Subject: [Buildroot] [PATCH v4] arch: add support for "jaguar" AMD CPU optimisations.
Date: Wed, 15 Jan 2014 11:20:08 -0500 (EST)	[thread overview]
Message-ID: <403077357.139986.1389802808673.JavaMail.root@mail> (raw)
In-Reply-To: <828938079.582663.1389643754921.JavaMail.root@mail>

AMD Jaguar ( https://en.wikipedia.org/wiki/Jaguar_%28microarchitecture%29 ) is suddenly
a popular architecture since it is used in the PS4 and the XBox One.
Many embedded systems are also likely to use it in the next years.

This patch adds support for GCC architecture-specific optimizations and tuning for these CPUs.
These optimizations are available with GCC 4.8+.
