The memalign man page on Solaris and QNX lists an additional requirement
for the alignment value that is not present in all implementation of
that non-standard function. For both those targets we should actually be
using posix_memalign anyway, so it doesn't matter. This just adds a
comment making note of that fact.
libstdc++-v3/ChangeLog:
* libsupc++/new_opa.cc (aligned_alloc): Add comment.
static inline void*
aligned_alloc (std::size_t al, std::size_t sz)
{
+ // Solaris requires al >= sizeof a word and QNX requires >= sizeof(void*)
+ // but they both provide posix_memalign, so will use the definition above.
return memalign (al, sz);
}
#else // !HAVE__ALIGNED_MALLOC && !HAVE_POSIX_MEMALIGN && !HAVE_MEMALIGN
