            Bug ID: 46911
           Summary: Wrong alignment on conditional store
           Product: libraries
           Version: 11.0
          Hardware: Other
                OS: All
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: Common Code Generator Code
          Assignee: unassignedbugs at nondot.org
          Reporter: kparzysz at quicinc.com
                CC: llvm-bugs at lists.llvm.org
            Blocks: 46725

The original commit introducing part-word LL/SC expansion omitted alignment
update on the conditional store by accident.  This lead to incorrect code
generated for sub-32-bit atomic operations.

This mainly affects Hexagon.

This is fixed in master in 7b114446c320de542c50c4c02f566e5d18adee33.
