gdb - how to trace functions during execution. Ask Question Asked 3 years, 9 months ago. Active 3 years, 9 months ago. Viewed 387 times 0 I am trying hard how in gdb we can trace functions call but not able to achieve so - is there a way in GDB that when I run the executable I can print/trace functions name currently executing? ...
GDBTrace: A Tool for Tracing Program Execution at …
https://www.site.uottawa.ca/~tcl/papers/Cascon/GdbTrace.pdf
GDBTrace implements the -b, -B, -c and - C commands, which are used to control the start and end of the tracing process. The -b command is used to indicate to GDBTrace to start tracing indefinitely from this point. It has the lowest priority of the start/end tracing commands, in the sense that the other commands can force tracing to stop.
Dynamic Tracing with GDB - Heinrich Hartmann

gdb -ex 'target sim' -ex 'load' -ex 'run' a.out. -batch. Run in batch mode. Exit with status 0 after processing all the command files specified with ‘-x’ (and all commands from initialization files, if not inhibited with ‘-n’). -p number. Connect to process ID number, as with the attach command.
Process Record and Replay (Debugging with GDB)
https://sourceware.org/gdb/onlinedocs/gdb/Process-Record-and-Replay.html
In this format, the processor stores the execution trace in a compressed form that is afterwards decoded by GDB. The trace can be recorded with very low overhead. The compressed trace format also allows small trace buffers to already contain a big number of instructions compared to BTS. Decoding the recorded execution trace, on the other hand, is more expensive than …
How to get a full execution trace with Python gdb?

import gdb gdb.execute('break main') gdb.execute('run') while (True): gdb.write (gdb.execute('x /i $pc', to_string=True).rstrip('\n'), gdb.STDOUT) gdb.execute('stepi', to_string=False) gdb.flush () Then, just execute: $> gdb -x ./script.py ./main 1> log.txt The problems that I …
GDB Introspect Trace Debugging: Commands

GDB Tracing Commands Tracing program execution: the record/playback model Some program behaviors can be analyzed only by collecting data over long periods of time for later analysis. Other problems occur in sections of code that are too time-sensative to be debugged interactively.

Trace Function Calls Using GDB - A Random Walk Down Tech Street Trace Function Calls Using GDB Sometimes it is easier to debug when you are able to view a call trace of all function calls in a particular program. This is especially true when working with code that isn’t yours or when debugging issues such as infinite loops in your own code.

1 Answer Sorted by: 0 GDB can't do that automatically, but with simple script you should be able to step a program, until it ends and log everything. This will execute very slowly, as CPU will handle a breakpoint every few instructions. …
GDB (Step by Step Introduction) - GeeksforGeeks
https://www.geeksforgeeks.org/gdb-step-by-step-introduction/
Here are few useful commands to get started with gdb for the above example:- run or r –> executes the program from start to end. break or b –> sets breakpoint on a particular line. disable -> disable a breakpoint. enable –> enable a disabled breakpoint. next or n -> executes next line of code, but don’t dive into functions.
Debugging with GDB - Altering Execution
https://web.mit.edu/gnu/doc/html/gdb_13.html
By default, GDB opens the file containing your program's executable code (or the corefile) read-only. This prevents accidental alterations to machine code; but it also prevents you from intentionally patching your program's binary. If you'd like to be able to patch the binary, you can specify that explicitly with the set write command.
