--- Comment #10 from Martin Liška <marxin at gcc dot gnu.org> --- > But the sphinx generated index is not very useful as it lists all options > under symbols heading which is very confusing to programmers. It's a minor limitation, one can still jump to individual listings of options: https://gcc.gnu.org/onlinedocs/gcc/gcc-command-options.html Plus, there's a built-in search capability that can point you to an option if you know the name.
