GDB: Switch to thread when breakpoint is hit

I set a breakpoint in a multi-threaded inferior. Any of the threads could hit the breakpoint. When the breakpoint is hit, I would like to have gdb switch to the thread that hit it.



Currently, I'm notified that bp is hit. Then I have to look at the top stack frame of every thread to know which one it was, like so:



(gdb) info threads

(gdb) thread apply all bt 1 full

(gdb) thread 2


I'd like this switching to be automatic.

          GDB should already do this automatically, see documentation:




          Whenever GDB stops your program, due to a breakpoint or a signal, it
          automatically selects the thread where that breakpoint or signal
          happened. GDB alerts you to the context switch with a message such as
          ‘[Switching to Thread n]’ to identify the thread.




          Apart from notifying that the breakpoint was hit you should also be notified about switching to another thread.

                    Image
                    Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
