3 // This simple program is to test the lldb Python APIs SBTarget, SBFrame,
4 // SBFunction, SBSymbol, and SBAddress.
5 //
6 // When stopped on breakpoint 1, we can get the line entry using SBFrame API
7 // SBFrame.GetLineEntry().  We'll get the start address for the line entry
8 // with the SBAddress type, resolve the symbol context using the SBTarget API
9 // SBTarget.ResolveSymbolContextForAddress() in order to get the SBSymbol.
10 //
11 // We then stop at breakpoint 2, get the SBFrame, and the SBFunction object.
12 //
13 // The address from calling GetStartAddress() on the symbol and the function
14 // should point to the same address, and we also verify that.
