Ben, we briefly chatted about this earlier. Here's more details.
I'm trying to distribute GCC testing across nodes in a cluster that do
not share a common file system. The strategy is (roughly) to avoid
using the build tree and distribute:
1- The installed tree out of 'make install'.
2- All the files in <src>/testsuite/lib/
3- All the files in <src>/testsuite/config/
4- A complete testsuite directory (say gcc/testsuite/g++.dg/tree-ssa)
together with its closest .exp driver file (in this case ../dg.exp).
5- On the machine receiving that directory, create a site.exp defining
things like srcdir, tmpdir, G*_UNDER_TEST and execute 'runtest'.
This is working pretty well for everything outside of libstdc++. I can
reduce testing from about an hour to a few minutes (we test -m32 and -m64).
libstdc++ seems to be doing a few other manipulations of site.exp and
additional setup that's defeating my scripts. Any pointers to where I
should be looking?
If I can get this to work, it would be entirely possible to set it up on
the FSF farm (provided the distribution overhead is tolerable).
Thanks. Diego.
