Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
- Add a new KTR_STRUCT_ARRAY ktrace record type which dumps an array of
structures.
The structure name in the record payload is preceded by a size_t
containing the size of the individual structures. Use this to
replace the previous code that dumped the kevent arrays dumped for
kevent(). kdump is now able to decode the kevent structures rather
than dumping their contents via a hexdump.
One change from before is that the 'changes' and 'events' arrays are
not marked with separate 'read' and 'write' annotations in kdump
output. Instead, the first array is the 'changes' array, and the
second array (only present if kevent doesn't fail with an error) is
the 'events' array. For kevent(), empty arrays are denoted by an
entry with an array containing zero entries rather than no record.
- Move kevent decoding tables from truss to libsysdecode.
This adds three new functions to decode members of struct kevent:
sysdecode_kevent_filter, sysdecode_kevent_flags, and
sysdecode_kevent_fflags.
kdump uses these helper functions to pretty-print kevent fields.
- Move structure definitions for freebsd11 and freebsd32 kevent
structures to <sys/event.h> so that they can be shared with userland.
The 32-bit structures are only exposed if _WANT_KEVENT32 is defined.
The freebsd11 structures are only exposed if _WANT_FREEBSD11_KEVENT is
defined. The 32-bit freebsd11 structure requires both.
- Decode freebsd11 kevent structures in truss for the compat11.kevent()
system call.
- Log 32-bit kevent structures via ktrace for 32-bit compat kevent()
system calls.
- While here, constify the 'void *data' argument to ktrstruct().

Add notes to each of these that specifically state that results are

We started out having Linux compatible libefivar interfaces. This was
in anticipation of porting the GPL'd efibootmgr to FreeBSD via a
port. However, since we need that functionality in the base, that port
isn't going to happened. It also appears that efivar is a private
library that's not used much outside a command line util and
efibootmgr. Reduce compatibility with the Linux version a little by
removing the mode parameter to efi_set_variable (which was unused on
FreeBSD, and not set to something useful in the code we'd
written). Also remove some efi error routines that were never
implemented and existed only to placate early GPL efibootmgr porting
experiments.

CPUTYPE (apparently) isn't defined in non-cross-builds, which caused

- Define TARGET_CPUARCH and use in libclang_rt as the basis for CRTARCH
When cross-compiling, the wrong architecture was being embedded in the
libclang_rt binary filenames. It should be based on TARGET_ARCH (target), not
MACHINE_ARCH (host).
If TARGET_ARCH isn't defined (host-builds), fallback to MACHINE_ARCH.
- Define CRTARCH to armhf when TARGET/TARGET_ARCH are set to arm/armv[67]
TARGET_ABI/TARGET_CPU in Makefile.inc1 sets the ABI to gnueabihf, which
affects the clang lookup path per `getArchNameForCompilerRTLib(..)` in
contrib/llvm/tools/clang/lib/Driver/ToolChain.cpp, so chase clang and
Linux's assumed naming convention for hard-float arm architectures.
CROSSENV (in Makefile.inc1) sets CPUTYPE/MACHINE(_ARCH)? to the
TARGET*-relevant values when building the `libraries` target, so test
those variables instead.
- Add OLD_FILES/OLD_LIBS entries for TARGET/TARGET_ARCH == arm/armv[67]. This
impacts only arm/armv6 and arm/armv7.
