--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
tolower is defined in the header file as:
extern __inline __attribute__ ((__gnu_inline__)) int
__attribute__ ((__nothrow__ , __leaf__)) tolower (int __c)
{
  return __c >=3D -128 && __c < 256 ? (*__ctype_tolower_loc ())[__c] : __c;
}


So __builtin_tolower is not using that inline function. So this is a front-=
end
issue where the the two function decls are not being merged into one or is =
an
inliner issue.=
