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