-/* 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:
- loop_vect() loop_aware_slp() slp_vect()
