[LLVMdev] difficulty in replicating a sequence of instructions + inserting at a different location -- "instruction doesn't dominate all uses"

[Chuck Zhao]

I am having difficulty in replicating a sequence of instructions (2+, 
with def-use dependencies within) and inserting them at a different 
location.

I have tried a few different approaches (IRBuilder, new Instruction(), 
I->clone(), insertBefore/insertAfter,etc.), all leading to the same 
error msg:
"Instruction doesn't dominate all uses"

The DevList has a few previous discussions on this, but not much of 
hints I can get from there.

Could somebody point me a code template or an existing LLVM source file 
that does similar things?


Thank you very much

Chuck
