How do you set breakpoints in gdb?

You can also set breakpoints on function names. To do this, just type “break [functionname]”. gdb will stop your program just before that function is called. Breakpoints stay set when your program ends, so you do not have to reset them unless you quit gdb and restart it.

What is gdb please explain?

GDB stands for GNU Project Debugger and is a powerful debugging tool for C(along with other languages like C++). It helps you to poke around inside your C programs while they are executing and also allows you to see what exactly happens when your program crashes. To exit out of gdb, type quit or q.

How to set hardware assisted breakpoint in gdb?

What happens if the breakpoint cond is invalid in gdb?

The breakpoint may be mapped to multiple locations. If the breakpoint condition cond is invalid at some but not all of the locations, the locations for which the condition is invalid are disabled. For example, GDB reports below that two of the three locations are disabled.

Is the breakpoint the same as the hbreak command?

The args are the same as for the hbreak command and the breakpoint is set in the same way. However, like the tbreak command, the breakpoint is automatically deleted after the first time your program stops there. Also, like the hbreak command, the breakpoint requires hardware support and some target hardware may not have this support.

When does a function name refer to a breakpoint?

The breakpoint will stop your program just before it executes any of the code in the specified location . When using source languages that permit overloading of symbols, such as C ++, a function name may refer to more than one possible place to break. See Ambiguous Expressions, for a discussion of that situation.
