-; When optimising for minimum size, we don't want to expand a div to a mul
-; and a shift sequence. As a result, the urem instruction e.g. will not be
-; expanded to a sequence of umull, lsrs, muls and sub instructions, but
-; just a call to __aeabi_uidivmod.
-;
-; When the processor features hardware division, UDIV + UREM can be turned
-; into UDIV + MLS. This prevents the library function __aeabi_uidivmod to be
-; pulled into the binary. The test uses ARMv7-M.
