I think the closest LLVM has is either
Module::getIdentifiedStructTypes or the class it actually uses:
"TypeFinder". Beware though, struct types may not have a name, and
even if they do it won't necessarily correspond to the original C or
C++ name in any meaningful way.
These both return an std::vector<StructType *> in some form, which you
can prob...

llvm extract struct elements and struct size in C++
LLVM Newbie here. I have the following C++ program
using namespace std;
struct A{
int i;
int j;
};
int main()
{
struct A obj;
obj.i = 10;
obj.j = obj.i;
return 0;
}
Using clang++, I can see that LLVM IR contains struct field as below
%struct.A = type { i32, i32 }
I would like to obtain the structure elements using LLVM Pass. I write
the following program - that iterates

RFC: EfficiencySanitizer Cache Fragmentation tool
...===========
We focus on two ways to get cache fragmentation information:
1.
Struct field access patterns.
2.
Heap/global object access patterns.
=====================
Struct field access patterns
=====================
1.
Get all the struct type information (e.g., via
getIdentifiedStructTypes()), and create a counter for each field of each
struct.
2.
Instrument each GEP (GetElementPtr) instruction if it operates on a
struct type to update the corresponding field counter.
3.
At the program exit, filter and sort the struct field reference
counters, and print the str...
