[llvm-dev] Get the variable size and count from AllocaInst IR instruction

[Dipanjan Das via llvm-dev]

Let's say we the following: AllocaInst *alloca_inst =
dyn_cast<AllocaInst>(&I) // I = instruction
Corresponding alloca instructions in IR are as follows:

%var1 = alloca [3 x i32], align 4
%var2 = alloca i32*, align 8

How can I have the size and count (in case of array) of the allocated
variables?
