Please examine the lists of potential matches below and select the ones you want, or go back to the previous page to revise the names you entered. CC: tamar matched: ...list of email addrs including your arm one... I'd never seen this before and just let bugzilla choose. I have no idea why that happened as it was my reply that showed the test cases now succeeding and I did not add to nor change the CC list there. It wasn't my intent to add that email address and I apologize.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88919 --- Comment #7 from Bill Schmidt --- But this test stopped failing on January 21, so maybe the patch was applied without the ChangeLog?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88919 --- Comment #5 from seurer at gcc dot gnu.org --- Note that the change was backported to gcc 8 (r268578) and the test case fails there now the same way.

Can you investigate a bit more? The key observation should be that compared to before the rev. the loop for (int i = 0; i < 512; ++i) { x[2*i] = x[2*i] << (i+1); x[2*i+1] = x[2*i+1] << (i+1); } should be vectorized using a vector << vector shift (rather than vector << scalar).
