test cases
Patch created:
https://github.com/9rnsr/dmd/compare/master...fix4424
Behaviors:
- if template opAssign exists, check it is identity opAssign.
- if template identity opAssign need, following opAsign build:
ref S opAsign(T:S)(T s) if (is(T == S))
{
T tmp = this; // bit copy
this = s; // bit copy
tmp.dtor();
return this;
}
- no changes with non tempate opAssign.
