11// This simple program is to test the lldb Python APIs SBTarget, SBFrame,
12// SBFunction, SBSymbol, and SBAddress.
13//
14// When stopped on breakppint 1, we can get the line entry using SBFrame API
15// SBFrame.GetLineEntry().  We'll get the start address for the the line entry
16// with the SBAddress type, resolve the symbol context using the SBTarget API
17// SBTarget.ResolveSymbolContextForAddress() in order to get the SBSymbol.
18//
19// We then stop at breakpoint 2, get the SBFrame, and the the SBFunction object.
20//
21// The address from calling GetStartAddress() on the symbol and the function
22// should point to the same address, and we also verify that.
