  | commit gcc-17-2261-g649b2a6d9f9f
  | Author: Jeff Law <jeffrey.law@oss.qualcomm.com>
  | Date:   Wed Jul 8 12:30:56 2026 -0600
  | 
  |     [PR rtl-optimization/126136] Fix dest = cond ? x : -1 when STORE_FLAG_VALUE is -1
  |     
  |     So a while back I added support for selecting x/-1 into the ifcvt.cc by using
  |     scc and a couple ALU operations.  That code explicitly rejects STORE_FLAG_VALUE
  |     if it is not 1 or -1.
  | ... 20 lines of the commit log omitted.
