# $NetBSD: Makefile,v 1.11 2016/06/12 14:33:57 wiz Exp $
Import libatomic_ops-20081024 (version 1.2) The latest code is only found in the boehm-gc CVS repository (see Makefile.version for information). I had to take this from there, as there were bug fixes. This library was imported primarily for the [hopefully] upcoming audio/pulseaudio package. TODO: Add support for NetBSD atomic ops? 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. As the latest code for this library is only available via CVS, this package provides a snapshot.

Import libatomic_ops-20081024 (version 1.2) The latest code is only found in the boehm-gc CVS repository (see Makefile.version for information). I had to take this from there, as there were bug fixes. This library was imported primarily for the [hopefully] upcoming audio/pulseaudio package. TODO: Add support for NetBSD atomic ops? 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. As the latest code for this library is only available via CVS, this package provides a snapshot.
