Hi, all I tried Polly installation on Ubuntu. On its building, it returned no errors. But when I run "make polly-test", it returns 11 unexpected failures as follows. ----------------------------------- ******************** Testing Time: 19.77s ******************** Failing Tests (11): Polly :: CodeGen/do_...

Hello Tobi, I am interested in Polly project. Polly seems to be a very promising tool to find out program parallelization based on LLVM infrastructure. However, I find that Polly analysis and optimization can consume significant compiling time, so I propose a GSoC project to reduce Polly compiling time and I hope my work can make th...

Here is an update about moving Polly later. 1. Why does Polly generate incorrect code when we move Polly immediately after the loop rotating pass? It is mainly caused by a wrong polly merge block. When Polly detects a valid loop for Polyhedral transformations, it usually introduces a new basic block "polly.merge_new_and_old&quo...

Dear Tobias Grosser, Today I have rebuilt the LLVM-Polly in Release mode. The configuration of my own testing machine is: Intel Pentium Dual CPU T2390(1.86GHz) with 2GB DDR2 memory. I evaluated the Polly using PolyBench and Mediabench. It takes too long time to evaluate the whole LLVM-testsuite, so I just choose the Mediabench from LLVM-testsuite. Th...

Hi, polly is run very early and schedules the following passes before it runs: /// @brief Schedule a set of canonicalization passes to prepare for Polly /// /// The set of optimization passes was partially taken/copied from the /// set of default optimization passes in LLVM. It is used to bring the code ///...

Hi Tobias and all Polly developers, I have re-evaluated the Polly compile-time performance using newest LLVM/Polly source code. You can view the results on http://188.40.87.11:8000. Especially, I also evaluated our r187102 patch file that avoids expensive failure string operations in normal execution. Specifically,...

Hi Tobias, I am trying to move Polly later. LLVM provides some predefined ExtensionPointTy: EP_EarlyAsPossible, EP_ModuleOptimizerEarly, EP_LoopOptimizerEnd, EP_ScalarOptimizerLate, ... Currently Polly uses "EP_EarlyAsPossible" to run as early as possible. As what you suggested: >Instead of removi...

Hi Tobi, Rick is trying to set up a public buildbot for Polly on Windows. Right now the community version of polly does not build on Windows. We would like to make it possible to link polly statically to avoid several problems dealing with building polly as a DLL. I have a set of changes that make polly link statically in opt, clang, bugpoint, etc. These...
