+@cindex MIPS stack
+MIPS based computers use an unusual stack frame, which sometimes

+@cindex response time, MIPS debugging
+To improve response time (especially for embedded applications, where
+@value{GDBN} may be restricted to a slow serial line for this search)
+you may want to limit the size of this search, using one of these
+commands:
+@c FIXME! So what happens when GDB does *not* find the beginning of a
+@c function?

+Restrict @var{GDBN} to examining at most @var{limit} bytes in its search
+for the beginning of a function.  A value of @code{0} (the default)
