I get:
sincostmp.5 = __builtin_cexpi (phi);
REALPART_EXPR <> = REALPART_EXPR ;
IMAGPART_EXPR <> = IMAGPART_EXPR ;
return ;
Which is created after the sincos pass as:
sincostmp.5_7 = __builtin_cexpi (phi_1(

typo, I meant "libcall" not "sibcall"

you are right, it's not a sibcall, my mistake.
But even at the tree level I still don't see the builtin marked as tailcall. On
a reduced case when entering find_tail_calls I have
D.1177_2 = __builtin_cos (phi_1(D));

Which is unlike the other case where we don't have a call at the tree level
that gets marked as tail called.

It is not since this is not a libcall. At the tree level, we have a __builtin
function which has been marked for tailcall.

I think this is a duplicate of #15473 (Sibcall optimization for libcalls).
