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
