arm-cs-trace-disasm just print offset for library dso now:
0000000000002200 <memcpy>: 2200: d503201f nop 2204: 8b020024 add x4, x1, x2 2208: 8b020005 add x5, x0, x2
Add a option `-a` to print virtual offset other than offset:
# perf script -s scripts/python/arm-cs-trace-disasm.py -- -d llvm-objdump -a ... ffffb4c23200 <memcpy>: ffffb4c23200: d503201f nop ffffb4c23204: 8b020024 add x4, x1, x2 ffffb4c23208: 8b020005 add x5, x0, x2 ...
