[LLVMdev] The nearest basic block being dominated by all used values.

[Zheng Wang]

Hello,

Presumably I have two value v1 and v2 from two different basic block A
and B. Now I need to insert to a printf to print those two values at
the same time.
This means I need to find a basic block to insert such a calling
isntruction and at the same time, the basic block should be dominated
by v1 and v2. Is there any easy way to find such a basic block?

Cheers,
Zheng
