d: Warn when declared size of a special enum does not match its intrinsic type.
All special enums have declarations in the D runtime library, but the
compiler will recognize and treat them specially if declared in any
module. When the underlying base type of a special enum is a different
size to its matched intrinsic, then this can cause undefined behavior at
runtime. Detect and warn about when such a mismatch occurs.
gcc/d/ChangeLog:
* gdc.texi (Warnings): Document -Wextra and -Wmismatched-special-enum.
* implement-d.texi (Special Enums): Add reference to warning option
-Wmismatched-special-enum.
* lang.opt: Add -Wextra and -Wmismatched-special-enum.
* types.cc (TypeVisitor::visit (TypeEnum *)): Warn when declared
special enum size mismatches its intrinsic type.
gcc/testsuite/ChangeLog:
* gdc.dg/Wmismatched_enum.d: New test.
