[PATCH][PBQP] Provide more information in the debug prints

[Arnaud A. de Grandmaison]

Hi Lang,

 

Based on the feedback from Jonas, and my own experience,  here is a patch
which adds some more information to the graph dumps : previously, we were
only dumping the node ids, and this made the graph and dot representation
not very user friendly nor very useable for debug. With this patch, the node
id is dumped together with the register it corresponds to, as well as its
register class.

 

I renamed dumpToStrem to dump, and moved the dump & printDot methods up to
PBQPRAGraph, because those methods now make use of the metadata information.

 

Does this sound OK to you ?

 

Cheers,

--

Arnaud
