See:
http://gcc.gnu.org/ml/libstdc++/2007-09/msg00089.html
Some of the older cruft (-j1 mandated) has been removed from the libstdc++
Makefiles, but the older problem remains.
"This is because there is basically one large call to runtest, which then runs
on one processor. And I have not found any way to convince runtest to run its
test cases in parallel."
This could also be categorized as testsuite.

We can just split make check up into make check1 make check2 make check3 make check4 make check5 make check6 ... where the old "make check" is equivalent to make check[1-n] in terms of test coverage. This will allow make -j4 check to run make check1 make check2 make check3 make check4 all at the same time. This should speed things up greatly on current hardware. Seems simple enough: I feel a bit silly for not having thought of this before. This is of relatively high priority given the time requirement for libstdc++ testing. -benjamin -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33612 ^ permalink raw reply [flat|nested] 7+ messages in thread
