Hi @bob.wilson – Am I missing something here?

@bob.wilson – Ping. While Ivy Bridge (or really, Sandy Bridge) has AVX1, which enables faster memcpy, memset, and even memcmp (for common scenarios). If there is something I'm missing? If you can't explain why, that's okay. :-)

@bob.wilson no longer works on llvm-project. I added Gerolf and Duncan.

Okay. I'm going to abandon this patch on the assumption that Apple has an internal bug tracking this.
