No, valgrind doesn't support ARMv9. It supports ARMv8.1 (and some 8.2 and 8.3)
instructions.
You should figure out what the actual instruction is that needs support:
disInstr(arm64): unhandled instruction 0xD65F0BFF
disInstr(arm64): 1101'0110 0101'1111 0000'1011 1111'1111
==1223== valgrind: Unrecognised instruction at address 0x4014be8.
==1223== at 0x4014BE8: _dl_sysdep_parse_arguments (dl-sysdep.c:97)
Probably easiest to disassemble ld.so and look what the instruction is at that
address/line.
Also please try dropping -mcpu=neoverse-n2 from your glibc/ld.so build and see
if that works.
