From ChangeLog
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)
2016-09-26 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile MAN: tweak .Dt to match ${PROG}
mk/ChangeLog
2016-12-12 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20161212
* meta2deps.py: set pid_cwd[pid] when we process 'C'hdir,
rather than when we detect pid change.
2016-12-07 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20161207
* meta.stage.mk: add stage_as_and_symlink for staging packages.
We build foo.tgz stage_as foo-${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
