intended for debugging and diagnostic output), just inspect the spelling
to check for specific prefixes in drectve section flags.
In addition to being significantly cheaper and not relying on
a debugging interface, this also avoids creating a temporary string and
binding it to StringRef variable. We then went on to access it after the
memory had been deallocated.
This bug too was caught by ASan. I love ASan so much. =]

More important than any performance concerns, the code was dropping the
temporary string on the floor after assigning it to a StringRef, and
then used the StringRef later. Caught by running the LLD tests under
ASan.

On discussing this with Nick, it looks like the StubAtoms
that contain a lazyImmediate reference kind should be null
and the location needs to be fixed up later with some value
that is an offset into the __LINKEDIT segment.
The drawback is that it allows yaml files with references
that expect a target to be considered without one.
This results in bad yaml files that would need to be handled
in the YAML Reader.
Inorder to fix this, the Stub Atoms use a dummy target such
as itself.

so try PATH next. Assume it is sane enough to cover the usual system
bash locations too, but the old list is not good enough for NetBSD.

If multiprocessing was requested, detected as available and subsequently failed
to initialize it's worth letting the user know about it before falling back to
threads.
This condition can arise in certain OpenBSD / FreeBSD Python versions.
llvm-svn: 193465
This should be a better fix for lit multiprocessing failures, replacing the
OpenBSD and FreeBSD workarounds in r193413 and r193457.

We only considered FieldDecl and CXXMethodDecl as appropriate which
would cause us to believe the IndirectFieldDecl corresponded to an
argument of it's field type instead of a pointer-to-member type.
This fixes PR17696.

I saw the case that 'native' was mis-enabled when x86_64-pc-win32 on x86_64-linux.
FIXME: Consider cases that target can be executed even if host_triple were different from target_triple.

Speculative quick fix based on clang-X86_64-freebsd output:
File "/usr/local/lib/python2.6/multiprocessing/synchronize.py", line 33, in <module>
" function, see issue 3770.")
ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.

We could certainly be more precise in many of our diagnostics, but before we
were printing "Assuming x is && y", which is just ridiculous.

/merge:<from>=<to> option makes the linker to combine "from" section to "to"
section. This patch is to parse the option. The actual feature will be
implemented in a subsequent patch.

Introduce a new boolean setting enable-auto-oneliner
This setting if set to false will force LLDB to not use the new compact one-line display
By default, one-line mode stays on, at least until we can be confident it works.
But now if it seriously impedes your workflow while it evolves/it works wonders but you still hate it, there's a way to turn it off

This moves away from creating the symbolizer object and initializing the
external symbolizer as separate steps. Those steps now always take place
together.
Sanitizers with a legacy requirement to specify their own symbolizer path
should use InitSymbolizer to initialize the symbolizer with the desired
path, and GetSymbolizer to access the symbolizer. Sanitizers with no
such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for
initialization.
The symbolizer interface has been made thread-safe (as far as I can
tell) by protecting its member functions with mutexes.
Finally, the symbolizer interface no longer relies on weak externals, the
introduction of which was probably a mistake on my part.
