[LLVMdev] Stable release of pool allocation?
I've been attempting to write my pass (which depends on DSA and pool allocation) against the SVN trunk of LLVM and the llvm-poolalloc project. However, I was thinking it might be better to use the latest stable releases of these codebases. I know that this is the 2.5 branch for LLVM, but are there any stable releases of pool allocation? If so, would there be any disadvantage to my

[LLVMdev] DSA: AuxFunctionCall
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.

[LLVMdev] Pool Allocation Segfaulting with opt
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

[LLVMdev] Getting the DSNode from a Pool Descriptor?
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

[LLVMdev] Getting the DSNode from a Pool Descriptor?
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

[LLVMdev] Stable release of pool allocation?
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

[LLVMdev] Getting the DSNode from a Pool Descriptor?
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

Does this mean pool allocation is using TDeq and not BUeq

[LLVMdev] Building APA
Hey, I think I might be having a build problem. I says here [https://agora.cs.illinois.edu/display/llvmgroup/Automatic+Pool+Allocation] to load LLVMDataStructure.so and poolalloc.so when using "opt" to perform pool allocation. However, I don't have poolalloc.so -- only poolalloc.o. Does anyone know why this might be? --Patrick

[LLVMdev] Question about using steensgaard's pointer analysis in poolalloc
Hi LLVM dev team: I am now doing an experiment to comparing Steensgaard-style and Andersen-style pointer analysis on LLVM. Since steensgaard pointer analysis is in module "poolalloc", so I installed poolalloc release 2.6 on my machine(intel X86_64 RedHatEnterpriseLinux 5.1, gcc-4.2.4), two directories "include" and "lib" were created after installation but no

[LLVMdev] Question about using steensgaard's pointer analysis in poolalloc
Hi, LLVM dev team: Thanks for your suggestion, I have done the experiment to compare the two pointer analysis(Andersen and Steensgaard) methods in LLVM, but the result was unexpected. In each test, I compare these two methods using same optimization; There are several tests, each with a different optimization. The benchmark is all the 11 C programs in CINT2000 of SPEC. In all the tests, I found

[LLVMdev] function pointer alias analysis
Hi I see when LLVM builds the CallGraph SCCs. a function calling through a function pointer is conservatively assumed to call internal and external functions. Therefore, it has an edges pointing to the externalnode2, ie. the externalnode representing outgoing calls from this module. does LLVM have any function pointer analysis capabilities in the mainline ? Thanks, -Trent

[LLVMdev] Alias Analysis (Andersen pointer analysis)
Thanks Everyone for the info. I am planning to work with DSA on llvm-2.9. Hope it is working as John mentioned.
