Hi Alastair, In addition to your planned tasks, you might want to put in some work to ensure branch probabilities are not lost during optimization. One known issue is LLVM optimizer can turn branchy code into switch statements and it would completely discard probability. Here is a simple example: static void func2(int N, const int *a, const int *b, int *c) __attribute__((always_inline)); void

Hey Xapian guyz, This is my list set of ideas and overview of my analysis I have done on some other ideas I felt should be discussed. Please provide me some comments and suggestions to make it better before the application process starts.

Hi Phillip, I've been looking into the Capture Tracking Improvements and I was wondering if there was any research/documentation that you know of that I could use as background reading? Many thanks, Scott

Hello, I'm a student interested in the syslinux project of Gsoc. And Isincerely hope to have the opportunity to apply the "Dynamic linker/loader for modules" project. But it seems the #syslinux channel is not so active and I can't contact a mentor about that. Could anybody help me? Thank you!

This is a proposal for improving LLVM's support for profile information. Many optimizations can benefit from using that information, especially things like inlining and code placement, but LLVM's current profiling support is not very usable. We should fix that. I've been collecting ideas from other LLVM developers over the last few weeks, and I've put them together here to

Hi, guys I am Wenjin from Graduate School of Chinese Academy of Science, pursing a master degree and my current research interests including using Data mining and Information retrieve technology to analysis software engineering (SE) data and support SE. I have great interested in "Weight Schemes" project. and in the last few days I have learnt some detail about DFR model family by

Hello, I am currently working on LLVM as a placement student for a year and would love to continue to do so after my placement ends. GSoc seems like an excellent opportunity for this. After looking at the open projects page, I would like to propose working on improving coverage reports. http://llvm.org/OpenProjects.html#coverage Is this project ideal for GSoc and if so, will there be a mentor

I would like to see: (1) LLVM testsuite run every night for all targets, target variants and operating systems, for example by using an emulator to emulate targets for which the hardware is not available. The gcc project has a compile farm which might be usable for this, but we would need to ask them if it is ok. (2) Likewise for the gcc testsuite, with results emailed to the nightly test

hi all, As a part of GSoC 2008 project, I am improving the llvm nightly tester. Now I am in the process of understanding the nightly tester source[1] together with its documentation[2](of course which I am planning to improve). I will ask any thing that need to clarify from the list. Thanks! -Rajika [1] - http://llvm.org/viewvc/llvm-project/nightly-test-server/trunk/ [2] -

Hi Everyone, I?m a student in Peking University, China, my name is Xiaobing Liu, I?m interest in Spelling correction project. I think Xapian?s Spelling correction is based on edit distance with trusted dictionary. I have some questions about the spelling correction algorithm. 1. The Spelling correction algorithm depends on which dictionary, the dictionary in inverted index or other

While on the subject of the testsuite, some random thoughts: - show how test results changed from one week and one month ago, and compared to the last release, rather than just comparing with the previous run as now. Good for spotting trends. - fix the testsuite so that buildlogs are really available: I occasionally see that a nightly tester failed the build, and in the message it gives a url

Hi! My name is Gratian and I would like to participate to GSOC 2011. I'm interested in profile-guided optimizations, and I want to implement two optimizations that can bring tangible benefits for most applications: profile-guided function inlining and basic block positioning. Inlining can be greatly improved if we take into consideration how many times the function we want to inline was

Hello, I'm an undergraduate student in the CS department of Aristotle University of Thessaloniki (AUTh). Last year I successfully completed GSoC with Mixxx [1] and this year I would like to work on LLVM. I am interested in "Improving debugging of optimized code" [2]. I have gone through the kaleidoscope tutorial and I've set up a basic dev environment for LLVM and clang.

Hi, sounds like a nice project. Some comments below. > *1.

Another suggestion: a web service that would allow you to submit a test build and it would provide you feedback on deviations from known good for that target. I know a lot of people keep two trees around for this purpose, and I'd personally like to ditch the duplicate if I could. -- Chris On Mar 21, 2008, at 9:22 PM, Rajika Kumarasiri wrote: > Hello every body, > Thank you all

Hi. The following is my idea for Improving Testing Infrastructure for the Google Summer of Code Program. Please do let me know if anything is vague or anything needs to be improved. * A framework which provides abstractions for the different protocols that an application uses, is always helpful in a testing process since a Test Engineer need not bother about the implementation of the Protocol.
