Confirmed.
(insn:TI 11 21 18 2 (set (reg:V4SF 20 xmm0 [108])
(unge:V4SF (reg:V4SF 20 xmm0 [orig:106 MEM <vector(4) float> [(float
*)&x] ] [106])
(mem/c:V4SF (symbol_ref:DI ("y") [flags 0x2] <var_decl
0x7f1d203efd80 y>) [1 MEM <vector(4) float> [(float *)&y]+0 S16 A128]))) 2796
{sse_maskcmpv4sf3}
(nil))
It should have been NLT_UQ (0x15) rather than NLT_US (NLT) (0x5)
But NLT_UQ does not exist for non-VEX encoded .
