Solved... For the record, there were two issues: 1) I was not passing the Function to getAnalysis for the PDT. 2) I was attempting to getAnalysis on external functions.

The only Transforms check that fails is LLVM :: Transforms/GVN/null-aliases-nothing.ll Could that be related?

To be more specific, it would be helpful to have some utilities for finding dependencies (true, output, and anti-). Where is a good place to start for this kind of analysis?

I have written a module pass. When I use the debug pass structure option, the name of my module pass is printed but then I get "Unnamed pass" when the FunctionPassManagerImpl *FPP calls dumpPassStructure (in PassManager.cpp). Is this the expected behavior, or should I be concerned that there is an error in my approach? Thanks, Scott

I want to be able to detect reduction operations using a method similar to that described here: http://portal.acm.org/citation.cfm?id=237578.237581 (I am open to other suggestions if there is a better technique). I am curious if anyone has done this with LLVM or if there are and recommendations for where to start with my implementation. I am only interested in identifying the reductions -- I

Hi all, I recently experienced the same issue as below with LLVM 2.8 on Mac OS 10.5.8. I can load the pass with the debug version of opt, but not the optimized version. Does anyone know what the problem is or have any suggestions for debugging this? My install went fine except for some failures during make check (Unexpected Failures: 92). All failures were in one of the following:

Is there a way through the Value class to get the identifier for an unnamed temporary? Or alternatively, could someone point me to the code where temporaries are assigned sequential numbers as identifiers so I can better understand this issue? Thanks, Scott

Ah, nevermind... just needed to make clean to clear out some of the junk I compiled with gcc-4.1.2. The build completed without error.

I am attempting to install llvm on CentOS 5.3, which uses gcc-4.1.2 as its system compiler. Since this compiler has reported to behave poorly with llvm, I built gcc-4.2.4 in an insulated directory for use with my llvm installation. However, I am not sure I am configuring properly. The gcc-4.2.4 installation is in /pkg/bin/gcc-4.2.4. Here is my config line: ../llvm-2.5/configure

Hello, I just built a virgin ToT (r98634) for release on vanilla Snow Leopard.
