I want to make a script where I pick a function call and get every memory addressed that's being either written or read from until the function returns. Honestly I feel like this should've been a feature with break and trace but I just don't know how to do it, it would really save a lot of headache. Thanks in advance

Normally such a list will be so huge it's not useful

but you could use this lua script:

Thank you for the script! It works well for tracking memory addresses.

I noticed that the list can still become quite large and I find myself unable to manage. To make the output perhaps useful, I added a filter to only include addresses that are accessed more than a certain number of times.

I hope this helps if you are a newbie like me

function cleanList()
list = {}
end

function parse(address)
if list[address] == nil then
list[address] = 1
else
list[address] = list[address] + 1
end

return false -- make search continue
end

function printlist(minCount)
local r = {}
for k, v in pairs(list) do
if v > minCount then
local e = {}
e.address = k
e.count = v
table.insert(r, e)
end
end
table.sort(r, function(a, b) return a.address < b.address end)

for i = 1, #r do
printf("%x = %d", r[i].address, r[i].count)
end
end

cleanList()


what I am struggling with is when not dealing with smaller functions. e.g. a fairly complex function that accesses a large number of memory addresses, and then list gets quite overwhelming.

Any recommendation on how to manage this, is quite appreciated.

I am thinking of a few modifications to filter out addresses that are accessed less frequently (a specified number of times).

Please let me know if my thinking is on the right track

To me, it'd more interesting to track variables through a function.
For example, I could say, here, the value is in edx before the call.
Tell me what happened with the value in edx.
(added, subtracted, XORed, converted, put into the stack, used as a multiplier, etc.)
