Subject: [PATCH][clang] AMD k8 family does not support SSE4.x which are
|
|
required by x86-64-v2+
|
|
|
|
So don't define __tune__k8__ for these micro architecture.
|
|
|
|
SSE, SSE2 and SSE3 appear in https://www.amd.com/system/files/TechDocs/25112.PDF
|
|
but not SSE4.x.
|
|
|

|
|
(cherry picked from commit 092c303955cd18be6c0b923b1c0a1b96e2c91893)
