We have that, gcc -Q --help=warning
Of course, for warnings which do require arguments (numerical, or
enumeration/string), one still needs to pick up his choices of those
arguments; no idea what -Weverything would do here, while some warnings
have different levels where a higher (or lower) level is a superset of
another level, what numbers would you pick for e.g. warnings where the
argument is bytes?

For most of them, there is a value that maximizes the number of warnings,so the same superset argument applies. -Wframe-larger-than=0 so it showsthe estimated frame size on every function, -Walloca-larger-than=0 so itis equivalent to -Walloca, etc.
