sbrk problem

[halvbanan]

i can't see how i can deallocate the memory that i allocated using sbrk ecall, i tried loading a negative number onto a7 and sycall it but it said negative heap amount, this is an unsafe practice because it can give others possibilities for memory leaks

It is not possible to deallocate with sbrk in RARS. There is not a good way to allocate and deallocate memory like malloc and free. It is possible to make a memory allocator in assembly that provides C like allocation on top of sbrk.
