reinoud a233fbd53e Fix major bug in make(1) ... due to shadowing of the dotLast path used for
the .DOTLAST primitive by a boolean variable with the same name, this whole
mechanism was broken ... it doesn't save much stat calls but it was wrong.

Thanks to Jason Thorpe for the other shadow-variable fixing patches he
made.

tv 053d51348d Overhaul the initialization and handling of .OBJDIR:
* Replace chdir_verify_path() with Main_SetObjdir(), which can be called
  externally, and can take a "const char *".  (There's a lot of non-const
  "char *" passing around in var.c of what should be const strings....)

* Rewrite the initial "find my .OBJDIR" code to make use of the new
  function.  This still functions as it had in the past, but the comment
  above this block was changed to reflect reality:  if MAKEOBJDIRPREFIX
  or MAKEOBJDIR are set in the environment, then *only that value* is
  tried; make does not fall back to obj.MACHINE, obj, and /usr/obj/`pwd`
  as it would without these env vars set.

* Add a new special target, .OBJDIR:, which when parsed will cause make to
  change to a new object directory and reset .OBJDIR, and PWD in the
  environment.  This will allow some makefiles (mainly, src/tools)
  to override the default objdir semantics in order to add custom logic.

sommerfeld 8a39635d34 Back out debug cruft. 2000-12-30 02:06:42 +00:00
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 aa49881371 - Merge in FreeBSD and Lite2 changes.
- Fix bug where a non-archive target with a .a suffix would always
  be considered to be out of date, since it does not have a TOC.

christos 5c1983c016 - Move -D flags from Makefile to config.h and explain what they do. Add
-Wall -Wno-unused to CFLAGS. Add new define SYSVVARSUB to enable SysV
  style variable substitutions and enable them.
- Add SunOS style command substitutions via SUNSHCMD
- Fix core dump with '{variable = value'

christos 57cad0d107 Jonathan Stone's fixes:
main.c:	Remove double include of <sys/resource.h>; if MACHINE is defined, use
	that instead of uname.
