Thanks! > This would be a great addition to gcc internals documentation. > Especially if you could click on each pass and get to a description. This would be good. However, looking at, say, http://gcc.gnu.org/onlinedocs/gccint/Tree-SSA-passes.html#Tree-SSA-passes I don't see meaningful per-pass anchors there. I'm not familiar with gcc's documentation toolchain; is there a way to add the necessary anchors to the generated HTML? (I assume that that page and its sisters from http://gcc.gnu.org/onlinedocs/gccint/Passes.html are the canonical documentation on each pass). (FWIW, currently all I have at the python end is the "name" field of the plugin; I don't have the C identifier of the function that implements the pass - though perhaps that could be scraped at plugin build time, which would of course be ugly) Dave
