@subsection Atmel AVR
@cindex AVR
When configured for debugging the Atmel AVR, @value{GDBN} supports the
following AVR-specific commands:
@table @code
@item info io_registers
@kindex info io_registers@r{, AVR}
@cindex I/O registers (Atmel AVR)
This command displays information about the AVR I/O registers. For

@cindex CRIS version
Set the current CRIS version to @var{ver}. The CRIS version affects
register names and sizes. This command is useful in case
autodetection of the CRIS version fails.
@item show cris-version
Show the current CRIS version.
@item set cris-dwarf2-cfi
@cindex DWARF-2 CFI and CRIS
Set the usage of DWARF-2 CFI for CRIS debugging. The default is off

on.
@item show cris-dwarf2-cfi
Show the current state of using DWARF-2 CFI.

Several MIPS-specific commands are available when debugging MIPS
programs:
@table @code
@item set mips saved-gpreg-size @var{size}
@kindex set mips saved-gpreg-size
@cindex MIPS GP register size on stack
Set the size of MIPS general-purpose registers saved on the stack.
The argument @var{size} can be one of the following:
@table @samp
@item 32
32-bit GP registers
@item 64
64-bit GP registers
@item auto
Use the target's default setting or autodetect the saved size from the
information contained in the executable. This is the default
@end table
@item show mips saved-gpreg-size
@kindex show mips saved-gpreg-size
Show the current size of MIPS GP registers on the stack.
@item set mips stack-arg-size @var{size}
@kindex set mips stack-arg-size
@cindex MIPS stack space for arguments
Set the amount of stack space reserved for arguments to functions.
The argument can be one of @code{"32"}, @code{"64"} or @code{"auto"}
(the default).
@item set mips abi @var{arg}
@kindex set mips abi
@cindex set ABI for MIPS
Tell @value{GDBN} which MIPS ABI is used by the inferior. Possible
values of @var{arg} are:
@table @samp
@item auto
The default ABI associated with the current binary (this is the
default).
@item o32
@item o64
@item n32
@item n64
@item eabi32
@item eabi64
@item auto
@end table
@item show mips abi
@kindex show mips abi
Show the MIPS ABI used by @value{GDBN} to debug the inferior.
@item set mipsfpu
@itemx show mipsfpu
@xref{MIPS Embedded, set mipsfpu}.
@item set mips mask-address @var{arg}
@kindex set mips mask-address
@cindex MIPS addresses, masking
This command determines whether the most-significant 32 bits of 64-bit
MIPS addresses are masked off. The argument @var{arg} can be
@samp{on}, @samp{off}, or @samp{auto}. The latter is the default
setting, which lets @value{GDBN} determine the correct value.
@item show mips mask-address
@kindex show mips mask-address
Show whether the upper 32 bits of MIPS addresses are masked off or
not.
@item set remote-mips64-transfers-32bit-regs
@kindex set remote-mips64-transfers-32bit-regs
This command controls compatibility with 64-bit MIPS targets that
transfer data in 32-bit quantities. If you have an old MIPS 64 target
that transfers 32 bits for some registers, like @sc{sr} and @sc{fsr},
and 64 bits for other registers, set this option to @samp{on}.
@item show remote-mips64-transfers-32bit-regs
@kindex show remote-mips64-transfers-32bit-regs
Show the current setting of compatibility with older MIPS 64 targets.
@item set debug mips
@kindex set debug mips
This command turns on and off debugging messages for the MIPS-specific
target code in @value{GDBN}.
@item show debug mips
@kindex show debug mips
Show the current setting of MIPS debugging messages.
@end table
@node HPPA
@subsection HPPA
@cindex HPPA support
When @value{GDBN} is debugging te HP PA architecture, it provides the
following special commands:
@table @code
@item set debug hppa
@kindex set debug hppa
THis command determines whether HPPA architecture specific debugging
messages are to be displayed.
@item show debug hppa
Show whether HPPA debugging messages are displayed.
@item maint print unwind @var{address}
@kindex maint print unwind@r{, HPPA}
This command displays the contents of the unwind table entry at the
given @var{address}.
