- gcc/
- * tree-vect-slp.c (vect_slp_analyze_bb_1): Split out core part
- of vect_analyze_bb here.
- (vect_analyze_bb): Loop over vector sizes calling vect_analyze_bb_1.
-
- gcc/testsuite/
- * lib/target-supports.exp (check_effective_target_vect64): New.
- * gcc.dg/vect/bb-slp-11.c: Expect the error message twice in case
- of multiple vector sizes.
- * gcc.dg/vect/bb-slp-26.c: New.
