+Title: new CPU_FLAGS_PPC USE_EXPAND
+Author: Georgy Yakovlev <gyakovlev@gentoo.org>

+
+A new set of CPU_FLAGS_PPC USE_EXPAND flags has been added.
+The flags are:
+
+  altivec - Use the AltiVec/VMX instruction set
+  vsx - Use the Vector Scalar Extension instruction set
+  vsx3 - Use the Vector Scalar Extension v.3 instruction set
+
+Note that CPU_FLAGS_PPC variable is used on ppc and ppc64 architectures.
+
+In order to transition to new set of flags, if the following flag was
+was present:
+ 
+  USE="altivec"
+
+This flag needs to be set as:
+
+  CPU_FLAGS_PPC="altivec"
+
+It's advised to keep 'altivec' USE flag enabled to ensure safe
+migration and compatibility with external repositories.
+'vsx' and 'vsx3' are new flags and no migration necessary.
+
+To help users enable the correct USE_EXPAND flags PPC support has been
+added to app-portage/cpuid2cpuflags package:
+
+  # emerge -1v >=app-portage/cpuid2cpuflags-7
+  $ cpuid2cpuflags
