tree-optimization/114249 - ICE with BB reduction vectorization
When we scrap the last def of an odd lane numbered BB reduction
we can end up recording a pattern def which will later wreck
code generation. The following puts this logic where it better
belongs, avoiding this issue.
PR tree-optimization/114249
* tree-vect-slp.cc (vect_build_slp_instance): Move making
a BB reduction lane number even ...
(vect_slp_check_for_roots): ... here to avoid leaking
pattern defs.
* gcc.dg/vect/bb-slp-pr114249.c: New testcase.
