- $NetBSD$ rcsids - Fixed so that .[A-Z]* targets that do not match keywords are ignored as Posix mandates - Added .PHONY target keyword 1995-06-14 19:18:37 +04:00			`# @(#)Makefile 5.2 (Berkeley) 12/28/90`

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. 2000-12-30 05:05:20 +03:00			`make.c parse.c str.c suff.c targ.c trace.c var.c util.c`

Back out the .PATH.c changes. The .depend problem (and others) will be fixed using the new .NOPATH make feature instead. 1997-05-09 01:11:01 +04:00			`.PATH: ${.CURDIR}/lst.lib`

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. 2001-10-31 06:59:42 +03:00			`main.o: ${OBJS:Nmain.o} ${MAKEFILE}`
