  36 /* Generic helper functions for doing 64-bit SIMD arithmetic in cases
  37    where the instruction selectors cannot generate code in-line.
  38    These are purely back-end entities and cannot be seen/referenced
  39    as clean helper functions from IR.
  40
  41    These will get called from generated code and therefore should be
  42    well behaved -- no floating point or mmx insns, just straight
  43    integer code.
  44
  45    Each function implements the correspondingly-named IR primop.
