Software Config:
* Windows 10 2004 x64
* VS 2019 16.6.3 CMD Prompt
* Ninja 1.10.0 and 1.10.0git
* CMake 3.17.3 and 3.18.0-RC2
* Clang Git Release/10.x
* Perl: Strawberry Perl 5.30.2
* Python 3.8.2
* Happens with x86 and x64 Builds
* DISABLING Exception Handling and RTTI is not helping (no Idea if it
should / could)
* Trying to only build Project=Clang does not help either
* I am building Clang etc. in Release Mode without Issues since Clang
7.x Beta = Clang 10.0.1 Release works fine
* I only try to do a Debug Build since Clang 10, so I cant say if it
would have worked with older Versions
* I also only use Clang for the Qt QDoc Parser: I am not using Clang for
other things yet (mainly because building things still takes at least
1.5x longer with Clang and Ninja than VS and JOM). So I am still a
Beginner with Clang when it comes to everday usage

Ninja Command:

Is there any way to get more Infos like why llvm-tblgen.exe fails exactly?

Thanks!
