It looks like a reasonable first version, but it obviously needs to be extended for the final application. I would also recommend to install Polly and try to find the first test cases that cannot be handled. Some comments to your

Hi. I see that to detect scops firstly we search for regions in CFG ( by RegionInfo ) and then select regions that answer some requirements ( in ScopDetection ). Because only affine expressions in conditions and bounds are permissible, we trying to get scalar expressions into affine form by AffineSCEVIterator. At present there plugs for scev types Truncate, ZeroExtend, SignExtend, UDivExpr,

Hi I've tried to get doxygen documentation by configuring with --enable-doxygen. Then 'make install' has been interrupted with message "error: configuration file /media/data/virtual/share/gsoc/build/docs/doxygen.cfg not found!". mikem, why did you remove a line "AC_CONFIG_FILES([docs/doxygen.cfg])" in autoconf/configure.ac [1] ? I've restored this line. Now

Hi, I'm using Polly to analyze memory access patterns for an university project and I'm trying to get polly working on some loops that polly marks as "containing non affine branches" . >From what I understand polly skips Scops that contain these branches (which comprises something like "if (i % 2 == 0)" where i is a loop varying variable) because these kind of

Hi all, I have updated my GSoS proposal: "FastPolly: Reducing LLVM-Polly Compiling overhead" (https://gist.github.com/tanstar/5441808). I think the pass ordering problem you discussed early can be also investigated in this project! Is there any comment or advice about my proposal? I appreciate all your help and advice. Thanks, Star Tan Proposal:

Mmm, this code seems to kill polly: #include <stdio.h> #include <stdlib.h> int main() { char *B; int i,j,k,h; const int x = 0, y=0; B = (char *)malloc(sizeof(char)*1024*1024); for (i = 1; i < 1024; i++) for (j = 1; j < 1024; j++) { if (i+j > 1000) B[j] = i; } printf("Random Value: %d", B[rand() % 1024*1024]); return 0; } running: opt

Mmm I found out a very strange behavior (to me) of the SCEV analysis of the loop bound of the external loop I posted. When in ScopDetection it gets the SCEV of the external loop bound in the "isValidLoop()" function with: const SCEV *LoopCount = SE->getBackedgeTakenCount(L); It returns a SCEVCouldNotCompute, but if I change the "if" block inside the loop from: if

Hi Tobias, thanks for the answer. I'll try to give a look to the code you pointed me to , and I'll try to make the modification myself. I'm new to LLVM and Polly, but the code of both seem clean and understandable, so I hope to be able to do it myself. In case I'll ask here for support :) Marcello 2011/10/1 Tobias Grosser <tobias at grosser.es>: > On 10/01/2011 03:26

Hi, A few tests seem broken for a long time, some for more than a month. Would it possible for respective owners to take a look please?
