Which brings the inner loop to:

L2C:            mov     RBX,-8[RBP]
                mov     CL,[RBX][R8]
                cmp     CL,R9B
                setnbe  DIL
                movzx   EDI,DIL
                add     R11,RDI
                cmp     R9B,CL
                sbb     RSI,0FFFFFFFFh
                inc     R8
                cmp     R8,-010h[RBP]
                jb      L2C
