Subject: [patch 13/28] Add cmpxchg_local, cmpxchg64 and cmpxchg64_local to ia64
Date: Mon, 27 Aug 2007 11:52:47 -0400 [thread overview]
Message-ID: <20070827155527.817330797@polymtl.ca> (raw)
In-Reply-To: 20070827155234.062715780@polymtl.ca
[-- Attachment #1: add-cmpxchg-local-to-ia64.patch --]
[-- Type: text/plain, Size: 1567 bytes --]
Add the primitives cmpxchg_local, cmpxchg64 and cmpxchg64_local to ia64. They
use cmpxchg_acq as underlying macro, just like the already existing ia64
cmpxchg().
Changelog:
ia64 cmpxchg_local coding style fix
Quoting Keith Owens:
As a matter of coding style, I prefer
#define cmpxchg_local cmpxchg
#define cmpxchg64_local cmpxchg64
Which makes it absolutely clear that they are the same code. With your
patch, humans have to do a string compare of two defines to see if they
are the same.
