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. The preliminary results of Polly compiling overhead is listed as follows: Table 1: Compiling time overhead of Polly for PolyBench. | | Clang (econd) | Polly-load (econd) | Polly-...

...itten a pass able to analyze the code and see if functions in a module are pure. I managed to run the pass with opt -load on a simple (single file) program IR (generated with clang). Now I am willing to run it on a structured program (probably on a benchmark suite like: http://euler.slu.edu/~fritts/mediabench/) to see how many pure function are identified and how many time it takes to perform the analysis (similarly to the -time-passes option). Do you have any suggestion on how to do it? Thank you in advance, Niko -------------- next part -------------- An HTML attachment was scrubbed... UR...

Hello, all When I compile mpeg2enc of Mediabench, it seems clang and llvm take longer time than gcc. I meausre the time as follow: gcc -O3 8.190s clang -O3 20.253s will this means clang and llvm are slower than gcc in compiling c code.

Hi, Question I had was if someone has tried executing Mibench or Mediabench benchmarks using llvm. I am trying to do simple qsort benchmark in the Mibench benchmark suite. I substituted llvmc instead of gcc in the makefiles. But I am getting the following error. "llvmc qsort_small.c -O3 -o qsort_small -lm llvmc: Configuration file for 'c' is not available. m...

There is actually only one hardware, but with a lot of so called "profiles". For example, there are totally 32 hardware registers available, but the three profiles, namely: * Low register usage profile - use 8 registers at most * Medium register usage profile - use 16 registers at most * High register useage profile - use 32 registers at most I could define a "TablGen target"

Hi, I need help debugging a problem a problem that only shows up on PowerPC with one of my commits in the generic CodeGen parts of llvm. I'd apreciate it if someone with access to a PowerPC system could take a look at this: https://reviews.llvm.org/D23097 <https://reviews.llvm.org/D23097> - Matthias -------------- next part -------------- An HTML attachment was scrubbed...
