Nice, thanks for testing it.

Indeed.

Ah good point. I've pushed the attached patch now. This adjusts the
values.cc files for some other distributions, and does so using
dg-additional-options not dg-options. Feel free to change existing
(mis)uses of dg-options to be dg-additional-options.
I've tested it on x86_64-linux, normally and also with
-DSIMULATOR_TEST in the test flags, just to ensure I didn't introduce
a silly syntax error for that case. I haven't tested it on a real sim
though.

commit e3b8b4f7814c54543d9b7ea3ee8cf2cb9cff351d
Author: Jonathan Wakely <jwakely@redhat.com>

libstdc++: Reduce <random> test iterations for simulators
Some of these tests take several minutes on a simulator like cris-elf,
so we can conditionally run fewer iterations. The testDiscreteDist
helper already supports custom sizes so we just need to make use of that
when { target simulator } matches.
The relevant code is sufficiently tested on other targets, so we're not
losing anything by only running a small number of iterators for sims.
libstdc++-v3/ChangeLog:
* testsuite/26_numerics/random/bernoulli_distribution/operators/values.cc:
Run fewer iterations for simulator targets.
* testsuite/26_numerics/random/binomial_distribution/operators/values.cc:
Likewise.
* testsuite/26_numerics/random/discrete_distribution/operators/values.cc:
Likewise.
* testsuite/26_numerics/random/geometric_distribution/operators/values.cc:
Likewise.
* testsuite/26_numerics/random/negative_binomial_distribution/operators/values.cc:
Likewise.
* testsuite/26_numerics/random/poisson_distribution/operators/values.cc:
Likewise.
* testsuite/26_numerics/random/uniform_int_distribution/operators/values.cc:
Likewise.
