    * ChangeLog (2014-05-23): Fix ChangeLog entry to refer to target
      endianness instead of host endianness.
    * tree-ssa-math-opts.c (find_bswap_or_nop_1): Likewise in dumps and
      comments.

    gcc/testsuite/
    * gcc.dg/optimize-bswaphi-1.c: Adapt test to change of dump output.
      Specify -march=z900 as an additional option.
    * gcc.dg/optimize-bswapsi-1.c: Likewise for s390 options.
    * gcc.dg/optimize-bswapsi-2.c: Likewise.
    * gcc.dg/optimize-bswapdi-3.c: Likewise for adaptation to dump change.
