+
+ Fix ABI compatibility with libc compiled with old tools on powerpc.
+ Changes contributed by Franz Sirl <Franz.Sirl-kernel@lauterbach.com>
+ and Jack Howarth <howarth@bromo.med.uc.edu>.
+ * sysdeps/powerpc/Makefile [$(have-protected) = yes]
+ (CPPFLAGS-divdi3.c, CPPFLAGS-libgcc-compat.S): New variables,
+ pass -DHAVE_DOT_HIDDEN for these files.
+ * sysdeps/powerpc/Versions (libc: GLIBC_2.0): Added __floatdidf,
+ __floatdisf.
+ * sysdeps/powerpc/divdi3.c: New file.
+ * sysdeps/powerpc/libgcc-compat.S: New file, replacement for ...
+ * sysdeps/powerpc/libgcc-compat.c: ... this, file removed.
+
