[2/3] Vectorize inductions that are live after the loop
2016-06-03 Alan Hayward <alan.hayward@arm.com>
[2/3] Vectorize inductions that are live after the loop
gcc/
* tree-vect-loop.c (vect_analyze_loop_operations): Allow live stmts.
(vectorizable_reduction): Check for new relevant state.
(vectorizable_live_operation): vectorize live stmts using
BIT_FIELD_REF. Remove special case for gimple assigns stmts.
* tree-vect-stmts.c (is_simple_and_all_uses_invariant): New function.
(vect_stmt_relevant_p): Check for stmts which are only used live.
(process_use): Use of a stmt does not inherit it's live value.
(vect_mark_stmts_to_be_vectorized): Simplify relevance inheritance.
(vect_analyze_stmt): Check for new relevant state.
* tree-vectorizer.h (vect_relevant): New entry for a stmt which is used
outside the loop, but not inside it.
testsuite/
* gcc.dg/tree-ssa/pr64183.c: Ensure test does not vectorize.
* testsuite/gcc.dg/vect/no-scevccp-vect-iv-2.c: Remove xfail.
* gcc.dg/vect/vect-live-1.c: New test.
* gcc.dg/vect/vect-live-2.c: New test.
* gcc.dg/vect/vect-live-3.c: New test.
* gcc.dg/vect/vect-live-4.c: New test.
* gcc.dg/vect/vect-live-5.c: New test.
* gcc.dg/vect/vect-live-slp-1.c: New test.
* gcc.dg/vect/vect-live-slp-2.c: New test.
* gcc.dg/vect/vect-live-slp-3.c: New test.
