           Summary: Store of 3 constant bytes should be combined into one
                    i24 store (regression)
           Product: new-bugs

            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

The element_copy.adb test from FrontendAda started failing some time ago.  The
numbers 2, 72 and 105 are stored into three consecutive bytes.  Previously this
was turned into one i24 store of 6899714, but no longer: running "opt
-std-compile-opts" on the attached testcase no longer performs this
optimization.
