and 3.4 to generate dependency files for the '.inc.h' files generated
from .td files, and .sinclude those dependency files in clang.build.mk.
This will make future incremental builds of lib/clang and usr.bin/clang
work correctly, whenever any of the .td files get modified.
Note that this will not fix any problems with incremental builds from
*before* this revision, since there will not yet be any generated
dependency files. A quick workaround is to run the following:
find /usr/obj -type f -name '*.inc.h' | xargs rm
and then a regular incremental buildworld (e.g. with -DNO_CLEAN).

This has not added a lot of value when debugging bhyve issues while greatly
increasing the time and space required to store the core file.
Passing the "-C" option to bhyve(8) will change the default and dump guest

H_SAVE_FP is similar to H_SAVE but operates on a FILE* instead of a filename.
This is useful when operating in capability mode.

actual file storing the semaphore object is different from the file
created on the first open. Store the file st_dev and st_ino members
of the struct stat in the semaphore structure on open, and compare
them with the attributes of the opened file to detect unlink and
re-creation.
This fixes an issue of sem_unlink(3) failing to flush the named entry
in the semaphore list for the current or remote process, making
sem_unlink(3) not correctly operating if the unlinked semaphore is
still opened.

by adding an argument to the VM_SUSPEND ioctl that specifies how the virtual
machine should be suspended, viz. VM_SUSPEND_RESET or VM_SUSPEND_POWEROFF.
The disposition of VM_SUSPEND is also made available to the exit handler
via the 'u.suspended' member of 'struct vm_exit'.
This capability is exposed via the '--force-reset' and '--force-poweroff'
arguments to /usr/sbin/bhyvectl.

since they don't have an easily recognizable signature, was if they
were the default. This commit rewrites crypt_set_format(3) etc to
address this:
- Use a pointer instead of an index to identify the default format.
This pointer is initialized at compile time to point to the first
first element in the list of supported formats, eliminating the
need for crypt_setdefault(). Using a pointer also simplifies
iterating through the list.
- Associate DES with the magic string "_", which takes care of the
Extended DES format.
- Finally, as a special case, if the salt does not match any known
magic string but matches ^[./0-9A-Za-z]{13}$, it is assumed to be a
DES password and is passed on to crypt_des().

An execute-only fd (opened with O_EXEC) allows neither read() nor write()
and is therefore incompatible with all stdio modes. Therefore, the [EINVAL]
error applies.
Also adjust the similar check in freopen() with a NULL path, even though
this checks an fd which is already from a FILE.
If realpath() is called on pathnames like "/dev/null/." or "/dev/null/..",
it should fail with [ENOTDIR]. Pathnames like "/dev/null/" already failed as
they should.
Also, put the check for non-directories after lstatting the previous
component instead of when the empty component (consecutive or trailing
slashes) is detected, saving an lstat() call and some lines of code.

uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.
kqueue(2) already supports EVFILT_PROC. Add an EVFILT_PROCDESC that
behaves the same, but operates on a procdesc(4) instead. Only implement
NOTE_EXIT for now. The nice thing about NOTE_EXIT is that it also
returns the exit status of the process, meaning that we can now obtain
this value, even if pdwait4(2) is still unimplemented.
Notes:
- Simply reuse EVFILT_NETDEV for EVFILT_PROCDESC. As both of these will
be used on totally different descriptor types, this should not clash.
- Let procdesc_kqops_event() reuse the same structure as filt_proc().
The only difference is that procdesc_kqops_event() should also be able
to deal with the case where the process was already terminated after
registration. Simply test this when hint == 0.
- Fix some style(9) issues in filt_proc() to keep it consistent with the
newly added procdesc_kqops_event().
- Save the exit status of the process in pd->pd_xstat, as we cannot pick
up the proctree_lock from within procdesc_kqops_event().
