c++: defaulted comparisons and vptr fields [PR95567]
We need to explicitly skip over vptr fields when synthesizing a
defaulted comparison operator, because next_initializable_field
doesn't do so for us.
PR c++/95567
gcc/cp/ChangeLog:
* method.c (build_comparison_op): Skip DECL_VIRTUAL_P fields.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/spaceship-virtual1.C: New test.
