While the AMD Linux graphics team is busy proposing an LLVM back-end staging area
, the AMD CPU folks have begun work on the GCC compiler and preparing support for the next-generation Bobcat processors.
Venkataramanan Kumar of AMD India has published "btver2" patches for the GNU Compiler Collection to target the next-generation Bobcat hardware that makes up AMD's Fusion APU brand.
The new AMD btver2 enablement support for GCC doesn't provide anything too revealing at this time, but hopefully new details will be shed as the Bobcat 2 compiler support matures.
The AMD btver2 patch-work for GCC begins here
on the mailing list. This is work for possible inclusion into GCC 4.8
