Hi all,
Im writing a pass just before the register allocator in which Im inserting a sequence of new instructions.
I do this by calling subsequently for a number of times BuildMI.
As a result I see that there is a dependency between the produced instructions which shouldnt be there
as the instructions are not data dependent.
Can anybody tell me how to avoid getting the dependency?
thanks,
Alex

What are you seeing that makes you think there's a dependency being formed?
