Hello everybody, I would like to know more about runtime & idle time reoptimizer mentioned in the powerpoint presentations about LLVM. Which tool in the LLVM toolchain is responsible for this? Where I can find more details on how reoptimizer is implemented? If someone can let me know any doc or specific source code file to look at, it would be helpful. I have also seen a simi...

Hello, In preparation for the LLVM public release, I've moved the reoptimizer out of the main cvs module "llvm" and into the cvs module "reopt". You can go ahead and delete the lib/Reoptimizer directory from your tree, about which cvs will undoubtedly be complaining to you. If you want to build the reoptimizer, cd into your SPARC tree's "project...

Hi, Sorry for this silly question, but I couldn't find the source codes related to "Run Time Optimization" and "Offline Reoptimizer". As there's few references talking about those two parts except for Chris's master thesis. There's a "Runtime" souce code folder, but the codes under that folder mainly relate to gathering profiling information or runtime gc. Can anybody help me point out those two parts...

Dear experts, Could you please let me know where I can find more information on LLVM runtime optimization and PGO repotimization ? I found 3.5 Runtime Path Profiling & Reoptimization in the paper "LLVM: A compilation framework for lifelong program analysis and transformation". I would like to get some more detailed information and apply it to our code. I am not using llvm -

Hi, I am interested in the JIT compiler of llvm, namely, lli. I want to know more about it, but I found little documentation about it. There are a few paragraphs about JIT in the CGO paper, a list of options dumped from "lli --help-hidden", and a short webpage of lli in the website. But many issues are not clearly described. For example, 1. When JIT is available

Hi List, I am in the preliminary stages of adding a JIT compiler to a sizable Scheme system (PLT Scheme). The original plan was to use GNU Lightning, but 1) it seems to be dead, and 2) LLVM has already done a huge amount of stuff that I would have had to write (poorly) from scratch. At the moment, LLVM seems to be the ideal choice for implementing the Scheme JIT, but there are problems that need

Does anybody know if there is some tool to convert from WHIRL to LLVM? maybe some project under development? a similar project?

Hi Stephen, I confirm your observation. AFAIK the current JIT keeps informations from the module, for example AssertingHandle on Values. It's part of my plan to make the MCJIT independent from Module stuff to allow reoptimizations, or to have multiple copies of JITed functions for one function in the module, but there is a long road to go.

Hi All, I've listed the current topics of interest below, along with some notes on each. We only have 30 minutes so we'll barely scratch the surface of these during the BoF itself. My main aims are for you to meet each other, identify potential areas of collaboration, identify things that I can do to unblock you, and get the ball rolling on some conversations that we can continue on the
