Summary

  • Track the active SPEC CPU2006 configuration with a per-case cfg.stamp.
    This rebuilds the ELF, rootfs, and firmware when the selected CFG changes,
    including when switching back to a previously used CFG.
  • Disable GCC SLP vectorization only for 416.gamess in the GCC 15.2
    rva23u64 LMUL1/2/4/8 configuration to avoid the compiler ICE.
  • Keep LTO, regular vectorization, and LMUL m8 enabled for 416.gamess.
