* Sync FreeBSD's bmake branch with Juniper's internal bmake branch.Marcel Moolenaar2012-08-2238-0/+1158

* Work better with how make/bmake works:Marcel Moolenaar2012-05-242-9/+9
| | | | | | | | | | | | | | | 1. Avoid a cd back into ${.CURDIR} to run mkbuiltins when we know make will first cd into ${.OBJDIR}. Keep the cwd to what make sets it to. 2. Don't tell mkbuiltins where to write to (= ${.OBJDIR}), but where to get sources from (= ${.CURDIR}). This to compensate for point 1. This fixes a problem with bmake's mk files that optimize ${.OBJDIR} to expand to "." after changing cwd, not taking into account that the target is pretty much undoing that and not getting the full path to the object tree anymore.

| | | | | | | | | | | | | | scripts the way sysctl(8) is. The -N option, like in sysctl(8), displays only the kenv names, not their values. The -v option prints an individual kenv variable name with its value as name="value". This is the inverse of sysctl(8)'s -n flag, since the default behaviour of kenv(1) is already like sysctl(8) -n.

* sh: Use vfork in a few common cases.Jilles Tjoelker2012-02-045-0/+64
| | | | | | | | | | | | | | | | | | | | This uses vfork() for simple commands and command substitutions containing a single simple command, invoking an external program under certain conditions (no redirections or variable assignments, non-interactive shell, no job control). These restrictions limit the amount of code executed in a vforked child. There is a large speedup (for example 35%) in microbenchmarks. The difference in buildkernel is smaller (for example 0.5%) but still statistically significant. See http://lists.freebsd.org/pipermail/freebsd-hackers/2012-January/037581.html for some numbers. The use of vfork() can be disabled by setting a variable named SH_DISABLE_VFORK. Notes: svn path=/head/; revision=230998

* sh: Fix some bugs with exit status from case containing ;&.Jilles Tjoelker2012-01-151-9/+24
| | | | | | | | | | | | | | | | Also, rework evalcase() to not evaluate any tree. Instead, return the NCLISTFALLTHRU node and handle it in evaltree(). Fixed bugs: * If a ;& list with non-zero exit status is followed by an empty ;; or final list, the exit status of the case command should be equal to the exit status of the ;& list, not 0. * An empty ;& case should not reset $?.
