--- Comment #2 from sandra at gcc dot gnu.org --- I've picked up this issue again (after almost 10 years!) because it continues to annoy me how hard it is to find information in this chapter unless you already know what to search for. A problem I've run into with adding sections for grouping is that Texinfo provides a fixed set of sectioning commands with the deepest being @subsubsection. And, we already have dozens of @subsubsections in the various target-specific attribute and builtin sections, so adding another level in the obvious way seems impossible. I could change the existing @subsubsections to @subsubheading, but that would remove them from the table of contents. For now I'll work around that problem by focusing on moving other sections around and leaving those things alone for now -- any incremental improvements to this chapter would be worthwhile even if they're not perfect, IMO.
