Product: clang
Version: 9.0

windows cmd error output screenshot
I have downloaded and installed clang 9.0 on windows 10 from
http://releases.llvm.org/download.html and mingw 8.1 from
https://sourceforge.net/projects/mingw-w64/
I tried to compile sdl 2.0.10 with clang + mingw. I obtained an error relating
to intrin.h/xsaveintrin.h. Specifically:
function cannot return function type 'int (unsigned int)'
unsigned __int64 _xgetbv(unsigned int);
note: expanded from macro 'xgetbv'
#define _xgetbv(A) __builtin_ia32_xgetbv((long long)(A))
I was able to compile successfully with llvm 8.0, so I assume it is a problem
on the llvm end rather than sdl2.
Please view attachment for a detailed screenshot of windows cmd error output.
