similar to: [LLVMdev] Why I cannot use PgmDependenceGraph?

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<PgmDependenceGraph>() in the getAnalysisUsage(AnalysisUsage &AU) of Hello2.

Why some library functions (such as strcpy,strncpy,etc.) are extended in .bc file? How to keep the originally forms of these library functions in .bc file?

Hi, Chris I get a new PostDominanceFrontier class by combinating the code of PostDominanceSet/PostDominanceTree/PostDominanceFrontier FunctionPasses. It works very well. BTW: Why the PostDominanceFrontier FunctionPasses does not use the formal argument in runOnFunction(Function &)? Does it gets the Function from PassManager? Thank you.

Hi, When I compile httpd-2.0, llvmgcc reports many struct types and macros undeclared, but gnu-gcc can compile httpd-2.0 completely.

Hi I hope to use the getAliasSetForPointer(Value *p, unsigned size), the method of AliasSetTracker class, but I donot known what meaning is the argument "size". May somebody tell me? Thanks.

I can use the interfaces of AliasAnalysis in my pass, but how to specify the underlaying pass of AliasAnalysis is DSAA? Thanks.

When analysing a function "fn", my FunctionPass needs some PostDominanceFrontier information of functions which are called by function "fn". getAnalysis<PostDominanceFrontier>() cannot give the information, because it only gives the PostDominanceFrontier information of "fn", not the PostDominanceFrontier information of functions called by "fn".

The llvm I using is llvm-1.2, its cfrontend should be based on gcc-3.4, the system I using is RedHat Linux 9.0, I desire to compile httpd-2.0.51.

Hi Has anybody tell me how to create some new type qualifies in LVM? A type qualify, like "const" in C, is useful for program analysis. I hope that I can set/get the type qualify of any value in a program analysed. Or, if I could add a property to the value class and set/get the property, it is same to add some new type qualifies. So, I simply insert a "int" private

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... URL:

Xia, LLVM doesn't really use type qualifiers the way you're thinking about it. In LLVM parlance, types are neither const nor non-const, they just define the fundamental nature of a value. However, LLVM fully supports Constant Values (see include/llvm/Constant.h) and constant global variables (see include/llvm/GlobalVariable.h). You might want to read up on the LLVM IR a bit here:

Hi I download the libvorbis-1.1.1 and use the encoderexample.c and decoderexample.c to drive it. The parameters i used is samplingrate: 44.1kbps, channel number: 2, quality :0.4. Now I want to compare it\\\'s complexity with MPEG-2 AAC, but don\\\'t know how to trace into the lib , can you tell me how to do that or tell me how many

Hi Any help is appriatiate. I download the libvorbis-1.1.1 and find it support 2 channels only,is it the truth or i just made a mistake? i think the psychology model is model?,why not use model ?? is it because the patent question?

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

Hi, I got lots of "undefined reference" when building vmkit. Anyone can help to give a solution? I download vmkit with "svn co http://llvm.org/svn/llvm-project/vmkit/trunk/", followed the instructions of "http://llvm.org/svn/llvm-project/vmkit/trunk/README.TXT", and built vmkit on ubuntu 13.10 x64 with sunjava 1.6.0_45 + llvm 3.3 + classpath 0.99 + gcc 4.8.1.

I have checked in 3 new analyses: 1. IPModRef (analyze -ipmodref): This is a Module pass that computes flow-insensitive context-sensitive interprocedural Mod/Ref information for a program. It uses DS Graphs to track mod/ref info for distinct data structures. 2. MemoryDepAnalysis (analyze -memdep): This is a Module pass (but will eventually be a Function pass) that computes a
