%description -n %{libname_devel}
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.
The package has been at least minimally tested on X86, Itanium, Alpha,
PA-RISC, PowerPC, and SPARC, with Linux, Microsoft Windows, HP/UX, Solaris
and MACOSX operating systems. Some implementations are more complete than
others.
It should be useful both for high performance multi-threaded code which can't
afford to use the standard locking primitives, or for code that has to access
shared data structures from signal handlers. For details, see README.txt in
the distribution.
The most recent version adds support for operations on data of different
sizes, and adds an optional library providing almost-lock-free stacks (see
Boehm, "An almost non-blocking stack", also here) and a signal-handler-safe
memory allocator based on it. See README_stack.txt and README_malloc.txt for
details.

%description devel-static
This package provides semi-portable access to hardware provided
atomic memory operations. These might allow you to write code:
- That does more interesting things in signal handlers.
- Makes more effective use of multiprocessors by allowing you to write
clever lock-free code. Note that such code is very difficult to get
right, and will unavoidably be less portable than lock-based code. It
ia also not always faster than lock-based code. But it may occasionally
be a large performance win.
- To experiment with new and much better thread programming paradigms, etc.
It should be useful both for high performance multi-threaded code which can't
afford to use the standard locking primitives, or for code that has to access
shared data structures from signal handlers. For details, see README.txt in
