Not sure if anybody has noticed: The PoolAlloc release source code extracted from SVN won't even build. I tried it last night, on WinXP/Cygwin, for both the LLVM-2.5 release, as well as the latest LLVM, neither would build -- with compile-time errors. With that being said, I have no idea which LLVM release the current PoolAlloc trunk is checked in with. Could anybody point this out? Or, at

Hi, I'm trying to run the pool allocation pass through opt, and I'm running into problems. It segfaults frequently; for example, it does this when the input is a simple Hello World program: [simmon12 at apoc testcases]$ opt -load /home/vadve/simmon12/llvm/llvm/projects/llvm-poolalloc/Debug/lib/libLLVMDataStructure.so -load

Does this mean pool allocation is using TDeq and not BUeq

I don't really have a specific question, but, as I've been looking through pool allocation and the DS graphs extensively, I wanted to verify that my understanding of the representations used is correct. Therefore, I'm summarizing my understanding below (which, if it's correct, may hopefully be helpful to others). I would appreciate if someone who understands pool allocation

Depending on the value of dsa_pass_to_use, either EquivBUDataStructures or EQTDDataStructures is used. In the case that the top-down DSA is used, information is pushed down to nodes in callees. However, if bottom-up DSA is used, information has only been merged upwards and the nodes are not necessarily equivalent. Harmen Andrew Lenharth wrote: > On Tue, Mar 16, 2010 at 3:46 PM, Patrick

Thanks for all your help so far. My problem is that what I have are the pool descriptors, which I by traversing the uses of poolinit and accessing the first argument of each call. I need to find the DSNode (in the original function) to which this pool descriptor corresponds. The rub is that this pool descriptor of course does not exist except in the clone. If I call getFuncInfo(), I get a

What is this used for? Does DSA put anything here? If I want to add call sites here during my pass, will it confuse pool allocation if it runs afterwards? If so, is there any way I could clear it at the end of my pass? Thanks, --Patrick -- If I'm not here, I've gone out to find myself. If I get back before I return, please keep me here.

Hi, I'm starting to code a pass which uses the analysis results of pool allocation, and I've run into a bit of a snag. Following the advice at [http://llvm.org/docs/WritingAnLLVMPass.html], I've put my new pass in the lib/Transforms subdirectory of the llvm checkout. I have the pool allocation transformation checked out in projects/llvm-poolalloc. My problem is that the pool

Harmen, your suggestion of inverting the mapping almost worked (and Andrew was correct that the function I need is the same as the one in which poolinit appears). Unfortunately, it appears that this mapping only considers the original function and not any of its clones. Since the pool descriptor in question may very well only exist in a clone, I can't use this. Is there another way?

I figure (hopefully correctly) that I can iterate over all pool descriptors in a program by iterating over all users of poolinit and looking at the first argument. However, once I have a pool descriptor, I need to get its corresponding DSNode in the function in which it is complete (or in the global graph if it is a global). How do I do this? Thanks, --Patrick

Hi , This Is 'Suresh M' from AMD compiler team. 1) I obtained the source code of llvm and pool-alloc (relase_32 versions ) using the following commands, svn co http://llvm.org/svn/llvm-project/llvm/branches/release_32 llvm cd llvm/projects svn co http://llvm.org/svn/llvm-project/poolalloc/branches/release_32 poolalloc 2) Was able to build the binaries and libraries

HI guys. I'm trying to build the poolalloc on llvm-2.0 but there exist some errors. Can you tell me which version of llvm is known to make the poolalloc build and install successful?

Hi Patrick, That's right. DSNodes are coupled to the original function. For function clones, you first need to get the original function, and then use the DSNode from that function. FuncInfo contains the information if a function is a clone and what the original function is. If you want to find the corresponding DSNode for some instruction, you must call PA::FuncInfo::MapValueToOriginal(

This is used for unprocessed callsites. Clearing it between DSA
