set debug arch

Turns on or off display of gdbarch debugging info. The default is off

show debug arch

Displays the current state of displaying gdbarch debugging info.

set debug aix-thread

Display debugging messages about inner workings of the AIX thread module.

show debug aix-thread

Show the current state of AIX thread debugging info display.

set debug event

Turns on or off display of No value for GDBN event debugging info. The default is off.

show debug event

Displays the current state of displaying No value for GDBN event debugging info.

set debug expression

Turns on or off display of debugging info about No value for GDBN expression parsing. The default is off.

show debug expression

Displays the current state of displaying debugging info about No value for GDBN expression parsing.

set debug frame

Turns on or off display of No value for GDBN frame debugging info. The default is off.

show debug frame

Displays the current state of displaying No value for GDBN frame debugging info.

set debug infrun

Turns on or off display of No value for GDBN debugging info for running the inferior. The default is off. ‘infrun.c’ contains GDB's runtime state machine used for implementing operations such as single-stepping the inferior.

show debug infrun

set debug lin-lwp

Turns on or off debugging messages from the Linux LWP debug support.

show debug lin-lwp

set debug observer

Turns on or off display of No value for GDBN observer debugging. This includes info such as the notification of observable events.

show debug observer

Displays the current state of observer debugging.

set debug overload

Turns on or off display of No value for GDBN C++ overload debugging info. This includes info such as ranking of functions, etc. The default is off.

show debug overload

Displays the current state of displaying No value for GDBN C++ overload debugging info.

set debug remote

Turns on or off display of reports on all packets sent back and forth across the serial line to the remote machine. The info is printed on the No value for GDBN standard output stream. The default is off.

show debug remote

Displays the state of display of remote packets.

set debug serial

set debug target

Turns on or off display of No value for GDBN target debugging info. This info includes what is going on at the target level of GDB, as it happens. The default is 0. Set it to 1 to track events, and to 2 to also track the value of large memory transfers. Changes to this flag do not take effect until the next time you connect to a target or use the run command.

show debug target

Displays the current state of displaying No value for GDBN target debugging info.

set debugvarobj

Turns on or off display of No value for GDBN variable object debugging info. The default is off.
