<h2 class="chapter">15 Analysis and Representation of Loops</h2>
|
|
|
|
<p>GCC provides extensive infrastructure for work with natural loops, i.e.,
|
|
strongly connected components of CFG with only one entry block. This
|
|
chapter describes representation of loops in GCC, both on GIMPLE and in
|
|
RTL, as well as the interfaces to loop-related analyses (induction
|
|
variable analysis and number of iterations analysis).
