> Why not just look for the AVX registers by name that are only available if they are correctly detected by the native lldb-server or debugserver? Then we can avoid all of this. If we don't execute any instructions that crash the program, we can stop before any specialized AVX instructions are executed and kill the program is we don't see a register by name?
I considered doing something like this, but I want to avoid relying on the AVX2 support in LLDB to work in order to detect AVX2. If I use an LLDB mechanism for this then (exaggerating here!) someone could remove AVX support from LLDB and this test would still pass.
