Re: [lldb-dev] did anyone konw LLDB support lldb + openocd to run dotest.py in bare board like ARM or other non-x86 architecture?

[Ramana via lldb-dev]

These sort of issues I have faced in the past and in my case the
reason was I used the incorrect host triple while building LLDB (LLVM
etc).

Example:
   Assuming you are using GCC/G++ compiler to build LLVM+LLDB, I would
set the LLVM_HOST_TRIPLE to the one used in the library path and not
essentially that of the 'Target' in 'gcc -v'.

$ gcc -v

Target: i686-linux-gnu
...
$ ldd /usr/bin/gcc

libc.so.6 => /lib/i386-linux-gnu/libc.so.6
..

Now, I would set LLVM_HOST_TRIPLE to i386-linux-gnu but not i686-linux-gnu.

See if that works for you.

[lldb-dev] Sanitizers update: The LLVM Thread Sanitizer has been ported to NetBSD

[Kamil Rytarowski via lldb-dev]

Hello,

I've finished the LLVM TSan porting:

https://blog.netbsd.org/tnf/entry/the_llvm_thread_sanitizer_has

Next goal:
Finish MSan followed by the switch to LLDB/NetBSD corrections.

Have you been able to run lldb under any sanitizers yet?

Re: [lldb-dev] Sanitizers update: The LLVM Thread Sanitizer has been ported to NetBSD

[Kamil Rytarowski via lldb-dev]

Yes, I can run LLDB under at least ASan and TSan.

Pity, the backend part (lldb-server) broke after refactoring the code in
recent months. I'm observing an early NULL pointer deference from NetBSD
Process Plugin - this is unrelated to the previous stability bugs that
inspired me to get the sanitizers aboard.

I will be back to LLDB once I will finish MSan.

You need to create the lldb_codesign code signing certificate by following the
instructions at:

svn cat http://llvm.org/svn/llvm-project/lldb/trunk/docs/code-signing.txt

Reopening. The error message is particularly cryptic, in particular for
somebody who doesn't understand how the code signing mechanism works.
FWIW, I think this, rather than failing at link time can fail at configure time
(if possible). Then, it should point to the instructions you linked.

[lldb-dev] [Bug 35488] New: [Meta] tracking test suite failure on Mac OS

[via lldb-dev]

https://bugs.llvm.org/show_bug.cgi?id=35488

Bug ID: 35488
   Summary: [Meta] tracking test suite failure on Mac OS
   Product: lldb
   Version: unspecified

I ran lldb on a pristine, freshly installed (stock) Mac OS High Sierra.
This is the current status of the test suite (ran through `ninja check-lldb`):

===
Test Result Summary
===
Test Methods:   2659
Reruns:6
Success:1682
Expected Failure:100
Failure:   8
Error:   510
Exceptional Exit:  0
Unexpected Success:   37
Skip:320
Timeout:   2
Expected Timeout:  0

This status makes slightly harder to push non-trivial changes in lldb, because
it's not entirely obvious how to track regressions. Let's open this PR to keep
track.
