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.
