over the instructions as detailed in the programmer's manual[1], and loop over the operands using User's

Yesterday I cloned one of my VMs and, somewhat implausibly, it took virt-clone something like 8-9 hours to clone the 8Gb disk image... Copying it from the command line took a mere 6.5 minutes. I assume this is a bug, and it's not expected to take this long ;-) This was using virt-clone from python-virtinst-0.500.2-1.fc12.noarch in the virt-preview repository. Tom -- Tom Hughes (tom at

Hi Ali, I assume this is primarily for interrupt function handling? If so, I have a few ideas to bounce your direction if you're interested. -j On Aug 6, 2009, at 3:32 PM, Alireza.Moshtaghi at microchip.com wrote: > I need to perform call graph analysis (after all modules are merged) > to > find which function calls which, and depending on the attributes that > each

Hi, I have an Image model that is attached to a item. The image was uploaded through attachment_fu. Now, I want to reuse the same image for a new item. I tried several tips found online.
