[Bug middle-end/83487] [8 Regression] ICE in expand_call, at calls.c:4098


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83487

--- Comment #18 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I thought I've done it here by CCing relevant people.  Or who else stands
behind the x86-64 psABI these days?

Anyway, I was looking at 0.95, seems newer psABI has more rules in there. 
Perhaps we can say that aggregates that recursively contain no fields except
other aggregates/unions/arrays have NO_CLASS class regardless of the size, then
there just would need to be an exception for the > 16 byte <= 64 byte
aggregates with all NO_CLASS classes, those shouldn't be passed in memory.
