|
||||||
|
Provides implementations for atomic memory update
|
||||||
|
operations on a number of architectures. This allows
|
||||||
|
direct use of these in reasonably portable code. Unlike
|
||||||
|
earlier similar packages, this one explicitly considers
|
||||||
|
memory barrier semantics, and allows the construction of
|
||||||
|
code that involves minimum overhead across a variety of
|
||||||
|
architectures.

Version: 1.0-3

|
Tags: patch
|
||||||
|
|
||||||
|
Libatomic-ops currently FTBFS on mips/mipsel because there is no
|
||||||
|
arch-specific implementation, and the generic pthread isn't configured.
|
||||||
|
|
||||||
|
The appended patch adds a basic implementation for linux.
