This section describes characteristics of architectures that affect
all uses of gdb with the architecture, both native and cross.
20.4.3. MIPS
Alpha- and MIPS-based computers use an unusual stack frame, which
sometimes requires gdb to search backward in the object code to
find the beginning of a function.
To improve response time (especially for embedded applications, where
gdb 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:
- set heuristic-fence-post limit
Restrict gdb to examining at most limit bytes in its
search for the beginning of a function. A value of 0 (the
default) means there is no limit. However, except for 0, the
larger the limit the more bytes heuristic-fence-post must search
and therefore the longer it takes to run.
- show heuristic-fence-post
Display the current limit.
These commands are available only when gdb is configured
for debugging programs on Alpha or MIPS processors.
