The move to /usr/include/private prefixed paths seems to require a bit more
effort in order to compile programs.
Install the headers to /usr/include/private/g{mock,test}/... and automatically
include /usr/include/private in GTESTS_CXXFLAGS to make compilation seamless. I
will work on the more global problem later with @bdrewery.
Long story short, some of the tests were failing because they expected either
dynamic_cast or RTTI to be functional and it wasn't.
Move all common CXXFLAGS out to googletest.test.inc.mk and reference it from
googletest.test.mk and .../googletest/Makefile.inc
The key difference is that some of the programs were previously being compiled
and installed as tests, which is incorrect. Treat them like helpers instead.
My previous work to integrate these tests was incomplete/incorrect, because I
misunderstood how the cmake macros worked.
This addresses items with the gtest tests, which in turn fixes test compilation
and adds more tests which I had previously missed.
Due to an unknown issue with gtest_stress_test, I had to add pthread to LIBADD,
even though I shouldn't have added it to that (it was failing to link -lpthread
to libprivategtest.a). Add a XXX comment to note that something's awry there
and deserves additional investigation.
The former is from googletest.test.mk, whereas the latter is from plain.test.mk.
As noted in r344328, Kyua will adopt more native GoogleTest support. Thus, it's
more desirable to make the test interface more of an opaque blackbox for the
testcase implementer.
- Look up the corresponding non-*_main libraries via LDFLAGS using the
directories provided in src.libnames.mk. This will allow the libraries to
be built in the "make libraries" phase of buildworld.
- gtest_main relies on gtest, but didn't explicitly call out the dependency
in `LIBADD`. Fill in this missing blank.
They are supporting libraries and as such, will need to be built/installed
when MK_TESTS == no during buildworld, i.e., the "make libraries" phase.
Otherwise, dependent components cannot rely on the libraries, like
`cddl/usr.sbin/zfsd/tests`.
These libraries don't compile on non-C++-11 capable compilers, e.g., g++ 4.2.1
and its corresponding implementation of the c++ library, i.e., libstdc++.
Blacklist compilation on all non-C++-11 capable compilers and give others the
option of opting out of building/installing gmock/gtest via MK_GOOGLETEST.
This option is controlled by MK_CXX and MK_TESTS, as ATF compilation is.

back to the lever before r343030. For 64-bit machines reduce it slightly,
too. Together with r343030 I bumped the limit up to the value we use at
Netflix to serve 100 Gbit/s of sendfile traffic, and it probably isn't a
good default.
Provide a loader tunable to change vnode pager pbufs count. Document it.
Building binaries as PIE allows the executable itself to be loaded at a
random address when ASLR is enabled (not just its shared libraries).
With this change PIE objects have a .pieo extension and INTERNALLIB
libraries libXXX_pie.a.
MK_PIE is disabled for some kerberos5 tools, Clang, and Subversion, as
they explicitly reference .a libraries in their Makefiles. These can
be addressed on an individual basis later. MK_PIE is also disabled for
rtld-elf because it is already position-independent using bespoke
Makefile rules.
Currently only dynamically linked binaries will be built as PIE.

be_destroy is documented to recursively destroy a boot environment. In the
case of snapshots, one would take this to mean that these are also
recursively destroyed. However, this was previously not the case.
be_destroy would descend into the be_destroy callback and attempt to
zfs_iter_children on the top-level snapshot, which is bogus.
Our alternative approach is to take note of the snapshot name and iterate
through all of fs children of the BE to try destruction in the children.
The -o option is also fixed to work properly with deep BEs. If the BE was
created with `bectl create -e otherDeepBE newDeepBE`, for instance, then a
recursive snapshot of otherDeepBE would have been taken for construction of
newDeepBE but a subsequent destroy with BE_DESTROY_ORIGIN set would only
clean up the snapshot at the root of otherDeepBE: ${BEROOT}/otherDeepBE@...
The most recent iteration instead pretends not to know how these things
work, verifies that the origin is another BE and then passes that back
through be_destroy to DTRT when snapshots and deep BEs may be in play.

nvpair_remove_nvlist_array (NV_TYPE_NVLIST_ARRAY case): free the chain
of nvpairs (as resetting it prevents nvlist_destroy() from freeing it).
Note: freeing the chain in nvlist_destroy() is not sufficient, because

Currently origin snapshots are left behind when a BE is destroyed, whether
it was an auto-created snapshot or explicitly specified via, for example,
`bectl create -e be@mysnap ...`.
Removing it automatically could be argued as a POLA violation in some
circumstances, so provide a flag to be_destroy for it. An accompanying
option will be added to bectl(8) to utilize this.
Some minor style/consistency nits in the affected areas also addressed.

[X86] Add FPSW as a Def on some FP instructions that were missing it.
Pull in r353141 from upstream llvm trunk (by Craig Topper):
[X86] Connect the default fpsr and dirflag clobbers in inline
assembly to the registers we have defined for them.
Summary:
We don't currently map these constraints to physical register numbers
so they don't make it to the MachineIR representation of inline
assembly.
This could have problems for proper dependency tracking in the
machine schedulers though I don't have a test case that shows that.

Pull in r353489 from upstream llvm trunk (by Craig Topper):
[X86] Add FPCW as a register and start using it as an implicit use on
floating point instructions.
Summary:
FPCW contains the rounding mode control which we manipulate to
implement fp to integer conversion by changing the roudning mode,
storing the value to the stack, and then changing the rounding mode
back. Because we didn't model FPCW and its dependency chain, other
instructions could be scheduled into the middle of the sequence.
This patch introduces the register and adds it as an implciit def of
FLDCW and implicit use of the FP binary arithmetic instructions and
store instructions. There are more instructions that need to be
updated, but this is a good start. I believe this fixes at least the
reduced test case from PR40529.

When libthr is statically linked into the binary, order of the
constructors execution is not deterministic. It is possible for the
application constructor to use pthread_mutex_* functions before the
libthr initialization was done.
Handle it by:
- making thr_malloc.c locking functions operational when curthread is not
yet set;
- making __thr_malloc_init() idempotent, allowing more than one call to it;
- unconditionally calling __thr_malloc_init() before initializing
a process-private mutex.
