So it's a human reading problem, where ddb spat out the command names in order that they were in the in-memory struct, and if I wanted to look over the listing I had to visually scan every one since they weren't in order? > Feel free to propose an alternative implementation; noone's wed to > what's in the tree. Here's a patch for 6.x. The display order for the commands is an interesting issue; it would also make sense to group commands (perhaps alphabetically) by the module that defined them, so that when I added a module all my ddb commands stayed together. The patch I have here will leave commands grouped by module, so it would be relatively trivial to have linker_file_register_ddb add a new kind of dummy command that specifies the module name for the following set of commands. N.B. It appears from the FAQ that attachments are acceptable so I'm sending the patch as an attachment. Apologies if this is incorrect.
