--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The following is a valid use of extern inline I think
extern int memcmp (const void * p, const void *q, unsigned long size);
extern inline __attribute__((always_inline,gnu_inline))
int memcmp (const void * p, const void *q, unsigned long size)
{
return memcmp (p, q, size);
}
int foo (const void * p, const void *q)
{
return memcmp (p, q, 4);
}
I think the user needs to avoid name-lookup issues here by using an alias
for the call to memcmp in the inline wrapper which might also avoid the
diagnostic. That __builtin_memcmp finds the memcmp definition is quite
unfortunate and makes it not usable as a way to avoid using an alias.
