[LLVMdev] How to describe a pointer that points to All memory(include global memory, heap, stack)?
...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 Global_Mem.
But how to present the overlapping alias set:
e.g2:
extern A[100];
void foo(int * p, int i)
{
*p = 0;
A[i] = 10;
}
'p' may point to anywhere. So p may point to A. Ho...

DLL at fixed location and memory sharing between executables
Is there a way to get the following to work under WINE? (i.e. to get two
executables to share global memory as they do under windows)
We have a DLL that is at a specified memory location.
At the top of the code a variable is declared as follows:
#pragma data_seg( "global_mem" )
#pragma bss_seg( "global_mem" )
unsigned uAttachmentCount = 0;
Now..
The main program links to that DLL and as part of the DllMain it increments
that count.
The main program executes another program. That other program also links
to that DLL.
Under Windows the DLL is loaded i...

[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:
extern int * q;
void f(int * p)
{
int a;
*p = 0; //STMT1
*q = a; //STMT2
}
For above case, both p and q pointed to ALL_MEMORY: p->ALL_MEMORY, q->ALL_MEMORY.
And each STM...

Contains or points to?
ALL_MEMORY should point to ALL_MEMORY, otherwise *ALL_MEMORY !=
ALL_MEMORY, which will break things like linked lists.
In any case, the final representation in GCC of points to a...

[LLVMdev] How to describe a pointer that points to All memory(include global memory, heap, stack)?
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 BITSET class to encapsulate the 'union', 'intersect', 'diff' etc to simply the operations bewteen special
MD and...
