// This simple program is to test the lldb Python API SBTarget.
//
// When stopped on breakpoint 1, and then 2, we can get the line entries using
// SBFrame API SBFrame.GetLineEntry().  We'll get the start addresses for the
// two line entries; with the start address (of SBAddress type), we can then
// resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress().
//
// The two symbol context should point to the same symbol, i.e., 'a' function.
