            Bug ID: 65369
           Summary: [5 Regression] nettle test failure on
                    powerpc64le-linux-gnu when built with -O3
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: doko at gcc dot gnu.org

seen with trunk r221254, works with -O3 on the 4.9 branch, the following test
fails with -O3 on the trunk:

hash input address: 0x100253b0451
Got:

dd4111dd66913ae2 f39adfbc438214d6

Expected:

e33b4ddc9c38f219 9c3e7b164fcc0536
Aborted (core dumped)
FAIL: md4

it's enough to build the md4.c file with -O2.
