If executable code retrieval was performed, as described in section~\ref{executableretrieval}, and the view has symbol context available, you will be presented with an additional option, \emph{\faMicrochip{}~Show assembly}. Selecting it will replace the source code view with disassembly of the relevant portion of the program that was profiled.
Machine code instructions jumping to a predefined address will display symbol name of the jump target. If the destination location is within the currently displayed symbol an \texttt{->}~arrow will be prepended to the name. Hovering the \faMousePointer{}~mouse pointer over such symbol name will highlight the target location. Clicking on it with the \LMB{}~left mouse button will focus the view on the destination instruction.

Unlike the source file view, portions of the executable are stored within the captured profile and don't rely on the local disk files being available.
