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.

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

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

Conversely, if you used -O1 or lower, calls to e.g. RunningOnValgrind()

The current code for encoding a netbios name converts each byte to a 16-bit
value and stores the result by casting a char* to u_short*, resulting in
alignment faults on strict-alignment platforms.
This change reimplements the encoding routine using only byte accesses to
memory. There is no particular reason to work with 16-bit values just
because the encoding process creates two bytes of output for every byte of
input. Working a byte at at time also avoids endian problems for big-endian
platforms.

system call information such as system call arguments. Initially this
will consist of pulling duplicated code out of truss and kdump though it
may prove useful for other utilities in the future.
This commit moves the shared utrace(2) record parser out of kdump into
the library and updates kdump and truss to use it. One difference from
the previous version is that the library version treats unknown events
that start with the "RTLD" signature as unknown events. This simplifies
the interface and allows the consumer to decide how to handle all
non-recognized events. Instead, this function only generates a string
description for known malloc() and RTLD records.
