    like title says, I recently is upgrade my tool to be compatable with llvm-15(used be compatable with llvm-3.6.2). In llvm-3.6.2 I can get GlobalVariable by using api DIGlobalVariable::getGlobal, whose codes have been shown below, but in llvm-15.0.0 it was removed. How can I get GlobalVariable from DIGlobalVariable? Can i just cast the forth operand of DIGlobalVariable to GlobalVaribale like that in llvm-3.6..2?
thanks in advance for helping.
