        lb      a1,0(a5) // load -40
        lui     a0,%hi(.LC0)
        lui     a4,%hi(c)
        addi    a5,a1,9 //a5 = -31
        slli    a5,a5,48 
        srli    a5,a5,48 // a5 = -31
        sltu    a1,a5,a1 // -31 <u -40 ? false
        neg     a1,a1 // 0
        or      a1,a1,a5 // -31
        slli    a1,a1,48
        srli    a1,a1,48

I don't see anything wrong here ... Unless I missed something (is lb a signed
load byte?)
