any chance you kept the dumps and can report which loops were not
vectorized/recognized with -ftree-loop-linear (so we could see if these
represent missed vectorization opportunities?)
I haven't, but it wouldn't be too much effort do this.
I'll try stage 1 tonight - i.e., to establish a base (with the latest
trunk check-out, not using -ftree-loop-linear), and then subsequently
using that flag.
Kind regards,
