This looks indeed correct, although it is not yet in a released GCC
(testing quickly in Compiler Explorer, GCC 15.2 doesn't have it, but
GCC trunk has).
I will apply it -- Cc'ing ClangBuiltLinux and Kbuild so that they are aware.
Thanks!
Cheers,
Miguel

Yes, sorry I didn't mention that in my commit message; it's mentioned in
Kees' commit message (7454048db27d6).

Thank you!

Right, this does look correct, as this option is specific to GCC for the
purpose of exposing more information from GCC internals to the user for
understanding diagnostics better.
I will say if this makes 6.19, the stable tag is not necessary since
7454048db27d6 landed in 6.19-rc1 and I would not expect it to get
backported (but even if it did via AUTOSEL or something, the Fixes tag
should ensure it gets included).
Cheers,
Nathan
