I want to use PgmDependenceGraph pass , but my pass cannot work with PgmDependenceGraph. I tried again in Hello2 pass, and it could not work also. The following is I did with llvm/lib/Transforms/Hello.cpp: 1.insert #include "llvm/Analysis/PgmDependenceGraph.h" in Hello.cpp. 2.insert AU.addRequired<PgmDependenceGrap...

Hi All, I want to build dependence graph for a function for forward slicing. I found the PgmDependenceGraph.cpp in a very old release of poolalloc. But it seems to be gone for long. I'm wondering is there a similar class out there in the current release? Thanks very much! David -------------- next part -------------- An HTML attachment was scrubbed...

I think building an intra-procedural analysis with DSA would be pretty easy. If you...

I want to find buffer overflows from general C programs, a bit like SAFECode :). To quicken the dataflow analysis, I wished to slice operands of character strings from C program using pgmdepgraph, but now, I thought I have to use def-use and use-def chain. Do you think it has any sense? Xia ______________________________________ ע������30��������䣨 http://mail.sina.com.cn/chooseMode.html ��

Hi, Is there a way to use LLVM to build the visual representation of program dependence graph (PDG) of a routine/program? >From looking at https://llvm.org/svn/llvm-project/poolalloc/branches/release_14/lib/DSA/PgmDependenceGraph.cpp, it looks like there is an incomplete implementation of PDG in LLVM. However, when I search within LLVM3.0 package, I don't find the .cpp/h code. So, I also wonder if this code is no longer supported. Thanks!

...denceGraph for all data-dependences on memory locations within each function (i.e., the nodes are Instructions; the edges are data dependences). This pass uses the IPModRef pass to find dependences on Call instructions. It does NOT do any non-trivial array dependence analysis yet. 3. PgmDependenceGraph (analyze -pgmdep): This is an iterator (not a pass) that is intended to enumerate all dependences in a function, including data dependences on memory and on SSA registers, and control dependences. It does not build an explicit graph in order to avoid creating a second representation of...

Hello, I found some code within the pool allocation project to identify parallelizable function calls. Unfortunately the functionality isn't part of the current release of poolalloc (in release 14 it was). My intention is to estimate the parallelization-potential of sequential applications concerning coarse-grained parallelism. Can you tell me... 1. Why are classes of pollalloc, like
