files produced by recent versions of clang.
In BFD's elf_create_symbuf() function, the size of the symbol buffer
('ssymbuf') is not calculated correctly, and the initial value for the
'ssym' variable is off by one, since 'ssymbuf' has shndx_count + 1
members.

When the armv6 support was imported from a project branch, this complex
conditional logic and related #define'd values came along, but it's really
not clear what the intent of it all was. The effect, however, was that
OSABI was always set to zero, which is "UNIX System V ABI". Having the wrong
value there causes pkg(8) to avoid looking inside arm elf binaries to
determine shared-lib required/provides info for packaging.
If the output object is not an ELF file, choose an arbitrary ELF format
for the intermediate file. srec, ihex and binary formats are independent
of class, endianness and machine type so these choices do not affect the
output.

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.

Unlike the version submitted by cem in OneFS, this version uses a scratch file

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.

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.

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.)
