These commands are available @emph{only} when @value{GDBN} is configured
for debugging programs on Alpha or MIPS processors.
+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}.
