commit r16-4363-g08970b2cb27931cf7e28842948b8a96a777be2a3 Author: Stefan Schulze Frielinghaus <[email protected]> Date: Fri Oct 10 15:02:09 2025 +0200 testsuite: Fix vector-subscript-4.c [PR116421] Verify we don't have any vector temporaries in the IL at least until ISEL which may introduce VEC_EXTRACTs on targets which support non-constant indices (see PR116421). As a pass I chose NRV for no particular reason except that it is literally the last pass prior ISEL. At least at time of writing this. gcc/testsuite/ChangeLog: PR testsuite/116421 * c-c++-common/vector-subscript-4.c: Check for vectors prior ISEL.
