Ups is a source level C debugger that runs under X11.
|
||
|
|
|
||
|
|
It runs in a window with two major regions: one showing the
|
||
|
|
current state of the target program data and the other showing
|
||
|
|
the currently executing source code. A key feature of ups is
|
||
|
|
that the variables display is persistent: when you add a variable
|
||
|
|
to the display it stays there as you step through the code. The
|
||
|
|
current stack trace (which function called which) is always visible.
|
||
|
|
|
||
|
|
Ups includes a C interpreter which allows you to add fragments
|
||
|
|
of code simply by editing them into the source window (the source
|
||
|
|
file itself is not modified). This lets you add debugging printf
|
||
|
|
calls without recompiling, relinking (or even restarting) the
|
||
|
|
target program. You can also add conditional breakpoints in a
|
||
|
|
natural way - you just add a statement like "if (i == 73) #stop"
|
||
|
|
at the appropriate place in the source window.
