/* Loop and basic block vectorizer.
This file contains drivers for the three vectorizers:
(1) loop vectorizer (inter-iteration parallelism),
(2) loop-aware SLP (intra-iteration parallelism) (invoked by the loop
vectorizer)
(3) BB vectorizer (out-of-loops), aka SLP
The rest of the vectorizer's code is organized as follows:
- tree-vect-loop.c - loop specific parts such as reductions, etc. These are
used by drivers (1) and (2).
- tree-vect-loop-manip.c - vectorizer's loop control-flow utilities, used by
drivers (1) and (2).
- tree-vect-slp.c - BB vectorization specific analysis and transformation,
used by drivers (2) and (3).
- tree-vect-stmts.c - statements analysis and transformation (used by all).
- tree-vect-data-refs.c - vectorizer specific data-refs analysis and
manipulations (used by all).
- tree-vect-patterns.c - vectorizable code patterns detector (used by all)
Here's a poor attempt at illustrating that:
tree-vectorizer.c:
