599 * gcc -O0 by default uses r7 for the frame pointer, so it complains about our
600 * use of r7 below, unless -fomit-frame-pointer is passed. Unfortunately,
601 * passing that option is not easy when building with yotta.
602 *
603 * On the other hand, -fomit-frame-pointer is implied by any -Ox options with
604 * x !=0, which we can detect using __OPTIMIZE__ (which is also defined by
605 * clang and armcc5 under the same conditions).
606 *
607 * So, only use the optimized assembly below for optimized build, which avoids
608 * the build error and is pretty reasonable anyway.
