--- Comment #6 from Easwaran Raman <eraman at google dot com> 2011-06-24 22:19:40 UTC --- Could you please test if r175384 fixes these failures? Otherwise please run one of the smaller tests with -fdump-rtl-dse1-all and -fdump-rtl-cse2 (the pass before DSE) and upload those dumps and I will take a look.
