I have run it now on x86-64 box with today's GCC HEAD and -m32 option.
I was not using ALT_CC_UNDER_TEST, so each test was built only once, not 4
times as with ALT_CC_UNDER_TEST. The testsuite run took 12 minutes,
5 tests aborted (one is the struct { int:0; } argument passing, the other
4 might be the same bug, but I haven't analyzed, 23 tests failed to link
(at least some of them are still testsuite bugs, e.g. the generator was
putting flexible arrays even into unions where they should not appear,
I'll keep working on it) and remaining 120 tests succeeded.
With the way the generator is written, it is not hard to e.g. generate
one fourth of the current tests for everyday use by everybody (3 minutes
testsuite run ought to be already acceptable I think) and leave the
remaining tests there enabled by some env variable or some other way
to turn more tests on.
