These commands are available @emph{only} when @value{GDBN} is configured

Several MIPS-specific commands are available when debugging MIPS

@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

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

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 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

following special commands:
|

@table @code

messages are to be displayed.
|

@item show debug hppa
|

Show whether HPPA debugging messages are displayed.
|
