Well, isModSupported() will happily generate such instructions:
case OP_ADD:
if (mod.abs())
return false;
if (insn->src(s ? 0 : 1).mod.neg())
return false;
break;
and insnCanLoad:
case TYPE_S32:
case TYPE_U32:
// with u32, 0xfffff counts as 0xffffffff as well
if (reg.data.s32 > 0x7ffff || reg.data.s32 < -0x80000)
return false;
break;
