$editline

1

$exitonterminationofprocesswithpid

None

If set to process ID (pid), when that process terminates, the debugger exits.

$float80bit

1

If set to 0 (the default), prints 128-bit floating point numbers normally;if set to a non-zero value, prints 128-bit floating point numbers as 128-bit containsers holding 80-bit floating point numbers.

$floatshrinking

1

If set to the default (1), the debugger prints binary floating point numbers using the shortest possible decimal number. If set to 0, the debugger prints the decimal number which is the closest representation in the number of decimal digits available of the internal binary number.

$framesearchlimit

0

Defines the maximum number of call frames by which to extend normal language-based identifier lookup.

$funcsig

1

Displays function signature at breakpoint.

$gdb_compatible_output

0

Makes IDB output compatible with GDB output.

$givedebughints

1

Displays hints on debugger features.

$hasmeta

0

Interprets multibyte characters.

$hexints

0

Displays integers in hex radix.

$highpc

(internal debugger variable)

Returns the highest address associated with "function".

$historylines

20

Defines the number of commands to show for history.

$indent

1

Prints structures with indentation.

$lang

"None"

Defines the programming language of current routine.

$lasteventmade

0

Displays the number of last (successful) breakpoint definition.

$lc_ctype

result of setlocale (LC_CTYPE,0L)

Defines the current locale information.

If set, passes the value through setlocale() and becomes the result.

"" is passed as 0L.

$listwindow

20

Displays the number of lines to show for list.

$main

"main"

Displays the name of the first routine in the program.

$maxstrlen

128

Defines the length of the largest string (in characters) to printed in full.

$memorymatchall

0

When set to non-zero, displays all memory matches in the specified range. Otherwise, only the first memory match is displayed.

$octints

0

Displays integers in octal radix.

$overloadmenu

1

Prompts for choice of overloaded C++ name.

$page

1

If non-zero, debugger terminal output is paged.

$pagewindow

0

Defines the number of lines per output page. The default of 0 causes the debugger to query the terminal for the page size.

$parallel_branchingfactor

8

Specifies the factor used to build the n-nary tree and determine the number of aggregators in the tree.

$parallel_aggregatordelay

3000 milliseconds

Specifies the length of time that aggregators wait before they aggregate and send messages down to the next level when not all the expected messages have been received.

$parentprocess

0

When the debugger detects a fork, it assigns the parent process ID to $parentprocess.

$pimode

0

Echoes input to log file on playback input. Only applicable to IDB mode.

$prettyprint

1

$prompt

"(idb)"

Specifies debugger prompt.

$readtextfile

0

If set to non-zero, instructions are read from the text area of the binary file rather than from the memory image.

$regstyle

1

Controls the format of register names during disassembly. Valid settings are:

0     compiler names, for example, t0, ra, or zero.

1     hardware names, for example, r1, r26, or r31.

2     assembly names, for example, $1, $26, or $31.

$repeatmode

1

Repeats previous command when you press Enter if 1.

$reportsotrans

0

Report when an event was changed because a shared object library was either opened or closed if 1.

$showlineonstartup

0

Displays the first executable line in main if 1.

$showwelcomemsg

1

Displays welcome message at startup time if 1.

$stackargs

0     Steps over routines.

1     Steps into routines.

$stoponattach

0

Stops the running process on attach if 1.

$symbolsearchlimit

100

Specifies the maximum number of symbols that will be returned by the whereis command for a regular expression search. The default value is 100; a value of 0 indicates no limit.

$threadlevel

The value native specifies native threads.

The debugger automatically sets $threadlevel to " openmp" when

• the debuggee is an OpenMP* program and
• the shared library libomp_db . so is set in LD_LIBRARY_PATH.

$usedynamictypes

1

Evaluates using C++ static (if 0) or dynamic (if 1) type.

$usesteppingrules

1

Controls filters for stepping into TBB and STD functions. Set the variable value to 1 to avoid stepping into TBB and STD functions based on namespaces.

$verbose

0

Produces even more output if 1.

$catchexecs

0

Stops execution on program exec.

$catchforkinfork

0

Notifies you as soon as the forked process is created (otherwise you are notified when the call finishes).

$catchforks

0
