            Bug ID: 65093
           Summary: [5 Regression]
                    26_numerics/random/binomial_distribution/operators/val
                    ues.cc times out
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hp at gcc dot gnu.org
              Host: x86_64-linux-gnu
            Target: cris-elf

This test used to pass.  Since a commit in the range (220738:220744]it fails
for cris-elf as follows:

Running
/tmp/hpautotest-gcc1/gcc/libstdc++-v3/testsuite/libstdc++-dg/conformance.exp
...
[...]

WARNING: program timed out.
FAIL: 26_numerics/random/binomial_distribution/operators/values.cc execution
test

(no further information in the .log file)

There were no changes to libstdc++-v3 in the revision range.  Apparently the
middle-end changed such that code quality suffered enough that the test now
times out on the machine where I run autototests.  I'm going to bisect the
middle-end changes in the revision range and inspect the code.
