[tcf-dev] Find Symbol by Name, Address, Scope

[<Stefan.Falk@xxxxxxxxxxxx>]

Hi folks!

Since setting breakpoints and displaying register contents are already working, the next step would be to load and display the values of symbols/variables.

I see - from symbols_win32.c - that there are several functions that are dedicated to that task. I was now wondering what the best way would be to implement that for my i8051.

What I already have is a complete information structure of my program containing details like

-       Modules, holding
o       Global variables
o       Functions
-       Functions, holding
o       Start, end address
o       Local variables
-       Variables, holding
o       Location address (RAM, Register)
o       Scope information (in C code)
-       Memory Areas, holding
o       Modules (for faster program counter mapping)

So all that is missing is to integrate that into the agent.

What would the best way to do that? As I have e.g. the exact scope information of a variable it would be fastest and easiest if Eclipse would sent me file:line:scope. I debugged it and what I saw was that either find_by_name or find_by_address was called.

Is find_by_address only called if find_by_name didn't succeed?
I don't really understand either how a name should be enough since there could be thousands of "int i;" declarations spread over a program. With no further information (like scope or PC location) this task seems impossible to me.

So is there a way to get more information from Eclipse like the scope of the symbol?

Thanks and best regards!
