Hi, I believe shouldHaveNodeForValue() should return false for ConstantPointerNullValue. Fixed in r121707.

AFAIK, all these annotations are more hints than contracts. Adding #pragma omp simd on a loop that has forward dependencies that cannot be solved should not make the loop vec...

Hi, I'm still using the release_26 version of Poolalloc/DSA with llvm 2.6 for my analyses and am currently trying to switch to llvm 2.7 for several reasons. I tried to use the trunk of the poolalloc svn repository with the llvm 2.7 release which is working fine for most of the programs I ran it on so far but for sqlite it's running into a stack overflow since it is endlessly looping in

Hi all, is there any plan when poolalloc and DSA will be adapted to compile and run with LLVM 2.7? I'm currently about to start a bigger project using DSA and it would be nice if I could use LLVM 2.7 instead of porting everything I do now from 2.6 to 2.7 later.

Hi all, I'm running a pretty updated CentOS4 x86_64 server (Still on kernel 2.6.9-42.0.2, but appart from that fully up to date against the official repos) with a USB-disk attached (the USB-disk is a 750G Seagate disk in a Seagate enclosure) over a USB hub. I've noticed several times that after longish periods of activity, the disk drops out (log from last time, below). In this case,

I'm part of a research group at MIT looking to create an extension of LLVM that inherently allows one to nicely code a parallel loop. Most parallel frameworks tend to take the body of a parallel loop and stick it inside of a function for the parallel runtime to call when appropriate. However, this makes optimizations significantly more difficult as most compiler optimizations tend to be

Hi, during the hunt for a bug causing strange behavior of our automatic parallelization framework, I found some, at least for me, unexpected behavior of the DataStructureAnalysis in Poolalloc. Consider the following simplified program: ==================== int ARR[4] = {1, 2, 3, 4}; int a(int pos) { return ARR[pos]; } int sum(int op_a, int op_b) { return a(op_a) + a(op_b); } int

A Proposal for adding an experimental IR-level region-annotation infrastructure ============================================================================= Hal Finkel (ANL) and Xinmin Tian (Intel) This is a proposal for adding an experimental infrastructure to support annotating regions in LLVM IR, making use of intrinsics and metadata, and a generic analysis to allow transformations to

Hi, I'm using DSAnalysis in order to get some points to information. In my particular case for a CallSite. Everything is working well except for some special cases. Consider the following example code: // ====================== void m(short *s) { return; } int main() { m(0); } // ====================== The call to method m in the main method is translated to

Greetings! Just joined the list, after looking at the mail archives and such. I have a few SunFire X4100s on the way, and I was wondering if anyone here has ever ran CentOS in a cluster environment? (I'm looking in Oscar's general direction.)
