commit r16-7036-gf7454da3346105c972c5bf598263dafe74a7f2e0 Author: Richard Biener <[email protected]> Date: Mon Jan 26 09:07:38 2026 +0100 Fixup gcc.dg/vect/costmodel/x86_64/costmodel-vect-epil-1.c This makes 512 vector size explicit to avoid FAIL with -march that selects a 256 default. * gcc.dg/vect/costmodel/x86_64/costmodel-vect-epil-1.c: Use -mprefer-vector-width=512.
