New Revision: 352539
URL: https://svnweb.freebsd.org/changeset/base/352539

Log:
  Pull in r371066 from upstream clang trunk (by Justin Hibbits):
  
    Add -m(no)-spe to clang
  
    Summary:
    r337347 added support for the Signal Processing Engine (SPE) to LLVM.
    This follows that up with the clang side.
  
    This adds -mspe and -mno-spe, to match GCC.
