Oh, I see. For reduction and induction, you don't need to deal with
the condition with vdef. I am considering how to implement an idiom
with vdef, like SCAN (prefix sum). And by the way, do you support
idioms with vuses?

Just curious - what is this for? (are you interested in this in the context
of vectorization? is there a specific example you have in mind?)

Thanks! In fact, I should ask how to deal with idiom (such as
reduction, induction) recognition for virtual defs/uses.

Hi,
I am reading the code of autovect branch and curious about how to deal
with the dependencies of virtual defs/uses. In the function
vect_analyze_scalar_cycles( ), I found the statement "Skip virtual
phi's. The data dependences that are associated with virtual defs/uses
( i.e., memory accesses)
