+Tell @value{GDBN} that readonly sections in your object file
+really are read-only (ie.@: that their contents will not change).
+In that case, @value{GDBN} can fetch values from these sections
+out of the object file, rather than from the target program.
+For some targets (notably embedded ones), this can be a significant
+enhancement to debugging performance.

+@item set trust-readonly-sections off
+Tell @value{gdbn} not to trust readonly sections.  This means that
+the contents of the section might change while the program is running,
+and must therefore be fetched from the target when needed.
