In 0.3 are several extensions to parse attributes, but it seems that <sectionname> isn't stored anywhere. Is it possible to get <sectionname>? If there is no way to get <sectionname> in the actual implementation, i think of an extension in struct ctype. Any comments? Would this be useful for someone else?
Yes, it would be useful. The easiest way is just increase the ctype to include a pointer to section name. The biggest objection is from the fact that symbol/ctype is the most common data structure in the sparse. If we increase the size of ctype, there is a huge impact of the sparse memory usage. I did try to use some kind of extend the attributes. The idea is have the most common attribute embed in ctype. The not common ones will store in a extend attribute structure. The extend attribute structure itself is flat. The initial implementation will only contain address space and context. I found myself keep breaking the existing address space attributes. The attribute propagation not very clear in sparse. Some times we use assignment and some times the attribute is inherited from implicit memcpy and some time we strip the attribute out. I wish to have a more unify way to define how attribute are created and propagate through the ctype, maybe a table or some thing.
