I figure (hopefully correctly) that I can iterate over all pool descriptors in a program by iterating over all users of poolinit and looking at the first argument. However, once I have a pool descriptor, I need to get its corresponding DSNode in the function in which it is complete (or in the global graph if it is a global). How do I do this? Thanks, --Patrick

Thanks for all your help so far. My problem is that what I have are the pool descriptors, which I by traversing the uses of poolinit and accessing the first argument of each call. I need to find the DSNode (in the original function) to which this pool descriptor corresponds. The rub is that this pool descriptor of course does not exist except in the clone. If I call getFuncInfo(), I get a NULL pointer. getFuncInfoOrClone(...

Harmen, your suggestion of inverting the mapping almost worked (and Andrew was correct that the function I need is the same as the one in which poolinit appears). Unfortunately, it appears that this mapping only considers the original function and not any of its clones. Since the pool descriptor in question may very well only exist in a clone, I can't use this. Is there another way? Thanks, --Patrick Harmen van der Spek wrote: > You...

You might want to have a look at PoolAllocate.h. Per function, a PA::FuncInfo structure keeps track of all DSNodes that should be pool allocated. ArgNodes contains pool arguments, NodesToPA contains nodes that are locally pool allocated and thus initialized using poolinit. PoolDescriptors contains a mapping from DSNodes to pool descriptors, and you could easily invert this mapping. Finding a corresponding DSNode which is complete is not uniquely determined. For example, if a function F uses a pool, but its DSNode is incomplete, it might be called from two differe...

...nyway, this was just a thought, I've not really tried anything like that.

Thanks Chris! That was causing me some confusion. Now it's producing a more meaningful output: poolinit((&l2_GlobalPool), 4u, 4u); poolinit((&l2_GlobalPool1), 4u, 4u); l5_tmp_2E_0_2E_i = poolalloc((&l2_GlobalPool), 4u); l6_tmp_2E_7_2E_i2 = l1_makeList((&l2_GlobalPool1), 0); *(&((struct l_struct_2E_list *)l5_tmp_2E_0_2E_i)->field0) = l6_tmp_2E_7_2E_i2; However, if I am...
