This month I\'ve finally finished upstreaming NetBSD support in ASan and UBsan.
For better coverage of the sanitizers and on user request I\'ve ported libFuzzer and SafeStack.
There are mutual dependencies between the compiler-rt features.
NetBSD after sorting out msan and tsan shall get all the remaining ones enabled.

In the last month I started with upstream of the code for sanitizers:
the common layer and ubsan.
I worked also on the elimination of unexpected failures in LLVM and Clang.
I\'ve managed to achieve, with a pile of local patches,
the number of 0 unexpected bugs within LLVM (check-llvm) and 3 unexpected bugs within Clang (check-clang)
(however [...]

LLVM asan and ubsan on NetBSD
Over the last 30 days I was focusing on getting the environment to enable LLVM sanitizers and the Clang compiler on NetBSD.
Meanwhile I pushed forward generic parts that were needing enhancements around pkgsrc and LLVM in general to ease the future LLDB work.

New home for the repository conversio...
Hello all,
the repository conversion setup for NetBSD CVS -> Fossil -> Git
has found a new home. Ironically, on former cvs.NetBSD.org hardware.
This provides a somewhat faster conversion cycle as well as removing
anoncvs.NetBSD.org from the process. This should avoid occasional
problems with incomplete syncs. Two other changes have bee [...]

This month I started to work on correcting of the ptrace(2) layer,
as test suites used to trigger failures on the kernel side.
This finally ended up sanitizing the LLDB runtime as well, addressing
LLDB and NetBSD userland bugs.
It turned out that more bugs were unveiled and this is not the final report on LLDB.

Last month I have worked on features of the Process Plugin on NetBSD and support for threads in core(5) files.
What has been done in NetBSD
I\'ve managed to achieve the following accomplishments:
Introduction of PT_SETSTEP and PT_CLEARSTEP
This allows to:
singlestep particular threads,
combine PT_STEP with PT_SYSCALL,

A feature set for debugging NetBSD applications (without threads) has been merged with upstream LLDB!
The number of passing tests this month has been increased from 267/1235 to 622/1247.
This is +133% within one month and approximately 50% of successfully passed tests in total!
