   the ability to set breakpoints on inlined functions will be lost

+  The .gdb_index section has also been updated to record more information
+  about each symbol.  This speeds up the "info variables", "info functions"
+  and "info types" commands when used with programs having the .gdb_index

 * Ada support for GDB/MI Variable Objects has been added.

 * GDB can now support 'breakpoint always-inserted mode' in 'record'
