ISTR it was awkward to keep it without duplicating code and that was the main reason citing the info is available with -[gf]record-gcc-switches ... > --help=optimizers just documents optimization options, with no > indication which are enabled for a given compilation. Don't see how > this helps. ... and also by another means that I don't remember that shows the list of options but tells whether they are enabled or not. Seems like --help=optimizers indeed isn't it (or maybe it was it but it as well was imprecise and removed ...?). Ah! Use -Q --help=optimizers (how intuititve...)
