[BINUTILS, AARCH64, 3/8] Add Pointer Arithmetic instructions in Memory Tagging Extension
This patch is part of the patch series to add support for ARMv8.5-A
Memory Tagging Extensions which is an optional extension to
ARMv8.5-A and is enabled using the +memtag command line option.
This patch add support to the Pointer Arithmetic instructions from
MTE. These are the following instructions added in this patch:
- SUBP <Xd>, <Xn|SP>, <Xm|SP>
- SUBPS <Xd>, <Xn|SP>, <Xm|SP>
- CMPP <Xn|SP>, <Xm|SP>
where CMPP is an alias to SUBPS XZR, <Xn|SP>, <Xm|SP>
where
<Xd> : Is the 64-bit destination GPR.
<Xn|SP> : Is the 64-bit first source GPR or Stack pointer.
<Xm|SP> : Is the 64-bit second source GPR or Stack pointer.
