Better cross-referencing is one big feature. IMO this subthread has demonstrated why the limitations of info formatting have held back the amount of cross-referencing in the online html. (And based on emperical evidence, I get the impression that far more people use the online html docs than the info docs.) E.g. quoting from Richard's recent patch: @item -fmove-loop-stores @opindex fmove-loop-stores Enables the loop store motion pass in the GIMPLE loop optimizer. This moves invariant stores to after the end of the loop in exchange for carrying the stored value in a register across the iteration. Note for this option to have an effect @option{-ftree-loop-im} has to be enabled as well. Enabled at level @option{-O1} and higher, except for @option{-Og}. In the online docs, this will just be plain text. Anyone who doesn't know what -ftree-loop-im is will have to search for it manually. Adding the extra references to the html (and pdf) output but dropping them from the info sounds like a good compromise. Thanks, Richard
