 * The .gdb_index section has been updated to include symbols for
   inlined functions.  GDB will ignore older .gdb_index sections by
   default, which could cause symbol files to be loaded more slowly

-  --use-deprecated-index-sections will cause GDB to use any older

+  and "info types" commands when used with programs having the .gdb_index
