--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The C++ front-end does:
/* Handle gnu_inline attribute. */
if (GNU_INLINE_P (decl1))
{
DECL_EXTERNAL (decl1) = 1;
DECL_NOT_REALLY_EXTERN (decl1) = 0;
DECL_INTERFACE_KNOWN (decl1) = 1;
DECL_DISREGARD_INLINE_LIMITS (decl1) = 1;
}
C front-end does:
/* For GNU C extern inline functions disregard inline limits. */
if (DECL_EXTERNAL (fndecl)
&& DECL_DECLARED_INLINE_P (fndecl)
&& (flag_gnu89_inline
|| lookup_attribute ("gnu_inline", DECL_ATTRIBUTES (fndecl))))
DECL_DISREGARD_INLINE_LIMITS (fndecl) = 1;
This specifically from r0-82849-gc536a6a77a19a8 but it was done different
before that (using a language hook).

It looks like it has been this way since r0-37737-g4838c5ee553f06 (2001) (or
rather that is when it was used by the tree inline; I don't want to dig further
back to understand the RTL inliner). So looks like this is just missing
documentation ...
