re PR tree-optimization/32243 (ICE in vectorizable_type_promotion, at tree-vect-transform.c:2890)
PR tree-optimization/32243
* tree-vect-transform.c (vectorizable_type_promotion): Move check
for ncopies after ratio check between nunits_out and nunits_in.
(vectorizable_type_demotion): Remove single-use variable "scalar_type".
testsuite/ChangeLog:
PR tree-optimization/32243
* gcc.dg/vect/vect.exp: Add support for -O3 tests. Reset default
flags for -Os tests.
* gcc.dg/vect/03-vect-pr32243.c: New test.
