  "message": "[X86] Use kmovw, not kmovq, for VK16 copies without BWI (#200337)\n\n`copyPhysReg` selected `KMOVQkk_EVEX` for a `$k -\u003e $k` VK16 copy on a\n`+egpr` (APX) subtarget even without BWI, but `KMOVQ` requires BWI. Use\n`KMOVW` instead.\n\nThis bug was found by a large run of Opus 4.7 looking for bugs in LLVM.",
