... from 19 instructions to 9 instructions. ■ Example 5.17 Now suppose that we are using an ARM9 E processor with the ARMv5E extensions. We can rewrite qmac again so that the compiler uses the new ARMv5E ... int *. ARM architectures up to ARMv5TE do not support unaligned pointers. To detect them, run the program on an ARM with an alignment checking trap. For example, you can configure the...
