...uilt in serial before anything else is. AFAIU DIRS is used for lib/Support an lib/TableGen because the latter depends on the first. This is not relevant on static builds (or shared builds on Linux, IIRC) so, if the `make' scripts were smart enough, that case of DIRS could become something like PARALLEL_DIRS_IF_STATIC. That would make possible to compile the source files of both libraries at the same time. BTW, the cmake build did that (don't know if keeps doing it after the switch to explicit dependencies.) But you and Dave are right wrt recursive make hiding details of the build. A non-recursive make co...
