+* New command "set trust-readonly-sections on[off]".
+
+This command is a hint that tells gdb that read-only sections
+really are read-only (ie. that their contents will not change).
+In this mode, gdb will go to the object file rather than the
+target to read memory from read-only sections (such as ".text").
+This can be a significant performance improvement on some
+(notably embedded) targets.
 
 * New command "generate-core-file" (or "gcore").
 
-This new gdb command allows the user to drop a core file of the
-child process state at any time.  So far it's been implemented 
-only for Linux and Solaris, but should be relatively easily 
-ported to other hosts.  Argument is core file name (defaults 
-to core.<pid>).
