// This simple program is to test the lldb Python APIs SBTarget, SBFrame,
// SBFunction, SBSymbol, and SBAddress.
//
// When stopped on breakpoint 1, we can get the line entry using SBFrame API
// SBFrame.GetLineEntry().  We'll get the start address for the line entry
// with the SBAddress type, resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress() in order to get the SBSymbol.
//
// We then stop at breakpoint 2, get the SBFrame, and the SBFunction object.
//
// The address from calling GetStartAddress() on the symbol and the function
// should point to the same address, and we also verify that.
