   1/ A forward branch is executed.
   2/ The branch is predicted as not taken.
   3/ The branch is taken.

      (The EOP limit is 5 by default but may be specified as any value

   Our software solution is to detect these problematic branches in a
   linker pass and modify them as follows:
   1/ Unconditional branches - Since these are always predicted taken,
      there is no problem and no action is required.
   2/ Conditional backward branches - No problem, no action required.
   3/ Conditional forward branches - Ensure that the "inverse prediction
      bit" is set (ensure it is predicted taken).
   4/ Conditional register branches - Ensure that the "y bit" is set
      (ensure it is predicted taken).  */
