similar to: [LLVMdev] program specialization vs LTO in LLVM

Hi, I am considering using LTO in LLVM for optimizing a domain specific language. What are main advantages and disadvantages of using LTO in LLVM over a compile time approaches such as partial evaluation and program specialization.

Hi Chris, Thanks for pointing me to that presentation! It helped me come up with a strategy that I believe might work: 1) Use CloneFunction() to make a copy of the original unspecialized (but optimized) function. 2) Specialize it using a custom function pass which identifies the specialization parameters and substitutes them with given run-time constants. 3) Run the function through a

I don't think there is any infrastructure for this kind of specialization. The closest thing I can think of is the profile-guided optimization stuff that Andreas Neufstifter has worked on. Because compilation and optimization with LLVM is expensive, our approach with Unladen Swallow has been to try to wait longer to generate specialized code, so we don't have to recompile. If memory

Hi all, I'm attempting to use LLVM for run-time code specialization, but I'm facing a performance hurdle. I'm currently performing the specialization during the AST to LLVM IR translation, but unfortunately this leads to relatively slow recompiles as LLVM has to perform all the heavy (optimization) passes over and over again. So I was hoping that by first creating unspecialized LLVM

I've just hastily migrated from Dovecot 1.2.9 to 2.2.9 due to a disk crash. When I say hastily, I literally copied the user's mail data files to the new server and then started the Dovecot service. The trouble is, I now have a user who can see all the subfolders of her inbox in Outlook, but not on her iPad. Do I need to re-index her mail folders? The data is there (as seen by Outlook

Hi all, I'm looking at using LLVM to do some dynamic transforms of code, and was wondering if someone could comment on the current status of how LLVM handles function specialization, in particular how it updates/rewrites existing (previously emitted) code (possibly rewriting stack of currently executing threads as appropriate). Does anything like this already exist? Are there projects that

Hi, I have a question regarding ExecutionEngine on multicore machines. Say I have n different Function objects that I want to execute simultaneously on a multicore machine. So, one would want to create n different instances of ExecutionEngine and run each function. But, if I understand correctly, there can only be one instance of ExecutionEngine, so there would have to be a locking mechanism

Thanks for the detailed response! :-) > This is by design. LLVM's type system is very low-level... Yes, and it should remain low-level. :-) > Expecting it to directly support generics seems a third-order-of- > magnitude leap of faith. :) But there is good news for the faithful? Let us distinguish between generics as found in java or .Net, and parametric polymorphism in general.

Hi All, Does anyone know if there's a Samba 4 to Samba 4 migration process? Sounds weird, but it has a logical reason: I've a several-year-old S4 implementation, from an early Alpha (10 I think?) that hasn't been in the best of shape of late - when S4 4.0.0 arrived, I accidentally upgraded using my normal "git pull; ./configure; make; make install" procedure and instead of

As far as I know there isn't anything available for this, but I thought I'd check before working up something of my own. Is there a way to query Amazon SimpleDB and import the data results directly into R? Cheers, Tim.

Hi, How do I link two HTML SELECT''s together. Let''s say for example that I have a drop-down list with a list of all countries. Once the user selects one of the countries I would like to make an AJAX call back to the server to populate the second drop-down list with all of the cities for that country. Any ideas on how to go about to do this? Regards Jerrie Pelser --
