christos a73d3d97ca Provide a new .if commands(<target>) primitive that returns true if the
target has commands associated with it.

sommerfeld 3274266e5f Delete forceSerial; just use compatMake for that.
Add -N flag to *really* not execute any commands (useful when using
the -d flags to debug usr/src/Makefile)
Document -N
Update documentation of -n to mention that it still executes commands
for targets marked .MAKE so that the -N/-n distinction is clear.

sommerfeld a804073cac Add a token-passing scheme to allow a recursive make to successfully
use -j; all make's in a recursive build cooperate to limit the total
number of jobs, using a token-passing scheme.

The current token passing algorithm is similar to the one implemented
by gmake; there is a single pipe which is inherited through the entire
process hierarchy; tokens are obtained by reading a byte from the
"read end" of the pipe, and are returned by writing them to the "write
end".  This exact algorithm is likely to change in the future.

Implementation details:
 - Use the new trace facility to allow measurement of the
effectiveness of different token-passing schemes
 - Get a token in MakeStartJobs(), return it in Make_Update()
 - Eliminate Job_Full() and the jobFull global since they are
redundant with token system.
 - Add an "internal" -J option (to pass the token pipe fd's down to
submakes) and a -T option for tracing.
 - Change how compatMake is forced so that -j means something when
inherited by submakes.
 - When waiting for a token, poll the token-passing pipe as well as
the output pipes of existing jobs.

christos 73e15c3ea3 :u modifier a'la uniq(1) [from der Mouse] 2000-09-05 17:57:52 +00:00
sjg cd8908a299 Rats! ${FOO:=bar} is a common usage of the SysV = modifier.
To avoid that, we now do ::[+?!]*= but the SysV = modifier can
conflict with any new modifier.  At there are currently no Makefiles
in our tree that use ${FOO::=bar}
2000-06-01 02:29:21 +00:00
sjg 339f702f71 Implemented a set of assignment modifiers. These solve obscure
problems such as using modifiers on .for loop iterators derived from
local variables (eg .TARGET).
Unless the variable already exists in a global context, these assignments are
local to the current context (this is usually what is wanted).
2000-05-30 02:32:21 +00:00
sjg 5fe132c5cb Added the :U :D :L :P :! and :@ modifiers as used by ODE make.
These allow some very useful magic in the makefiles.
The comment in var.c describing their behaviour is mostly lifted
from ODE make, but the implementation of the modifiers themselves
is quite different (much simpler) due to divergence of our code base.

thorpej 5a0addc0ef Add a mechanism for specifying that ${.CURDIR} will be searched last
in the presence of .PATH directives by specifying:

.PATH: .DOTLAST

This will be used to fixup the build system to work with both crypto-us
and crypto-intl sub-trees.

up-to-date, even when they are not. This is to simulate our current
make install behavior with proper dependencies.

christos 8819044d2a [initial version of the substitution/regexp changes were courtesy of Der Mouse]
- fix the variable substitution code in make [PR/2748]
      1. change s/a/b/ so that it substitutes the first occurance of the
	 pattern on each word, not only the first word.
      2. add flag '1' to the variable substitution so that the substitutions
	 get performed only once.

  ***THIS IS AN INCOMPATIBLE CHANGE!***

  Unfortunately there was no way to make things consistent without
  modifying the current behavior. Fortunately none of our Makefiles
  depended on this.

	    OLD:

		VAR      = aa1 aa2 aa3 aa4

		S/a/b/   = ba1 aa2 aa3 aa4
		S/a/b/g  = bb1 bb2 bb3 bb4

	    NEW:

		VAR      = aa1 aa2 aa3 aa4

		S/a/b/   = ba1 ba2 ba3 ba4
		S/a/b/1  = ba1 aa2 aa3 aa4
		S/a/b/g  = bb1 bb2 bb3 bb4
		S/a/b/1g = bb1 aa2 aa3 aa4

- add regexp variable substitution via 'C/foo/bar/' [PR/2752]

- add variable quoting via the ${VAR:Q} modifier. This is useful when running
  recursive invocations of make(1):

	make VAR=${VAR:Q}

  will always work... (This may prove useful in the kernel builds...) [PR/2981]

christos 61067003d8 Minor:
- ${.PREFIX} should never contain a full pathname
    - Fixed gcc -Wall warnings
Major:
    - compatMake is now FALSE. This means that we are now running in
      full pmake mode:
	  * rules on dependency lines can be executed in parallel and or
	    out of sequence:

	    foo: bar baz

	    can fire the rule for baz before the rule for bar is fired.
	    To enforce bar to be fired before baz, another rule needs to be
	    added. [bar: baz]
	  * adjacent shell commands in a target are now executed by a single
	    invocation of the shell, not one invocation of the shell per line
      (compatMake can be turned off using the -B flag)
    - The -j flag now works... I.e. make -j 4 will fork up to four jobs in
      parallel when it can. The target name is printed before each burst
      of output caused by the target execution as '--- target ---', when j > 1
    - I have changed all the Makefiles so that they work with make -j N, and
      I have tested the whole netbsd by:
	  'make -j 4 cleandir; make -j 4 depend; make -j 4; make -j 4 install'
    - I have not compiled or tested this version of make with -DREMOTE.

pk f0e170dc10 Introduced ${.OBJDIR}. The variable is similar to .CURDIR but points at
the directory where make builds the targets. It can be used to clean up
those cumbersome Makefiles that have to guess at the "obj" directory.
