Subject: [PATCH 02/21] X86_64, UV: Add UV Architecture Defines
Date: Thu, 28 Apr 2016 18:10:33 -0500 [thread overview]
Message-ID: <20160428231031.727194291@asylum.americas.sgi.com> (raw)
In-Reply-To: 20160428231031.265120287@asylum.americas.sgi.com
[-- Attachment #1: uv4_add_is_uvX_conditionals --]
[-- Type: text/plain, Size: 2197 bytes --]
Add defines to control which UV architectures are supported, and modify the
'if (is_uvX_*)' functions to return constant 0 for those not supported.
This will help optimize code paths when support for specific UV arches
is removed.
