I've managed to unbreak the LLDB debugger as much as possible with the current kernel and hit problems with ptrace(2) that are causing issues with further work on proper NetBSD support. Meanwhile, I've upstreamed all the planned NetBSD patches to sanitizers and helped other BSDs to gain better or initial support. http://blog.netbsd.org/tnf/entry/lldb_restoration_and_return_to Plan for the next milestone With the approaching NetBSD 8.0 release I plan to finish backporting a few changes there from HEAD: - Remove one unused feature from ptrace(2), PT_SET_SIGMASK & PT_GET_SIGMASK. I've originally introduced these operations with criu/rr-like software in mind, but they are misusing or even abusing ptrace(2) and are not regular process debuggers. I plan to remove this operation from HEAD and backport this to NetBSD-8(BETA), before the release, so no compat will be required for this call. Future ports of criu/rr should involve dedicated kernel support for such requirements. - Finish the backport of _UC_MACHINE_FP() to NetBSD-8. This will allow use of the same code in sanitizers in HEAD and NetBSD-8.0. - By popular demand, improve the regnsub(3) and regasub(3) API, adding support for more or less substitutions than 10. Once done, I will return to ptrace(2) debugging and corrections.
