New Revision: 324511
URL: https://svnweb.freebsd.org/changeset/base/324511

Log:
  Do exception offset computations in 64 bits, not 32.
  
  This fixes clang-built binaries on a gcc powerpc64 world.  Gets us one step
  closer to a clang-built world.  The same change was made in later upstream
  binutils.
