[llvm-dev] struct size

[Anastasiya Ruzhanskaya via llvm-dev]

Hello,
I have a code (from example in docs):
%struct.ST = type { i32, double, %struct.RT }
%struct.RT = type { i8, [10 x [20 x i32]], i8 }

; Function Attrs: norecurse nounwind readnone uwtable
define i32* @foo(%struct.ST* readnone %s) #0 {
  %1 = getelementptr inbounds %struct.ST, %struct.ST* %s, i64 1, i32 2, i32
1, i64 5, i64 13
  ret i32* %1
}


I want to identify, that %s is pointer to struct, determine what this
struct is and determine the size of every component? With every component
is more or less ok, but the operand %s is not a struct but a pointer. Is
there a convenient way to track this structure usage in getelementptr?
