hi ambika, I am not sure about this solution as i just started working in this field. How about taking analogy of a problem which ask us to find nearest common parent of two nodes in a tree. Let me know if I can be corrected. - Anubhav intern IIT M B. Tech 4th year CSE VIT University, Vellore. On 31 May 2010 22:30, <llvmdev-request at cs.uiuc.edu> wrote: > Send LLVMdev mailing list

I have done that. I have defined createMyAnaPass() in Passes.h and it is defined in MyAna.cpp and used in LinkAllPasses.h But still the error : /home/ambika/llvm/llvm-obj/tools/opt/Release/opt.o: In function `global constructors keyed to opt.cpp': opt.cpp:(.text+0x1e89): undefined reference to `llvm::createMyAnaPass()' I dont understand whats the problem.

We can do what scalar optimizations do. All scalar passes

llvm itself is a plain C++ program, so you can use gdb on it. gdb doesn't know how to step through compiled IR, yet.

Thanks that helped me out. But now I am facing one more problem. It says : ‘llvm::ModulePass* llvm::createMyAnaPass()’ should have been declared inside ‘llvm’ but I can find no place to declare it. Where should I do it. John Criswell wrote: > ambika at cse.iitb.ac.in wrote: >> Hi, >> >> I am trying to add a pass inn LLVM, and I actually want to add it in >> source

Actually I am interested only if the information merges at join node, otherwise not... So just getting a node with more than one predecessor might help. But can I figure out if there is a function call in between, in any of these nodes? Thanks a lot for helping out...

Hi, I used the following commands on the program attached below: llvm-gcc --emit-llvm main.c -c -o main.bc opt -ipconstprop main.bc -o main1.bc diff main.bc main1.bc no difference was o/p :( The Program Segment is as shown below: #include <stdio.h> void f1(int a) { a=a+1; printf("%d",a); } void f2() { int b; b=1; f1(b); } int main() { int

But this is already present in my pass. And I am not able to understand the cause for the error: opt: /home/ambika/llvm_3/llvm-2.6/include/llvm/PassAnalysisSupport.h:203: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*) const [with AnalysisType = llvm::DominatorTree]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not "

Sir/Ma'am, I am a MTech student at IIT Bombay, doing my thesis in compiler optimization. I am working on "Profile Based Pointer Analysis to Perform Optimization", and would like to implement the optimization in llvm for performing experiments. When I was trying to build and install the compiler after configuring llvm-gcc I got the following error: gcc: gengtype-lex.c: No such

Hi, I am trying to add a pass inn LLVM, and I actually want to add it in source code, not just directly into object code. For that I included the lines in my file MyAna.cpp (llvm-2.6/lib/ana/MyAna.cpp) char MyAna::ID = 0; static RegisterPass<MyAna> X("my-aa","My Analysis"); static RegisterAnalysisGroup<AliasAnalysis> Y(X); ModulePass *llvm::createMyAnaPass() {

Hi Ambika, Could you check if you have bison and flex installed on your machine?

Hi, you need something like this in your pass: void YourPass::getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<DominatorTree>(); } because you need to specify which analysis you are using. Tobi
