X86. This prevents problems with some functions using TLS, such as in
jemalloc, and which was the cause for Address Sanitizer crashes. The
correct fix is still being discussed upstream.
This would have printed an unknown RISC-V relocation type as a SPARC

as otherwise platforms with strict alignment would break. It's unclear
to me if there's also a problem with access to the address list following
the structure. However we never copied the address list after the structure
and thus are pointing at random memory. For now just use a pointer to the
original memory for accessing the address list making it at least work on
platforms with weak memory access.

Fix grep_test:recurse when /tmp is either zfs or tmpfs. The test was
relying on an implicit ordering of directory recursion which happens
to be true when using UFS. grep's specification requires no such
ordering. The solution is to ignore the order of grep's results.

Require root privileges in order to set the sysctl
Add allow_sysctl_side_effects to require.config as this test is now adjusting
sysctls that can affect the global system state
Unlike the version submitted by cem in OneFS, this version uses a scratch file
to save/restore the previous value of the sysctl. I _really_, _really_ wish
there were better hooks in atf/kyua for per test suite setup/teardown -- using
a file is kludgy, but it's the best I can do to avoid situations where (for
instance), sysctl(3) may fail and drop a core outside the kyua sandbox.
Based on a patch submitted by cem, but modified to take business logic out of
ATF_TP_ADD_TCS(3).

Fix PR26134: When substituting into default template arguments, keep
CurContext unchanged.
Or, do not set Sema's CurContext to the template declaration's when
substituting into default template arguments of said template
declaration.
If we do push the template declaration context on to Sema, and the
template declaration is at namespace scope, Sema can get confused and
try and do odr analysis when substituting into default template
arguments, even though the substitution could be occurring within a
dependent context.
I'm not sure why this was being done, perhaps there was concern that
if a default template argument referred to a previous template
parameter, it might not be found during substitution - but all
regression tests pass, and I can't craft a test that would cause it
to fails (if some one does, please inform me, and i'll craft a
different fix for the PR).
This patch removes a single line of code, but unfortunately adds more
than it removes, because of the tests. Some day I still hope to
commit a patch that removes far more lines than it adds, while
leaving clang better for it ;)
Sorry that r253590 ("Change the expression evaluation context from
Unevaluated to ConstantEvaluated while substituting into non-type
template argument defaults") caused the PR!
This fix will be merged to the upstream release_38 branch soon, but we
need it now, to fix a failure in the databases/sfcgal port.

[DwarfDebug] Don't merge DebugLocEntries if their pieces overlap

Later in DWARF emission we check that DebugLocEntries have

Stop increasing alignment of externally-visible globals on ELF
platforms.
With ELF, the alignment of a global variable in a shared library will
get copied into an executables linked against it, if the executable even
accesss the variable. So, it's not possible to implicitly increase
alignment based on access patterns, or you'll break existing binaries.
This happened to affect libc++'s std::cout symbol, for example. See
thread: http://thread.gmane.org/gmane.comp.compilers.clang.devel/45311
(This is a re-commit of r257719, without the bug reported in
PR26144. I've tweaked the code to not assert-fail in
enforceKnownAlignment when computeKnownBits doesn't recurse far enough
to find the underlying Alloca/GlobalObject value.)

llvm's LinkAllPasses.h. This caused some of the calls not to be
emitted, if the optimization level was -O2 or higher.
Conversely, if you used -O1 or lower, calls to e.g. RunningOnValgrind()
would be emitted, leading to link failures, because we did not include
Valgrind.cpp into libllvmsupport. Therefore, add it unconditionally.

gdb. The lldb debug tuning is not yet grokked completely by our ELF
manipulation tools.
