From 35a764036ae511f9269e3ed6da91e1db613272be Mon Sep 17 00:00:00 2001 From: William Lee Irwin III Date: Tue, 19 Oct 2004 18:14:28 -0700 Subject: [PATCH] [PATCH] sparc32: add atomic_sub_and_test() Add atomic_sub_and_test() to sparc32, implemented in terms of atomic_sub_return(), so reiser4 can be simultaneously microoptimized for x86 and made to pass compilation testing on sparc32.
