The Call Stack view displays the call history.

To use the Call Stack view, DWARF register mapping must be defined for the architecture and provided in the model.

The loaded application must be an ELF file that contains a .debug_frame section. No other type of debug information is supported for the call stack view. The .debug_frame section must contain valid DWARF debug information that matches the DWARF 2 or DWARF 3 specification. The C compiler provides this information to describe all necessary information to unwind the stack:

  • The stack pointer.
  • How to retrieve the previous frame pointer.
  • All registers that are involved in the unwinding process.

Only the frame section can supply this information.
