Up to now I have basic support up and running. The hash map to the loop

mentioned it to be necessary to reliably attach data to the loop data
type.
Actually, this is not really MELT specific but also concerns any plugin.
As a general case, most (& probably all) GCC data structures cannot be
extended by plugins. So, for instance, a plugin cannot add its own field
to the loop data. Likewise, another plugin cannot add a field to any
gimple data structure. (More generally, most GCC data are not object
oriented and cannot be extended by plugins).
So plugins (& MELT extensions) have to associate information to existing
GCC data elsewhere. In MELT, there is some mechanism to build hash
tables associating some main GCC data (gimple, tree, edge...) to
arbitary MELT values.
Thanks for your interest in MELT.
Regards.
