[LLVMdev] How to describe a pointer that points to All memory(include global memory, heap, stack)?
Hi, John
I am building a flow sensitive intra-procedural alias analysis(without interprocedural info).
So, the first thing I have to consider is where a parameter-pointer or a global-pointer might point to.
Then I defined several special Virtual Memory Locations: ALL_MEMORY, GLOBAL_MEMORY, STACK_MEMORY, HEAP_MEMORY. ALL_MEMORY contains GLOBAL_MEMORY, STACK_MEMORY, HEAP_MEMORY.
e.g1:

Hi, Daniel, thank you for your advice.
Yes, ALL_MEMORY points to ALL_MEMORY.
We use MD(memory descriptor) to abstract a memory location.
MD contains 4 main fields: id, base, offset, size.
For these special MD (ALL_MEMORY, GLOBAL_MEMORY, STACK_MEMORY, HEAP_MEMORY),
we give them id 1, 2, 3, 4, that means MD1 is ALL_MEMORY, MD2 is GLOBAL_MEMORY, the same goes for the rest.
Then we maintain a

Without any context, your question is difficult to answer. Are you
building a points-to analysis and wanting to know how an alias analysis
might encode the fact that a pointer could alias any other pointer?

[LLVMdev] How to describe a pointer that points to All memory(include global memory, heap, stack)?
Hello, could any one point me following question.
e.g:
void foo(int * p)
{
*p = 0;
}
Here 'p' may point to all memory location.
Could you tell me how to represent the POINT TO set of 'p'?
Here is my solution:
Introduce a memory-class named: Global_Mem, then p pointed to global_mem.
And the MOD set of '*p=0' is
