This patch updates DbgVariableIntrinsics to support use of a DIArgList for the location operand, resulting in a significant change to its interface. This patch does not update all IR passes to support multiple location operands in a dbg.value; the only change is to update the DbgVariableIntrinsic interface and its uses. All code outside of the intrinsic classes assumes that an intrinsic will always have exactly one location operand; they will still support DIArgLists, but only if they contain exactly one Value. Among other changes, the setOperand and setArgOperand functions in DbgVariableIntrinsic have been made private. This is to prevent code from setting the operands of these intrinsics directly, which could easily result in incorrect/invalid operands being set. This does not prevent these functions from being called on a debug intrinsic at all, as they can still be called on any CallInst pointer; it is assumed that any code directly setting the operands on a generic call instruction is doing so safely. The intention for making these functions private is to prevent DIArgLists from being overwritten by code that's naively trying to replace one of the Values it points to, and also to fail fast if a DbgVariableIntrinsic is updated to use a DIArgList without a valid corresponding DIExpression. |
