<h1>Debug information</h1>
|
|
|
16 |
|
|
|
17 |
<p>The <b>Debug</b> perspective lets you manage the debugging or running of a program
|
|
|
18 |
in the Workbench. You can control the execution of your program by setting
|
|
|
19 |
breakpoints, suspending launched programs, stepping through your code, and
|
|
|
20 |
examining the contents of variables.</p>
|
|
|
21 |
<p> The <b>Debug</b> perspective displays the following information:</p>
|
|
|
22 |
|
|
|
23 |
<ul>
|
|
|
24 |
<li>The stack frame for the suspended threads
|
|
|
25 |
for each target that you are debugging</li>
|
|
|
26 |
<li>Each thread in your program represented as a node in the tree</li>
|
|
|
27 |
<li>The process for each program that you are running</li>
|
|
|
28 |
</ul>
|
|
|
29 |
<p>The <b>Debug</b> perspective also drives the <b>C/C++ Editor</b>. As you step
|
|
|
30 |
through your program, the <b>C/C++ Editor</b> highlights the location of the
|
|
|
31 |
execution pointer. </p>
|
|
|
32 |
|
|
|
33 |
<h2>Variables</h2>
|
|
|
34 |
|
|
|
35 |
<p>You can view information about the variables in a selected stack frame in the
|
|
|
36 |
Variables view. When execution stops, the changed values are
|
|
|
37 |
by default highlighted in red. Like the other debug-related views, the Variables view does
|
|
|
38 |
not refresh as you run your executable. A refresh occurs when execution stops.</p>
|
|
|
39 |
|
|
|
40 |
<h2>Expressions</h2>
|
|
|
41 |
|
|
|
42 |
<p>An expression is a snippet of code that can be evaluated to produce a result.
|
|
|
43 |
The context for an expression depends on the particular debug model. Some
|
|
|
44 |
expressions may need to be evaluated at a specific location in the program so
|
|
|
45 |
that the variables can be referenced. You can view information about expressions
|
|
|
46 |
in the Expressions view.</p>
|
|
|
47 |
|
|
|
48 |
<h2>Registers</h2>
|
|
|
49 |
|
|
|
50 |
<p>You can view information about the registers in a selected stack frame.
|
|
|
51 |
Values that have changed are highlighted in the Registers view when your program
|
|
|
52 |
stops.</p>
|
|
|
53 |
|
|
|
54 |
<h2>Memory</h2>
|
|
|
55 |
|
|
|
56 |
<p>You can inspect and change your process memory.</p>
|
|
|
57 |
|
|
|
58 |
<h2>Disassembly</h2>
|
|
|
59 |
|
|
|
60 |
<p>You can view disassembled code mixed with source information.</p>
|
|
|
61 |
|
|
|
62 |
<h2>Modules</h2>
|
|
|
63 |
|
|
|
64 |
<p>You can view information about the modules (executables and shared libraries) loaded
|
|
|
65 |
in the current debug session.</p>
|
|
|
66 |
|
|
|
67 |
<h2>Signals</h2>
|
|
|
68 |
|
|
|
69 |
<p>You can view the signals defined on the selected debug target and how the
|
|
|
70 |
debugger handles each one.</p>
