-A76 Core AArch32 unpredictable behaviors
This appendix describes the cases in which the Cortex-A76 core implementation diverges from the
preferred behavior described in Armv8 AArch32 UNPREDICTABLE behaviors.
It contains the following sections:
• A.1 Use of R15 by Instruction on page Appx-A-592.
• A.2 Load/Store accesses crossing page boundaries on page Appx-A-593.
• A.3 Armv8 Debug UNPREDICTABLE behaviors on page Appx-A-594.
• A.4 Other UNPREDICTABLE behaviors on page Appx-A-597.
