I don't know what's going on, I moved on to other tasks for now as this does not stop other features and the general functionality of watchpoints, even if they are incorrectly reported. > * floating point registers support, Functional and pending upstream: https://reviews.llvm.org/D32080 We need to add XSAVE ans XSAVEOPT into ptrace(2) and apparently into mcontext. As of now AVX and similar registers are hidden from the mentioned interfaces. > * enhance core(5) and make it work for multiple threads Functional and pending upstream: https://reviews.llvm.org/D32149 In general the original code was buggy and I decided to go for a custon NetBSD-specific function to decode thread context notes. As doing it in the same loop function with Linux would produce monstrous code. > * introduce PT_SETSTEP and PT_CLEARSTEP in ptrace(2) Committed into the kernel. > * research F_GETPATH in fcntl(2) Currently we decided to not introduce this. The general feeling of the core developers is to handle this functionality on the LLDB side (in case it will be needed on NetBSD). The Linux specific fallback (reading /proc) is not acceptable. > > On the second half of this month I will move on to: > * support threads in the NetBSD Process Plugin > High time to switch to this task now. > > Upstream LLVM+Clang+LLDB version r. 299109 (no local patches) verification*: > > =================== > Test Result Summary > =================== > Test Methods: 1247 > Reruns: 0 > Success: 622 > Expected Failure: 23 > Failure: 79 > Error: 97 > Exceptional Exit: 0 > Unexpected Success: 1 > Skip: 424 > Timeout: 1 > Expected Timeout: 0 > > http://netbsd.org/~kamil/lldb/check-lldb-r299109-2017-04-04.txt > > * I'm still using pkgsrc-wip and it might affect the score compared to > clean out of pkgsrc build. > There is a minimal increment of successfully passed tests. Partly due to the stop status reported for watchpoints.
