The source pane may display either high level source code alone or source code interlaced with disassembly instructions. The interlaced view shows you the machine instructions that correspond to each source line.
To get an interlaced view, do one of the following:
When assembly code is displayed, the address, in hexadecimal, of each assembly instruction is shown in the source pane. When the program stops at a line in the high-level source code, the PC pointer is placed at the first assembly instruction associated with the high-level source line. Not all high-level source lines generate executable code.
To set a breakpoint on an assembly instruction, click the breakdot.
If no high-level source code is available or if the module was not compiled with debugging information (the -G or -g option in the compiler), the debugger will display assembly code only.
When viewing only assembly code in the source pane, you can scroll through all of memory in either direction. In this mode, you cannot drag the scroll thumb. See "Infinite scrolling" for more information.
