[LLVMdev] Debugging using gdb

Hi,

I am trying to debug my llvm pass called -aa-eval-garg11 using gdb. However
I am not able to establish a breakpoint in any function of my pass. I have
compiled my
pass with a debug build and I have also compiled the input file (using
llvm-gcc) with the -g flag. Given below is the exact output.


(gdb) break llvm::PassManager::run
Breakpoint 1 at 0x86be87c: file
/home/engr/cs426/llvm/llvm-2.6/lib/VMCore/PassManager.cpp, line 1558.
(gdb) run pointer.bc -load ../Debug/lib/libMP1.so -basicaa -aa-eval-garg11
Starting program: /home/engr/cs426/llvm/llvm-2.6-x86/Debug/bin/opt
pointer.bc -load ../Debug/lib/libMP1.so -basicaa -aa-eval-garg11
[Thread debugging using libthread_db enabled]

Breakpoint 1, llvm::PassManager::run (this=0xbfffe6f0, M=...) at
/home/engr/cs426/llvm/llvm-2.6/lib/VMCore/PassManager.cpp:1558
1558      return PM->run(M);
(gdb) break llvm::AAEvalTemp::PointsToFunc
Can't find member of namespace, class, struct, or union named
"llvm::AAEvalTemp::PointsToFunc"
Hint: try 'llvm::AAEvalTemp::PointsToFunc<TAB> or
'llvm::AAEvalTemp::PointsToFunc<ESC-?>
(Note leading single quote.)
Make breakpoint pending on future shared library load? (y or [n]) n


Is there some clear mistake in my way of using the gdb ?

Thanks.
Pranav
