Subject: [PATCH 0/8] Leave child suspended when step over parent
Date: Fri, 19 Feb 2016 14:36:00 -0000 [thread overview]
Message-ID: <1455892594-2294-1-git-send-email-yao.qi@linaro.org> (raw)
When I teach GDBserver on arm-linux handling single step requested by
GDB (via vCont;s), I see a GDBserver internal error. I can also
reproduce this internal error on mainline GDBserver as well. In short,
the internal error is triggered by the child's incorrect suspend count,
because it is spawned by the parent and GDBserver is stepping the
parent over a breakpoint. See more in patch #1.
Patches #2 to #8 are about refactoring and extending test case to
reproduce the internal error I've see.
Regression tested on x86_64-linux.

Yao Qi (8):
[GDBserver] Leave child suspended when step over parent
Refactor gdb.base/disp-step-syscall.exp for general step over test
Use loop in disp-step-fork.c and disp-step-vfork.c
Step over syscalll insn with disp-step on and off
Step over fork/vfork syscall insn in gdbserver
Reformat disp-step-syscall.exp
Rename disp-step-syscall.exp to step-over-syscall.exp
New test about step over clone syscall
