# Be sure to add the python path that points to the LLDB shared library.
# On MacOSX csh, tcsh:
# setenv PYTHONPATH /Developer/Library/PrivateFrameworks/LLDB.framework/Resources/Python
# On MacOSX sh, bash:
# export PYTHONPATH=/Developer/Library/PrivateFrameworks/LLDB.framework/Resources/Python

# This script collect debugging information using LLDB. This script is
# used by TEST=dbg in llvm testsuite to measure quality of debug info in
# optimized builds.

# Usage:
# export PYTHONPATH=...
# ./CollectDebugInfUsingLLDB.py program bp_file out_file
# program - Executable program with debug info.
# bp_file - Simple text file listing breakpoints.
# <absolute file name> <line number>
# out_file - Output file where the debug info will be emitted.
