tberghammer added a comment. I don't fully understand how the ptrace API works in the aarch64 Linux kernel but based on my experiments the arm specific ptrace calls aren't working (returning -EIO for a reason unknown to me at the moment). Because of this, the current watchpoint implementation ins't working when aarch64 lldb-server is debugging an arm32 inferior. I also tried to change the implementation to use ReadRegisterSet(NT_ARM_HW_WATCH) but it wasn't working either most likely because NT_ARM_HW_WATCH isn't listed as a register set in http://lxr.free-electrons.com/source/arch/arm64/kernel/ptrace.c#L853
I will keep investigating how can we set arm watchpoints from an aarch64 kernel but I would appreciate any suggestion if you have one. http://reviews.llvm.org/D15533 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
