from ChangeLog:
(most of this by rillig@)
o lots of style and white-space cleanup
o lots more unit tests for variable modifiers
o simplified description of some functions
o str.c: refactor Str_Match
o var.c: debugging output for :@
constify VarModify parameter
fix :hash modifier on 16-bit platforms
remove unnecessary forward declarations
refactor ApplyModifier_SysV to have less indentation
simplify code for :E and :R
clean up code for :H and :T
refactor ApplyModifiers
* var.c: we need stdint.h on some platforms to get uint32_t
* unit-test/Makefile: we need to supress the specific error
for RE substitution error in modmisc, since it varies accross
different OS.
from ChangeLog:
o cond.c: do not eval unnecessary terms of conditionals.
o meta.c: report error if lseek in filemon_read fails
o str.c: performance improvement for Str_Match for multiple '*'
o dieQuietly: supress the failure output from make
when failing node is a sub-make or a sibling failed.
This cuts down greatly on unhelpful noise at the end of
build log. Disabled by -dj or .MAKE.DIE_QUIETLY=no
o unit test for :Or
Changes since 20181221 are mostly portability related
hence the large gap in versions imported.
There are however some bug fixes, and a rework of filemon handling.
In NetBSD make/filemon/filemon_ktrace.c allows use of fktrace
and elimination of filemon(4) which has not had the TLC it needs.
FreeBSD filemon(4) is in much better shape, so bmake/filemon/filemon_dev.c
allows use of that, with a bit less overhead than the ktrace model.
Summary of changes from ChangeLog
o str.c: empty string does not match % pattern
plus unit-test changes
o var.c: import handling of old sysV style modifier using '%'
o str.c: refactor brk_string
o meta.c: meta_oodate, CHECK_VALID_META is too aggressive for CMD
a blank command is perfectly valid.
o meta.c: meta_oodate, check for corrupted meta file
earlier and more often.
* meta.c: meta_compat_parent check for USE_FILEMON
patch from Soeren Tempel
o meta.c: fix compat mode, need to call meta_job_output()
o job.c: extra fds for meta mode not needed if using filemon_dev
o meta.c: avoid passing NULL to filemon_*() when meta_needed()
returns FALSE.
o filemon/filemon_{dev,ktrace}.c: allow selection of
filemon implementation. filemon_dev.c uses the kernel module
while filemon_ktrace.c leverages the fktrace api available in
NetBSD. filemon_ktrace.c can hopefully form the basis for
adding support for other tracing mechanisms such as strace on
Linux.
o meta.c: when target is out-of-date per normal make rules
record value of .OODATE in meta file.
o parse.c: don't pass NULL to realpath(3)
some versions cannot handle it.
o parse.c: ParseDoDependency: free paths rather than assert
plus more unit-tests
o parse.c: ParseVErrorInternal use .PARSEDIR
and apply if relative, and then use .PARSEFILE
for consistent result.
o var.c: avoid SEGFAULT in .unexport-env
when MAKELEVEL is not set
Of relevance:
o job.c: skip polling job token pipe
o parse.c: be more cautious about detecting depenency line
rather than sysV style include.
also in mk:
* dirdeps.mk: include local.dirdeps-build.mk when .MAKE.LEVEL > 0
ie. we are building something.
* FILES: add dirdeps-options.mk to deal with optional DIRDEPS.
* ldorder.mk: describe how to use LDORDER_EXTERN_BARRIER
if needed.

2017-10-28 Simon J. Gerraty <sjg@bad.crufty.net>
* VERSION: 20171028
Merge with NetBSD make, pick up
o main.c: ignore empty MAKEOBJDIR
* Makefile.config.in:
make @prefix@ @machine*@ and @default_sys_path@ defaults.
2017-10-05 Simon J. Gerraty <sjg@bad.crufty.net>
* VERSION: 20171005
* unit-tests/dotwait.mk: redirect stderr through pipe for more
consistent result on some platforms.
2017-08-13 Simon J. Gerraty <sjg@bad.crufty.net>
* machine.sh: entry for AIX
2017-08-12 Simon J. Gerraty <sjg@bad.crufty.net>
* VERSION (_MAKE_VERSION): Move the setting of _MAKE_VERSION
to a file that can be included by configure as well as make.
This allows configure to set set _MAKE_VERSION in make-bootstrap.sh
2017-08-10 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20170810
Merge with NetBSD make, pick up
o meta.c: if target is in subdir we only need subdir name in
meta_name.
Several misc cleanups, refactor main() to reduce size.
Adds -v option to always fully expand variables (only interesting to NetBSD)
And in particular (from ChangeLog):
o meta.c: ensure command output in meta file has ending newline
even when filemon not being used.
When matching ${.MAKE.META.IGNORE_PATTERNS} do not use
pathname via ':L' since any ':' in pathname breaks that.
Instead set a '${.p.}' to pathname in the target context and
use that.

2016-12-12 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20161212
Merge with NetBSD make, pick up
o main.c: look for obj.${MACHINE}-${MACHINE_ARCH} too.
2016-12-09 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20161209
Merge with NetBSD make, pick up
o main.c: cleanup setting of .OBJDIR
o parse.c: avoid coredump from (var)=val
2016-11-26 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20161126
Merge with NetBSD make, pick up
o make.c: Make_OODate: report src node name if path not set
2016-09-26 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20160926
Merge with NetBSD make, pick up
o support for .DELETE_ON_ERROR: (remove targets that fail)

mk/ChangeLog
2016-12-12 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20161212
* meta2deps.py: set pid_cwd[pid] when we process 'C'hdir,
rather than when we detect pid change.
2016-12-07 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20161207
* meta.stage.mk: add stage_as_and_symlink for staging packages.
We build foo.tgz stage_as foo-${VERSION}.tgz but want to be able
to use foo.tgz to reference the latest staged version - so we
make foo.tgz a symlink to it.
Using a target to do both operations ensures we stay in sync.
2016-11-26 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20161126
* dirdeps.mk: set DIRDEPS_CACHE before we include local.dirdeps.mk
so it can add dependencies.
2016-10-10 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk: set DEP_* before we expand .MAKE.DEPENDFILE_PREFERENCE
do that they can influence the result correctly.
* dirdeps.mk (${DIRDEPS_CACHE}): make sure we pass on TARGET_SPEC
* dirdeps.mk: Add ONLY_TARGET_SPEC_LIST and NOT_TARGET_SPEC_LIST
similar to ONLY_MACHINE_LIST and NOT_MACHINE_LIST
2016-10-05 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk: remove dependence on jot (normal situations anyway).
Before we read another Makefile.depend* set DEP_* vars from
_DEP_TARGET_SPEC in case it uses any of them with :=
When bootstrapping, trim any ,* from extention of chosen _src
Makefile.depend* to get the machine value we subst for.
2016-09-30 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk: use TARGET_SPEC_VARS to qualify components added to
DEP_SKIP_DIR and DEP_DIRDEPS_FILTER
* sys.mk: extract some bits to sys.{debug,vars}.mk
for easier re-use by others.
2016-09-23 Simon Gerraty <sjg@sjg-mba13>
* lib.mk: Use ${PICO} for extension for PIC objects.
default to .pico (like NetBSD) safe on case insensitive filesystem.
2016-08-19 Simon J. Gerraty <sjg@bad.crufty.net>
* meta.sys.mk (META_COOKIE_TOUCH): use ${.OBJDIR}/${.TARGET:T} as default
Interesting changes:
o meta.c: move handling of .MAKE.META.IGNORE_* to meta_ignore()
so we can call it before adding entries to missingFiles.
Thus we do not track files we have been told to ignore.
o meta_oodate: apply .MAKE.META.IGNORE_FILTER (if defined) to
pathnames, and skip if the expansion is empty.
Useful for dirdeps.mk when checking DIRDEPS_CACHE.
o meta.c: remove all missingFiles entries that match a deleted
dir.
o main.c: set .ERROR_CMD if possible.
Interesting items from ChangeLog:
o cached_realpath(): avoid hitting filesystem more than necessary.
o meta.c: refactor need_meta decision, add knobs for
missing meta file and filemon data wrt out-of-datedness.
o meta.c: missing filemon data is only relevant if we read a
meta file.
Also do not return oodate for a missing metafile if gn->path
points to .CURDIR
Interesting changes (from ChangeLog):
o meta.c: ignore paths that match .MAKE.META.IGNORE_PATTERNS
this is useful for gcov builds.
o propagate errors from filemon(4).
o meta.c: apply realpath() before matching against metaIgnorePaths
o allow makefile to set .MAKE.JOBS
Relevant items from ChangeLog:
o [Makefile.in:] protect syntax that only bmake parses correctly.
o compat.c: ignore empty commands - same as jobs mode.
o make.1: document meta chars that cause use of shell
