  11         a substring of the message, but strcmp with the whole message.  Ifdef

  18         (mark_threaded_blocks): Remove code to truncate thread paths that
  19         cross multiple loop headers.  Instead invalidate the cached loop
  20         iteration information and handle case of a thread path walking
  21         into an irreducible region.

  27         assertions.  Add support for doing the signbit if the IEEE 128-bit

  32         (signbit<mode>2_dm_<su>ext): Add combiner pattern to eliminate
  33         the sign or zero extension instruction, since the value is always
  34         0/1.

  39         extracting SImode to a GPR register so that we can generate a

  41         for the vextuwrx instruction.
