Re: Transforms on SSA form

[John Freeman]

There are documented methods of SSA decomposition.  The naive method is 
a simple reversal of SSA composition:

SSA composition: rename variables (typically by adding suffix), add phi 
nodes
SSA decomposition: rename variables (by dropping suffix), remove phi nodes
The short answer to your question is that there is no C equivalent of a 
phi node.  You simply drop it.

Hope this helps,
John
