c - 如何跳过 GDB 中循环的多次迭代？

Question

假设我有一个将迭代 100 次的循环，我想跳过 50 次迭代，但我想从那里继续按 next 以查看每一行。

我不想在循环后设置断点，因为这样我会跳过所有迭代，而不仅仅是我想要的次数。

有没有办法在 GDB 中做到这一点？怎么办？

附言我不想从头到尾一直按 next。这很耗时...

Answer 1

在循环中设置断点，然后调用c 50继续50次

Debugging with GDB

5.2 Continuing and stepping

continue [ignore-count]
c [ignore-count]
fg [ignore-count]
Resume program execution, at the address where your program last stopped; any breakpoints set at that address are bypassed. The optional argument ignore-count allows you to specify a further number of times to ignore a breakpoint at this location; its effect is like that of ignore (see section Break conditions). The argument ignore-count is meaningful only when your program stopped due to a breakpoint. At other times, the argument to continue is ignored.
