Pointers and dynamic objects are probably fine given the ability to do indirect loads, which I assume they have (Side note: I have built b-trees on FPGAs before, and these kinds of data structures are smaller than you think). It's actually pure code size that is the problem here rather than specific capabilities, as long as the hardware supports those instructions.
Instead of assembly instructions taking time in these architectures, they take space. You will have a capacity of 1000-100000 instructions (including all the branches you might take), and then the chip is full. To get past that limit, you have to store state to RAM and then reconfigure the array to continue computing.
