Thanks :)

we put all those constants into the constant pool. ARM supports position
independent code efficently, since its program counter is a regular
register as well. We can load, modify or even jump to the addresses which
are stored in the constant pool. Constant pools are dynamically put into
the jit code, except when we need tightly coupled instruction pairs. Those
must not be broken by a constant pool.
