I am trying to generate the disassembly of dhrystone. The following commands were used:

aarch64-none-linux-gnu-gcc -O0 -mtune=cortex-a77 -mcpu=cortex-a77 --static -c -DHZ=60 -O2 -fno-inline -fno-pie dhry_1.c
aarch64-none-linux-gnu-gcc -O0 -mtune=cortex-a77 -mcpu=cortex-a77 --static -c -DHZ=60 -O2 -fno-inline -fno-pie dhry_2.c
aarch64-none-linux-gnu-gcc -O0 -mtune=cortex-a77 -mcpu=cortex-a77 --static -fno-pie -o dhrystone dhry_1.o dhry_2.o 

For generating the disassembly, the following command was used:

aarch64-none-linux-gnu-objdump -D -x -s -t dhrystone | tee cmdPrint_dhrystone.txt

This generates the following file (only small snippets shown here):

Disassembly of section .plt:

  4002dc:   d61f0220    br  x17

If we look at the first 4 lines:

  400270:   b00004d0    adrp    x16, 499000 <_GLOBAL_OFFSET_TABLE_+0xb8>
  400274:   f9400211    ldr x17, [x16]
  400278:   91000210    add x16, x16, #0x0
  40027c:   d61f0220    br  x17

we can see a branch instruction going to the address stored in x17 register, which is in GLOBAL_OFFSET_TABLE.

We can find the description of GLOBAL_OFFSET_TABLE in the same file. It provides the following:

There is no proper instructions defined. Its mostly .inst (undefined). I would like to know if there is any means to get a meaningful instruction disassembly of the got/plt so that i can sweep through them and know where to go next.

Any suggestions/details will be appreciated. If i am wrong in my understanding, please feel free to correct me. Thanks in advance.
