Partly, yes, but also because this information is generated from the generated HTML for the user manuals: gcc, gdc, and gfortran, and it gets used to generate "optionlist", which is a dependency for all of the rest of the "gcc" subdirectory. Doing it automatically would make the generation of the HTML docs for gcc, d and gfortran be a hard dependency early on in the build, which seems to me to be a bad idea - better to have this rarely-changing and non-critical information be regenerated when it's needed, and not impose the requirement to build the HTML docs for all these langs on all builds of gcc. > > If nothing else, can you add a few lines to the commit > message why this can't be/is preferably not done at build > time? The wording here: https://gcc.gnu.org/pipermail/gcc-patches/2023-November/636060.html may be what you're looking for. Maybe that text (or something like it) should go in as a big comment at the top of regenerate-opt-urls.py ? Hope this clarifies things Dave
