Re: Ada and SIMD

[anon@anon.org (anon)]

Adacore created the Altivec packages set back in 2005 for GNAT PRO and 
now you can find some of these packages in GNU GNAT 4.2.0 and 4.3.0 
and future.  

Note: These packages are designed for PowerPC processor.

 g-allein.ads  GNAT.Altivec.Low_Level_Interface

 g-alleve.adb  GNAT.Altivec.Low_Level_Vectors
