This is on powerpc64 BE.  It works fine on LE.

This one fails too.

I just tried this and I am still seeing failures albeit only on power 7 BE.

Note that while that run was for 32 bits it fails for 64 as well.

Like PR65484 and PR87306. 
On P7, option -mno-allow-movmisalign is added during testing, which prevents
slp happen on the code.

Fixed on trunk I suppose?  If so please also sync to the 13 branch and close
this issue.
