[PATCH] D41962: Fix TestYMMRegisters for older machines without AVX2

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: packages/Python/lldbsuite/test/functionalities/register/intel_avx/main.c:21
+  static volatile unsigned haveAVX2;
+  haveAVX2 = __builtin_cpu_supports("avx2");
   unsigned int ymmallones = 0xFFFFFFFF;
----------------
Note that you need to call `__builtin_cpu_init()` before calling `__builtin_cpu_supports()`.
Or maybe it is already called before this?
