===== Heap Pointers Needs To Be Aligned =====
I can not state at this time how many processors support unaligned memory access natively, but from what I know unaligned memory access is more expensive than aligned. And, a good many structures which have fields greater than one byte in size a lot of times are allocated on the heap. So from this you can see how big of a performance hit you could take. Not to mention the bug that would be introduced if running under a processor which does not even handle unaligned memory access gracefully, and by that I meant at the very least raising an exception of some sort so the code can crash and show the problem.
===== Missing Division Functions (__aeabi_uidivmod, __aeabi_idiv)
This is caused by using GCC and not linking with ''libgcc''. You ''NEED TO'' link with ''libgcc'' when using GCC. For information about why you should link and information about ''libgcc'', read [[Libgcc]] and [[GCC_Cross-Compiler]].
