One thing to be aware of is that your program is run via the shell
indicated by your @code{SHELL} environment variable if it exists; or
@code{/bin/sh} if not. This means that if you change any environment
variables in a @file{.cshrc} or @file{.bashrc} file, the changes will
affect your program. You may wish to move setting of environment
variables to @file{.login} or @file{.profile}.
@emph{Warning:} @value{GDBN} runs your program using the shell indicated
by your @code{SHELL} environment variable if it exists (or
@code{/bin/sh} if not). If your @code{SHELL} variable names a shell
that runs an initialization file---such as @file{.cshrc} for C-shell, or
@file{.bashrc} for BASH---any variables you set in that file will affect
your program. You may wish to move setting of environment variables to
files that are only run when you sign on, such as @file{.login} or
@file{.profile}.

@subsection @value{GDBN} and remote MIPS boards
@cindex MIPS boards
@value{GDBN} can use the MIPS remote debugging protocol to talk to a
MIPS board attached to a serial line. This is available when
you configure @value{GDBN} with @samp{--target=mips-idt-ecoff}.
@kindex target mips @var{port}
To run a program on the board, start up @code{@value{GDBP}} with the
name of your program as the argument. To connect to the board, use the
command @samp{target mips @var{port}}, where @var{port} is the name of
the serial port connected to the board. If the program has not already
been downloaded to the board, you may use the @code{load} command to
download it. You can then use all the usual @value{GDBN} commands.
@cindex @code{remotedebug}, MIPS protocol
@c FIXME! For this to be useful, you must know something about the MIPS
@c FIXME...protocol. Where is it described?
You can see some debugging information about communications with the board
by setting the @code{remotedebug} variable. If you set it to 1 using
@samp{set remotedebug 1} every packet will be displayed. If you set it
to 2 every character will be displayed. You can check the current value
at any time with the command @samp{show remotedebug}.
@kindex set mipsfpu off
@cindex MIPS remote floating point
@cindex floating point, MIPS remote
If your target board does not support the MIPS floating point
coprocessor, you should use the command @samp{set mipsfpu off} (you may
wish to put this in your @value{GDBINIT} file). This will tell
@value{GDBN} how to find the return value of functions which return
floating point values, and tell it to call functions on the board
without saving the floating point registers.
