Hi,
I work for Texas
Instruments. I am in the process of
migrating the breakpoint feature of our non GDB debugger from CDT to
DSF. I am
wondering if the breakpoint feature of our debugger is common with
other
debuggers. If that is the case I am willing to design and contribute a
solution
that fits these debuggers as well.
Our debugger is capable
of creating different breakpoint
types - software line breakpoint, hardware line breakpoint, watchpoint,
event
breakpoint, counter, DMA transfer, stack overflow, trace, etc… Each
device can support different breakpoint types. Furthermore, until a
connection
to the device is established, the supported types are unknown.
The backend generates the
list of breakpoint properties
dynamically base on the breakpoint type and the device type. Even for
the same
breakpoint type, the list of breakpoint properties can be different
base on the
device: hardware breakpoint on a MCU has a different list of properties
than a
DSP hardware breakpoint.
In our current product,
this is how we presented this
backend feature.
Due to the dynamic nature
of the breakpoint types in our
backend, we need a way to list all available breakpoint types for the
current
debug device. We added the toolbar action to the breakpoints view:
Selecting a menu items
will prompt the user to specify
initial properties for the new breakpoint. This is an example of the
dialog for
creating a watchpoint:
The backend can specify
if a breakpoint type is applicable
to a specific view: c-editor, asm-editor, disassembly view, C/C++
project,
outline view. These types will be displayed as a context sub menu in
these
views:
The layout of the
breakpoint properties is controlled by the
backend. We decided a property sheet is most suitable to edit the
property
values:
Is this something that
people would be interested for me to
contribute?
Thanks in advanced,
Patrick
