Development Tools

Call Stack panel

This panel is used to display the call stack information for the function call (see "2.10.1 Display call stack information").

This panel appears only when connected to the debug tool.

Caution 1.

Nothing is displayed on this panel during execution of a program.
When the program is stopped, items in each area are displayed.

Caution 2.

Except for [Simulator]
If step execution is performed in source level, CS+ determines whether an interrupt is being processed via the NP, EP, and ID flags in the PSW register. For this reason, if the above register or flags are changed (e.g. when using multiple interrupts), then call stack information may be incorrect.

Remark

This panel can be zoomed in and out by in the tool bar, or by moving the mouse wheel forward or backward while holding down the [Ctrl] key.

Call Stack Panel

This section describes the following.

-	[How to open]

-	[Description of each area]

[Toolbar]

-	[[File] menu (Call Stack panel-dedicated items)]

-	[[Edit] menu (Call Stack panel-dedicated items)]

-	[Context menu]

[How to open]

-	From the [View] menu, select [Call Stack].

[Description of each area]

(1)	[Depth] area

The depth of the call is displayed.

The line at the current PC position becomes 0 and incremented numbers from 1 is added to the calling function in the order.

(2)	[Call Stack] area

The current source position and the call stack information pushed on the stack (position of the calling function and arguments of a each function, etc.) are displayed.

The display format in this area differs depending on the selection condition of the / button on the toolbar, or of [Show Parameter]/[Show Module File Name] from the context menu.

Condition

Display Format

-	Display arguments

-	Display module file name

<Function>(<Argument>=<Argument ValueNote>, ...)[<Module file name>$<File name>#<Line number>] (default)

-	Display arguments

-	Do not display module file name

<Function>(<Argument>=<Argument valueNote>, ...)[<File Name>#<Line number>]

-	Do not display arguments

-	Display module file name

<Function>()[<Module file name>$<File name>#<Line number>]

-	Do not display arguments

-	Do not display module file name

<Function>()[<File name>#<Line number>]

Note	When the argument value is character string, up to 20 characters can be displayed.

Remark

Array arguments are passed as pointers rather than arrays (C language specification). For this reason, if the argument is an array, it is displayed as a pointer.

This area is provided with the following functions.

(a)	Jump to the source line/disassemble line

By selecting [Jump to Source] from the context menu, the Editor panel is opened with moving the caret to the source line corresponding to the calling function at the current caret position (if the Editor panel is already open, the screen will jump to the panel).

In addition, similarly by selecting [Jump to Disassemble], the Disassemble panel (Disasemmble1) is opened with moving the caret to the address corresponding to the calling function at the current caret position (if the Disassemble panel is already open, the screen will jump to the panel (Disassemble1)).

Remark

It is possible to jump to the target source line by double-clicking on that line as well.

(b)	Display of local variables

By selecting [Jump to Local Variable at This Time] from the context menu, the Local Variables panel is opened to display the local variables indicated by the currently selected line.

(c)	Saving the contents of call stack information

By selecting the [File] menu >> [Save Call Stack Data As...], the Save As dialog box can be opened, and all the contents of this panel can be saved in a text file (*.txt) or CSV file (*.csv).

See "2.10.1.4 Save the contents of call stack information" for details on the method for saving the contents of call stack information.

[Toolbar]

The buttons below are disabled during execution of a program.

		Acquires the latest data from the debug tool, and updates the contents of this panel.
Notation		The following buttons to specify the notation of values are displayed.
	AutoSelect	Displays values on this panel in the default notation according to the type of variable (default).
	Hexadecimal	Displays values on this panel in hexadecimal number.
	Decimal	Displays values on this panel in decimal number.
	Octal	Displays values on this panel in octal number.
	Binary	Displays values on this panel in binary number.
Encoding		The following buttons to specify the encoding of character variables are displayed.
	ASCII	Displays character variables in ASCII code (default).
	Shift_JIS	Displays character variables in Shift_JIS code.
	EUC-JP	Displays character variables in EUC-JP code.
	UTF-8	Displays character variables in UTF-8 code.
	UTF-16	Displays character variables in UTF-16 code.
		Displays the call stack information with the module file name (default).
		Displays the call stack information with the parameters (arguments) of the function call (default).

[[File] menu (Call Stack panel-dedicated items)]

The following items are exclusive for the [File] menu in the Call Stack panel (other items are common to all the panels).

Note that all these items are disabled during execution of a program.

Save Call Stack Data

Overwrites the contents of this panel to the previously saved text file (*.txt)/CSV file (*.csv) (see "(c) Saving the contents of call stack information").

Note that when the file has never been saved or the file is write disabled, the same operation is applied as the selection in [Save Call Stack Data As...].

Save Call Stack Data As...

Opens the Save As dialog box to newly save the contents of this panel to the specified text file (*.txt)/CSV file (*.csv) (see "(c) Saving the contents of call stack information").

[[Edit] menu (Call Stack panel-dedicated items)]

The following items are exclusive for [Edit] menu in the Call Stack panel (all other items are disabled).

Copy	Copies the contents of the selected line to the clipboard.
Select All	Selects all the items of this panel.
Find...	Opens the Find and Replace dialog box with selecting the [Find in Files] tab.
Replace...	Opens the Find and Replace dialog box with selecting the [Replace in Files] tab.

[Context menu]

Copy		Copies the contents of the selected line to the clipboard.
Show Module File Name		Displays the call stack information with the module file name (default).
Show Parameter		Displays the call stack information with the parameters (arguments) of the function call (default).
Notation		The following cascade menus to specify the notation of values are displayed.
	AutoSelect	Displays values on this panel in the default notation according to the type of variable (default).
	Hexadecimal	Displays values on this panel in hexadecimal number.
	Decimal	Displays values on this panel in decimal number.
