2024-09-30 Thread Richard Biener
The following adds SLP support for vectorizing single-lane inductions with variable length vectors. This is a WIP patch, local testing for SVE and riscv is fine but the CI might discover issues. PR tree-optimization/116566 * tree-vect-loop.cc (vectorizable_induction): Handle singl
