C++ test case
The attached test case puts mask registers in inline assembly where the code
specifies a general purpose register. Assembly fails. This bug is observed in
Clang version 6.0.0 Ubuntu under WSL. The bug does not occur with Cygwin Clang
5.0.1.
Compile the attached test case with:
clang -m64 -O2 -mavx512bw -mavx512dq -mavx512vl test.cpp -c</pre>
