Function LLVMGetSwitchCaseValue 

pub unsafe extern "C" fn LLVMGetSwitchCaseValue(
    SwitchInstr: LLVMValueRef,
    i: c_uint,
) -> LLVMValueRef

Obtain the case value for a successor of a switch instruction. i corresponds to the successor index. The first successor is the default destination, so i must be greater than zero.

This only works on llvm::SwitchInst instructions.

See llvm::SwitchInst::CaseHandle::getCaseValue().
