[gst-devel] Orc-0.4.5 Release

[David Schleef]

ORC - The Oil Runtime Compiler
==============================

(and OIL stands for Optimized Inner Loops)

Entropy Wave Inc (http://entropywave.com/) presents Orc, the sucessor
to Liboil - The Library of Optimized Inner Loops.

Orc is a library and set of tools for compiling and executing
very simple programs that operate on arrays of data.  The "language"
is a generic assembly language that represents many of the features
available in SIMD architectures, including saturated addition and
subtraction, and many arithmetic operations.

At this point, developers interested in using Orc should look at the
examples and try out a few Orc programs in an experimental branch
of their own projects.  And provide feedback on how it works.  There
will likely be some major changes in ease of use from a developer's
perspective over the next few releases.

The 0.4 series of Orc releases will be API and ABI compatible, and
will be incompatible with the 0.5 series when it comes out.  The first
release of the 0.5 series is anticipated to coincide with the release
of GStreamer 1.0.


Changes in 0.4.5
================

This release contains many small improvements related to
converting GStreamer from liboil to Orc.

The major addition in this release is the mainstreaming of
the NEON backend, made possible by Nokia.

There is a new experimental option to ./configure,
--enable-backend, which allows you to choose a single code
generation backend to include in the library.  This is mostly
useful for embedded systems, and is not recommended in general.

The upcoming release will focus on improving code generation
for the SSE and NEON backends.
