2 ; Check that the LOH analysis does not crash when the analysed chained
3 ; contains instructions that are filtered out.
5 ; Before the fix for <rdar://problem/16041712>, these cases were removed
6 ; from the main container. Now, the deterministic container does not allow
7 ; to remove arbitrary values, so we have to live with garbage values.
