vec_vslv and vec_vsrv are confusing in their own right and even more so because they operate only with big-endian semantics. Some examples are warranted. Note that the respective examples are arranged such that the impact of shifting in zero bits has a visible impact. Signed-off-by: Paul A. Clarke <firstname.lastname@example.org>

Programming Guides for Linux on Power
This project contains documentation helpful to application developers for Linux on OpenPOWER systems. The following documents are contained:
Linux on Power Porting Guide: Vector Intrinsics -- A guide to porting x86 vector intrinsics to the OpenPOWER processor. The online version of the document can be found in the OpenPOWER Foundation Document library at TBD.
Intrinsic Function Programming Reference -- A document detailing the various vector intrinsics on the OpenPOWER processor. This document is just beginning to be created.
To build this project, one must ensure that the Docs-Master project has also been cloned at the same directory level as the Programming-Guides project. This can be accomplished with the following steps:
- Clone the master documentation project (Docs-Master) using the following command:
$ git clone https://github.com/OpenPOWERFoundation/Docs-Master.git
- Clone this project (Programming-Guides) using the following command:
$ git clone https://github.com/OpenPOWERFoundation/Programming-Guides.git
- Build all the documents withing the project with these commands:
$ cd Programming-Guides $ mvn clean generate-sources
The project which controls the look and feel of the document is the Docs-Maven-Plugin project, an OpenPOWER Foundation private project on GitHub. To obtain access to the Maven Plugin project, contact Jeff Scheel (email@example.com) or Jeff Brown (firstname.lastname@example.org).
