Line 249: ==Coding Gotchas== ===== Missing Division Functions (__aeabi_uidivmod, __aeabi_idiv) / No Division Support ===== This issue is actually complicated because different CPUs may not support hardware division, support it only through the floating point operations, in thumb mode, in native mode, or a combination. Also, in certain situations you may find it faster or more compact to use different methods because you may be interested in code size or performance.
