Getting the section and address of a label in relation to it's section statically (not at runtime)

I am trying to get the address of an instruction marked by a label in ARM assembly, in relation to it's section without rewriting an assembler. For example:

.text
nop          # 0
mov r1, r2   # 4
loop:
mov r0, #170 # 8

If I want the address of loop then I get 8, because each instruction here is 4 bytes long and it begins after two instructions.

I have to clarify I'm not looking for ldr r0, =loop, I'm looking for a command like GCC which I feed a .s file to and get something like

loop=.text+0x0000ad4e
abc=.data+0x0000007a

Thanks in advance!

Use either the nm or the objdump -t command to retrieve the information you are interested in: Before relocation happens, the symbol values printed by nm are relative to the segment beginning as you wanted.

The output looks like this:

$ nm moves.o
00000000 T attack_map
00000280 T generate_moves
00000160 T gote_in_check
         U moves_for
00000320 T play_move
00000110 T sente_in_check
000001b0 T turn_board
00000000 r turn_board.turned_board

and for objdump -t:

$ objdump -t moves.o

moves.o:     file format elf32-i386-freebsd

00000000 l    df *ABS*  00000000 moves.c
00000000 l     O .rodata    0000001d turn_board.turned_board
