+# 
+#     PowerPC64 ELFv2 ABI 1/6: Code refactoring
+#     
+#     This is the first patch to support the new ELFv2 ABI in glibc.
+#     
+#     As preparation, this patch simply refactors some of the powerpc64 assembler
+#     code to move all code related to creating function descriptors (.opd section)
+#     or using function descriptors (function pointer call) into a central place
+#     in sysdep.h.
+#     
+#     Note that most locations creating .opd entries were already using macros
+#     in sysdep.h, this patch simply extends this to the remaining places.
+#     
+#     No relevant change in generated code expected.
+#
