This information is contained in an optional .PPC.EMB.apuinfo section in the ELF-format object file. This document provides the official mapping between Motorola Book E Implementation Standard APUs and the numeric APU IDs that are used in the APUinfo section. See “APU Information Section” in Chapter 3, “Object Files,” of the PowerPC e500 Application Binary Interface, for more details on the format and usage of this section. 1.2 Motivation Freescale Semiconductor, Inc... The APU information is intended primarily to allow link-time checks of compatibility between object files to avoid obvious errors. For example, because both AltiVec and the signal processing engine (SPE) APU use the same instruction encodings for different instructions, linking an object file that requires AltiVec instructions with an...
