[LLVMdev] LLVM GDB : Function "llvm::PassManager::run" not defined.

[Manideepa Mukherjee]

Hi,
I am following the llvm documentation for debugging my pass from
http://llvm.org/docs/WritingAnLLVMPass.html. But when I am  trying  to
break the pass manager and run I am getting the following messages.

(gdb) break llvm::PassManager::run
Function "llvm::PassManager::run" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (llvm::PassManager::run) pending.
(gdb) run /home/manideepa/Desktop/research/compiler/testing/matmul.bc -load
../lib/loop_graph_analysis.so -loop-graph-analysis
Starting program:

"/lib64/ld-linux-x86-64.so.2" (CRC mismatch).

This is inadvisable as it may cause display problems. If
you REALLY want to taste LLVM bitcode first-hand, you
can force output with the `-f' option.

Please help me and suggest me how to debug my pass
