[Bug target/18911] New: mmix-knuth-mmixware testsuite failure: g++.dg/init/array16.C execution

[hp at gcc dot gnu dot org]

With LAST_UPDATED: "Thu Dec  9 10:50:49 UTC 2004" I get:
WARNING: program timed out.
FAIL: g++.dg/init/array16.C execution test

No particular hint in g++.log.
The host machine is a Celeron 2.6GHz.

This is a new test, introduced between "Thu Dec  9 03:56:14 UTC 2004"
and above.  Looking at the test, it seems it is simply a bit too long
execution-wise and at least not fit for simulator targets.
Does it really need e.g. in the order of 4e6 iterations to accomplish
its goal?  Or can that number be divided by say 10000;
 s/elt buffer[4111222]/elt buffer[411]/ ?

Hmm, the testcase was added so we could see that we could compile the program in short time.

Re: comment #1.  So, restrict the test to compile-only?

Test passed "Tue Jul 26 21:00:09 UTC 2005"
Failed again "Wed Jul 27 09:56:50 UTC 2005".
This time the host is a x86_64-unknown-linux-gnu; amd64 2GHz, PC3200 DDR.
(no use opening a separate PR; same basic problem).
Smells like a performance regression.  Or some cron jobs got in the way.
For the record, "libstdc++.sum 25_algorithms/search_n/iterator.cc" started
timing out too.
