It seems the GVNPRE pass has been removed from the main trunk, though it is present in the 2.6 release. From the llvm-commits archive, I found that it was removed  with this checkin: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20090928/088214.html "remove the GVNPRE pass. It has been subsumed by the GVN pass." Does the GVN pass optimize all the partial redundancies

Hi Daniel, Got it. If that's the case, can I implement it under the guidance of your insights/prototype? I think I can spend more time on implementation.

Hi Daniel, Thank you for your detailed reply, and thank you for working on GVNPRE. I’d more than happy to test/evaluate it with our benchmark once it is ready. Please let me know if you need any help.

i wish to develop llvm SSAPRE compiler optimization for my engineering academic project .for,that i have a sample c++ program and its .ll file.anyone have SSAPRE implementation in c++. if anyone have, please give me that implementation immediately. joseykollam at gmail.com josey @ 9895685353 elw technologies cochin -------------- next part -------------- An HTML attachment was scrubbed...

The GVN algorithm used in LLVM currently (I'm rewriting it) is the basic hash based RPO algorithm. The new one i'm writing is based on http://dl.acm.org/citation.cfm?id=512536 (see https://github.com/dberlin/llvm-gvn-rewrite) LLVM has different algorithms for both scalar PRE and load PRE. They are basically variants of standard PRE algorithms transformed into SSA, but with some

Hello, In some of our internal benchmarks, I observe that LLVM performs worse than GCC because LLVM fails to perform PRE when GCC can. I hope this problem goes away when NewGVN equipped with PRE, and wonder if anyone has an idea about the status of PRE on top of NewGVN. Thanks!

Google's SoC is becoming a huge program, and I expect we'll get a few students wanting to do LLVM projects. (I already got one and asked him to write to llvmdev.) Is there anyone who can volunteer to put up a simple set of guidelines for LLVM SoC projects? (That will also get LLVM noticed by anyone searching for SoC.) It can be modeled after (but much shorter than) GNU's

Hello everyone I am Rakshit Singla, a third year undergrad at IIT Hyderabad, India. I finished a basic compilers course last semester and am currently doing a compiler optimizations course. I have been exploring LLVM for the past few months (wrote a front-end for the Classroom Object Oriented Language and have been studying pieces of code.) I would like to work with LLVM and contribute to the

All, I'm pleased to announce that Xiph.org has been selected as a mentoring organization for the 2006 Google Summer of Code program. So if you need a summer job, and there's something about free multimedia that's been bugging you, here's your chance! We've put up some project ideas for things we'd like to see in the wiki http://wiki.xiph.org/index.php/Summer_of_Code
