Yes, some instructions have no sub-codes and will use the subcodes field for flags. Annotations and such will be discouraged as much as possible. If an attribute is very frequently used and causes significant degraded behaviour in pointer-maps or hash tables, then we can see about adding it somewhere. > 2.

I think you are missing the point. This structure defines the bits needed for representing GIMPLE. All we need is a double-chain of instructions. These chains are embedded inside basic blocks. > 3. Are there fields for more debug information? More debug information? What debug information are you looking for?
