--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
IMHO we at least shouldn't drop it in cases like:
int foo (int);
static inline int
bar (int x)
{
  [[gnu::musttail]] return foo (x + 1);
}
int
baz (int x)
{
  bar (x * 4); // The foo call from here shouldn't have musttail.
  [[gnu::musttail]] return bar (x * 2); // But from here it should have it
}
