Hi, I am trying to add alias analysis in llvm. I created a file ProfileAlias.cpp in llvm source at the place where Andersens.cpp is there. ProfileAlias.cpp does nothing at present just empty definitions of required functions. When I build llvm I get the following error: /home/ambika/llvm1/llvm-obj/Release/lib/libLLVMipa.a(ProfileAlias.o): In function `llvm::createProfileAliasPass()': ProfileAlias.cpp:(.text+0x46): undefined reference to `vtable for ProfileAlias' /home/ambika/llvm1/llvm-obj/Release/lib/libLLVMipa.a(ProfileAlias.o): In function `llvm::Pass* llvm::call...

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.

...as: i32* %i.0, i32* %j.0 Is there any other analysis which will give them as must aliases. Actually what I want to do is implement a flow sensitive points-to(not alias) analysis and then use that information for some optimizations like PRE. Will that be possible?

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.

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.

Hi, Suppose I have llvm Instruction as : %9 = load i32* %b, align 4 and I want to extract the name of temporary value used here ie 9. Can any body tell that how can I do that? thanks and regards, Ambika

...asically want is to know that when I run some Alias Analysis then from where the functions of file BasicAliasAnalysis.cpp are called, in which order and which functions does it call while executing, ie the flow of calls in source of llvm. Is it possible to do this. Duncan Sands wrote: > Hi Ambika, try this: > > opt -print-callgraph file.bc > > Ciao, > > Duncan.

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.
