FEAT_MEC support was introduced in [1]. However, the dc instruction was
missing these encodings:
- DC CIPAE
- DC CIGDPAE
Furthermore, the Arm ARM states that FEAT_MEC is an optional extension,
introduced for v9.2-a.
Therefore, these sysregs:
- MECIDR_EL2
- MECID_P0_EL2
- MECID_A0_EL2
- MECID_P1_EL2
- MECID_A1_EL2
- VMECID_P_EL2
- VMECID_A_EL2
- MECID_RL_A_EL3
which were introduced in that commit now require -march=armv9.2-a at the very
least to be enabled, as well as the dc encodings.
opcodes/ChangeLog:
* aarch64-opc.c (aarch64_sys_regs_dc): Add "cipae" and "cigdpae".
* aarch64-sys-regs.def: Add V8_7A as a requirement for the above system
registers.
