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.
