Especially on an SMP system, and/or when some tests sleep for a few (interminable :-) seconds. Of course, this might not be trivial, especially trying to keep the resulting Makefile.in portable. However, even if it means I'd need to use a special option to generate a GNU-make-only Makefile.in, I'd happily use the result for day to day work.IIRC, Akim Demaille posted a patch a while ago on an automake list for this, GNU make-specific. I don't recall how much work was left to do, but on my list it's a bit on the far end.
Yep: http://lists.gnu.org/archive/html/automake/2007-02/msg00015.htmlThe whole idea is to have one input file per test (say a .chk file) that produces a .log file. We can then benefit from the parallelism of make with implicit rules (exactly like for .c -> .o).
The file has slightly evolved since then but I can post an updated version if someone is interested.
