tree-optimization/110460 - fend off vector types from vectorizer
Checks
Commit Message
The following makes fending off existing vector types from vectorization
also apply to word_mode vector types. I've chosen to add a positive
list of allowed scalar types here for clarity.
Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.
PR tree-optimization/110460
* tree-vect-stmts.cc (get_related_vectype_for_scalar_type):
Only allow integral, pointer and scalar float type scalar_type.
