When I use older version aarch64 objdump (2.24) to disassemble
aarch64 vmlinux, I get the result like below.
There is no space between sp and offset.
ffff800008010000 <dw_apb_ictl_handle_irq>:
ffff800008010000: d503233f hint #0x19
ffff800008010004: a9bc7bfd stp x29, x30, [sp,#-64]!
ffff800008010008: 90011e60 adrp x0, ffff80000a3dc000 <num_ictlrs>
ffff80000801000c: 910003fd mov x29, sp
ffff800008010010: a9025bf5 stp x21, x22, [sp,#32]
When I use newer version aarch64 objdump (2.35), I get
the result like below.
ffff800008010000 <dw_apb_ictl_handle_irq>:
ffff800008010000: d503233f paciasp

Add no space support of regular expression for old version objdump.
