hans added a comment.
Apologies for the slow reply, it was a long weekend here.

Comment at: clang/lib/Parse/ParseDeclCXX.cpp:3314
if (getLangOpts().CPlusPlus && Tok.is(tok::identifier)) {
- VirtSpecifiers::Specifier Specifier = isCXX11VirtSpecifier(Tok);
- assert((Specifier == VirtSpecifiers::VS_Final ||
- Specifier == VirtSpecifiers::VS_GNU_Final ||
- Specifier == VirtSpecifiers::VS_Sealed) &&
+ for (VirtSpecifiers::Specifier Specifier = isCXX11VirtSpecifier(Tok);
+ Specifier != VirtSpecifiers::VS_None;

I still think the for-loop is confusing. How about something like this, then?
```
while (true) {
VirtSpecifiers::Specifier Specifier = isCXX11VirtSpecifier(Tok);
if (Specifier == VirtSpecifiers::VS_None)
break;
...
}
```
I agree that renaming isCXX11VirtSpecifier in a separate patch is a good idea.

+ case VS_Abstract:
+ VS_abstractLoc = Loc;
+ break;

Yes, ignoring it is fine. (Re-formatting the whole switch would also be okay,
as long as its consistent.)
================
Comment at: clang/lib/Sema/DeclSpec.cpp:1493
case VS_Sealed: return "sealed";
+ case VS_Abstract:
+ return "abstract";

Ignoring clang-format is fine, sticking to the current style is usually
preferred..
