Disassembly file with functions and their instructions only.

Is there a possibility to use *fromelf* or any other tool to generate a disassembly file from elf file but with function names and their instructions only?

Something similar to the following format:

myFunction
0x060058d8:       2201 ." MOVS r2,#1
0x060058da:       2801 .( CMP r0,#1
0x060058dc:       d100 .. BNE 0x60058e0 ; myFunction + 8
0x060058de:       2202 ." MOVS r2,#2
0x060058e0:       8808 .. LDRH r0,[r1,#0]

  • How does this differ markedly from what it does now?

        .text_6
        QUADSPI_Valid_WriteBuffer
            0x200001e8:    e92d4ff8    -..O    PUSH     {r3-r11,lr}
            0x200001ec:    4682        .F      MOV      r10,r0
            0x200001ee:    4689        .F      MOV      r9,r1
            0x200001f0:    0014        ..      MOVS     r4,r2
            0x200001f2:    f05f0b00    _...    MOVS     r11,#0
            0x200001f6:    2500        .%      MOVS     r5,#0
            0x200001f8:    2600        .&      MOVS     r6,#0
            0x200001fa:    2700        .'      MOVS     r7,#0
            0x200001fc:    f05f0800    _...    MOVS     r8,#0
            0x20000200:    2000        .       MOVS     r0,#0

    Most people would probably run a script against the output to reformat, trim or crop the content, perhaps in Perl or AWK?

    Heck, if you're a C programmer, it's the sort of thing you should be able to code pretty quickly.
