[llvm-dev] BoF: Shipping Software as LLVM IR (@Upcoming Dev Mtg)
Hi LLVM’ers! We are hosting a BoF at this year's Dev Meeting on a subject we hope will be of interest to some (many?) of you: shipping software (entirely) as LLVM IR. You can find our proposal in the meeting schedule online: https://llvmdevelopersmeetingbay2016.sched.org/event/8Yzq/shipping-software-as-llvm-ir The BoF is scheduled to last 45 minutes, which will go by very quickly! To make the best use of the time, we'd like to get a head-start on some of the discussions, and get a feel for what topics people are most interested in discussing. To start things off, here are a few suggestions for things to discuss. Thoughts -- and suggestions for additional topics -- welcome. * Do you ship software as IR today? What lessons have you learned? * Challenges of shipping software as IR * Representing software: Beyond a single module * From build systems to LLVM IR: toolchains and more * What would you do with a platform where everything was available as LLVM IR? * What tools or infrastructure would help make that happen? (Some background to explain why we’re interested in this topic.) ALLVM: We have a project in our group exploring the benefits of shipping *all* software on a system as IR. We are building a prototype ALLVM system that makes it relatively easy to package and ship software in this way. We are researching the benefits this could provide for performance and for general software development. We aim to make the ALLVM prototype available in open source form to enable other groups to explore these goals. Contact us off-list if you’d like to learn more about the ALLVM project. ~Will (and Vikram) -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I think as soon as you want to have long-lived IR, the bitcode serialization is a corner stone piece of the system. Somehow related, I posted this recently to llvm-dev: http://lists.llvm.org/pipermail/llvm-dev/2016-September/105273.html <http://lists.llvm.org/pipermail/llvm-dev/2016-September/105273.html> ; I’d be interested how we could leverage a better serialization for various use-cases!

Thanks, Alex

Hi Mehdi, Yes, we did see your earlier post. Efficient (de)serialization is definitely important for both exporting (a la LTO and ThinLTO) and for shipping code as IR. I expect most use cases of the latter would benefit. -—Vikram // Vikram S.

My personal opinion is that while incremental improvements can and should be made (e.g., for better vector ISA portability), any kind of general solution is a hard problem and different systems will probably have to adopt fairly customized solutions, as PNaCl and SPIR did, at least in the near future. Since you mentioned it, the hVISC project (recently renamed HPVM) only addresses portability for parallel systems (GPUs, vector hardware, multicore shared memory multiprocessors), but not for scalar code issues such as pointer sizes, endianness, OS APIs, etc., which are also important for use cases like PNaCl and SPIR. -—Vikram // Vikram S.

Hey all! Here are the slides I plan on using during tomorrow's BoF! https://wdtz.org/files/allvm-bof-slides.pdf In addition! We'll be taking advantage of http://slido.com after I saw how useful it was during the git BoF :). You can use this by visiting 'slido.com' and entering the code "#ShipIR", or using the following URL: https://app.sli.do/event/nxp6ayku We'll be using this to ensure the discussion addresses the questions/topics that are of interest to the community, so please add your topics and vote on what you'd like to discuss! You can do this during the BoF as well :). Thanks guys, see you tomorrow! ~Will On Fri, Oct 14, 2016 at 1:32 PM, Will Dietz <wdietz2 at illinois.edu> wrote:> Hi LLVM’ers! > > We are hosting a BoF at this year's Dev Meeting on a subject we hope will be > of interest to some (many?) of you: > shipping software (entirely) as LLVM IR. > > You can find our proposal in the meeting schedule online: > > https://llvmdevelopersmeetingbay2016.sched.org/event/8Yzq/shipping-software-as-llvm-ir > > The BoF is scheduled to last 45 minutes, which will go by very quickly! > To make the best use of the time, we'd like to get a head-start on some of > the discussions, > and get a feel for what topics people are most interested in discussing. > To start things off, here are a few suggestions for things to discuss. > Thoughts -- and suggestions for additional topics -- welcome. > > * Do you ship software as IR today?
