[LLVMdev] could you give me some advice ?

hi
I have one llvm program like this :
...
; define ConstantArray
"E1$str" = internal constant [3 x sbyte] c"E1\00"              

; use getPtrPtrFromArrayPtr to define SByte* from ConstantArray 
"E1$entry" = internal constant sbyte* getelementptr ([3 x sbyte]* "E1$str", uint 0, uint 0) 
...

when i want to get std::string object from this declaration in another program

	Module* m = loadModule("XXX.bc");
	Constant* c =  findValue(m,"E1$entry");
	GlobalVariable* gv = cast<GlobalVariable>(c->getOperand(0));
	ConstantArray* ca = cast<ConstantArray>(gv->getOperand(0));
 	std::string str = ca->getAsString();

now str = "E1"
these code looks a little ugly , could you tell me better solution ?
In another word , I want to know the reverse operation of ConstantExpr::getPtrPtrFromArrayPtr .

thanks
