ahatanak added a comment.
I had a discussion with Duncan today and he pointed out that perhaps we
shouldn't allow users to annotate a struct with "trivial_abi" if one of its
subobjects is non-trivial and is not annotated with "trivial_abi" since that
gives users too much power.
Should we error out or drop "trivial_abi" from struct Outer when the following
code is compiled?
struct Inner1 {
~Inner1(); // non-trivial
int x;
};
struct __attribute__((trivial_abi)) Outer {
~Outer();
Inner1 x;
};
The current patch doesn't error out or drop the attribute, but the patch would
probably be much simpler if we didn't allow it.
