  | commit gcc-17-5220-g78f0a4e05820
  | Author: Andrew Stubbs <ams@baylibre.com>
  | Date:   Tue Mar 17 10:40:56 2026 +0000
  | 
  |     rtl: Allow "(mem:<vecmode> (reg:<vecmode>))"
  |     
  |     This patch makes the middle-end adjustments needed to allow a MEM to take a
  |     vector of addresses in order to read/write a non-contiguous vector of data.
  |     Mostly the changes don't have to do anything besides letting the vectors pass.
  | ... 59 lines of the commit log omitted.
