[LLVMdev] Indirect function call

[Nai Xia]

Hi,

The "LLVM Language Reference Manual" mentions about "indirect function call". 
I am just curious about what exactly is the __syntax__ of them and how I can 
get the callee of an indirect callsite.
>From my point of view, there is hardly any cases where indirect calls are 
needed, because anywhere we use a "fptr" in C, it could just be represented 
in LLVM IR like this: 

%tmp = load void ()** %fptr
call void ()* %tmp( ) 

So what is indirect call used for?
