   8 Analysis and Representation of Loops
   9 ------------------------------------

  11 GCC provides extensive infrastructure for work with natural loops, i.e.,
  12 strongly connected components of CFG with only one entry block.  This
  13 chapter describes representation of loops in GCC, both on GIMPLE and in
  14 RTL, as well as the interfaces to loop-related analyses (induction
  15 variable analysis and number of iterations analysis).
