I don't think that may_alias is an attribute that needs to be mangled, as its
semantics affect code generation but not interfacing. For example:
void foo(int *x __attribute__((may_alias));
and
void foo(int *x);
are not distinguishable at the point of the caller -- but only affect code
generation in foo() itself.
But only one direction of conversion makes sense implicitly: the usual
contra-variance applies. And, S<int *> and S<int *x
__attribute__((may_alias))> are different types, and therefore must be
mangled differently; you certainly can't assume silent conversion
between them.
